compositor: Implement JSON-timeline logging
Logging is activated and deactivated with the debug key binding 't'.
When activated, it creates a new log file, where it records the events.
The log file contains events and detailed object information entries in
JSON format, and is meant to be parsed in sequence from beginning to the
end.
The emitted events are mostly related to the output repaint cycle, like
when repaint begins, is submitted to GPU, and when it completes on a
vblank. This is recorded per-output. Also some per-surface events are
recorded, including when surface damage is flushed.
To reduce the log size, events refer to objects like outputs and
surfaces by id numbers. Detailed object information is emitted only as
needed: on the first object occurrence, and afterwards only if
weston_timeline_object::force_refresh asks for it.
The detailed information for surfaces includes the string returned by
weston_surface::get_label. Therefore it is important to set
weston_timeline_object::force_refresh = 1 whenever the string would
change, so that the new details get recorded.
A rudimentary parser and SVG generator can be found at:
https://github.com/ppaalanen/wesgr
The timeline logs can answer questions including:
- How does the compositor repaint cycle work timing-wise?
- When was the vblank deadline missed?
- What is the latency from surface commit to showing the new content on
screen?
- How long does it take to process the scenegraph?
v2: weston_surface::get_description renamed to get_label.
v3: reafctor a bit into fprint_quoted_string().

Split the geometry information from weston_surface out into weston_view
The weston_surface structure is split into two structures:
* The weston_surface structure storres everything required for a
client-side or server-side surface. This includes buffers; callbacks;
backend private data; input, damage, and opaque regions; and a few other
bookkeeping bits.
* The weston_view structure represents an entity in the scenegraph and
storres all of the geometry information. This includes clip region,
alpha, position, and the transformation list as well as all of the
temporary information derived from the geometry state. Because a view,
and not a surface, is a scenegraph element, the view is what is placed
in layers and planes.
There are a few things worth noting about the surface/view split:
1. This is *not* a modification to the protocol. It is, instead, a
modification to Weston's internal scenegraph to allow a single surface
to exist in multiple places at a time. Clients are completely unaware
of how many views to a particular surface exist.
2. A view is considered a direct child of a surface and is destroyed when
the surface is destroyed. Because of this, the view.surface pointer is
always valid and non-null.
3. The compositor's surface_list is replaced with a view_list. Due to
subsurfaces, building the view list is a little more complicated than
it used to be and involves building a tree of views on the fly whenever
subsurfaces are used. However, this means that backends can remain
completely subsurface-agnostic.
4. Surfaces and views both keep track of which outputs they are on.
5. The weston_surface structure now has width and height fields. These
are populated when a new buffer is attached before surface.configure
is called. This is because there are many surface-based operations
that really require the width and height and digging through the views
didn't work well.

compositor: introduce sub-surfaces
Implement the basic protocol for sub-surfaces:
- expose wl_subcompositor global interface
- error checking on protocol calls
- associate a parent wl_surface to a sub-surface
- introduce the sub-surface role, which is exclusive
- an implementation of the wl_subsurface interface
- allow nesting of sub-surfaces
- proper surface transformation inheritance from parent to sub-surfaces
- two different modes of wl_surface.commit for sub-surfaces
- hook sub-surfaces up to repaint by modifying the repaint list code
Struct weston_subsurface is dynamically allocated. For sub-surfaces, it
is completely populated.
For parent surfaces, weston_subsurface acts only as a link for stacking
order purposes. The wl_resource is unused, parent_destroy_listener is
not registered, the transform is not linked, etc.
Sub-surfaces are not added directly into layers for display or input.
Instead, they are hooked up via the sub-surface list present in parent
weston_surface. This way sub-surfaces are inherently linked to the
parent surface, and cannot be displayed unless the parent is mapped,
too. This also eases restacking, as only the parent will be in a layer
list. Also, only the main surface should be subject to shell actions.
The surface list rebuilding in weston_output_repaint() is modified to
process sub-surface lists, if they are non-empty. The sub-surface list
always contains the parent, too, unless empty. The collection of
frame_callback_list is moved to a later loop, to streamline the surface
list rebuild functions.
Features still lacking are:
- full-surface alpha support for compound windows
Changes in v2:
- fix a bug in surface mapping: commit a sub-surface would cause the
main surface to never be mapped.
- remove debug printfs
- detect attempt of making a surface its own parent
- always zero-alloc weston_subsurface
- apply wl_subsurface.set_position in commit, not immediately
- add weston_surface_to_subsurface()
- implement sub-surface commit modes parent-cached and independent
- implement wl_subcompositor.destroy and wl_subsurface.destroy
Changes in v3:
- rebased, and use the new transform inheritance code
- squashed the commit "add sub-surfaces to repaint list"
- fixed a buffer reference leak in commit_from_cache()
- Rewrite the sub-surface destructor code, and make it leave the
wl_subsurface protocol object inert, if one destroys the corresponding
wl_surface.
- replaced set_commit_mode with set_sync and set_desync
- allowed sub-surface nesting, and fixed repaint accordingly
- implemented nested sub-surface commit modes
- Made the sub-surface order changes from wl_subsurface.place_above and
.place_below to be applied when the parent surface state is applied,
instead of immediately. This conforms with the protocol specification
now.

backend private data; input, damage, and opaque regions; and a few other
bookkeeping bits.
* The weston_view structure represents an entity in the scenegraph and
storres all of the geometry information. This includes clip region,
alpha, position, and the transformation list as well as all of the
temporary information derived from the geometry state. Because a view,
and not a surface, is a scenegraph element, the view is what is placed
in layers and planes.
There are a few things worth noting about the surface/view split:
1. This is *not* a modification to the protocol. It is, instead, a
modification to Weston's internal scenegraph to allow a single surface
to exist in multiple places at a time. Clients are completely unaware
of how many views to a particular surface exist.
2. A view is considered a direct child of a surface and is destroyed when
the surface is destroyed. Because of this, the view.surface pointer is
always valid and non-null.
3. The compositor's surface_list is replaced with a view_list. Due to
subsurfaces, building the view list is a little more complicated than
it used to be and involves building a tree of views on the fly whenever
subsurfaces are used. However, this means that backends can remain
completely subsurface-agnostic.
4. Surfaces and views both keep track of which outputs they are on.
5. The weston_surface structure now has width and height fields. These
are populated when a new buffer is attached before surface.configure
is called. This is because there are many surface-based operations
that really require the width and height and digging through the views
didn't work well.

compositor: Assign new views to the primary plane
When we create a new view, assign it to the primary plane from the
beginning.
Currently, every view across the compositor will be assigned to a plane
during every repaint cycle of every output: the DRM renderer's
assign_planes hook will either move a view to a drm_plane, or to the
primary plane if a suitable drm_plane could not be found for the output
it is on. There are no other assign_planes implementation, and the
fallback when none is provided, is to assign every view to the primary
plane.
DRM's behaviour is undesirable in multi-output situations, since it
means that views which were on a plane on one output will be demoted to
the primary plane; doing this causes damage, which will cause a spurious
repaint for the output. This spurious repaint will have no effect on the
other output, but it will do the same demotion of views to the primary
plane, which will again provoke a repaint on the other output.
With a simple fix for this behaviour (i.e. not moving views which are
only visible on other outputs), the following behaviour is observed:
- outputs A and B are present
- views A and B are created for those outputs respectively, with SHM
buffers attached; view->plane == NULL for both
- current buffer content for views A and B are uploaded to the
renderer
- output A runs its repaint cycle, and sets keep_buffer to false on
surface B's output, as it can never be promoted to a plane; it does
not move view B to another plane
- output B runs its repaint cycle, and moves view B to the primary
plane
- weston_view_assign_to_plane has work to do (as the plane is changing
from NULL to the primary plane), calls weston_surface_damage and
calls weston_surface_damage
- weston_surface_damage re-uploads buffer content, possibly from
nowhere at all; e508ce6a notes that this behaviour is broken
Assigning views to the primary plane when created makes it possible to
fix the DRM assign_planes implementation: assign_planes will always set
keep_buffer to true if there is any chance the buffer can ever be
promoted to a plane, regardless of view configruation. If the buffer
cannot be promoted to a plane, it must by definition never migrate from
the primary plane. This means that there is no opportunity to hit the
same issue, where the buffer content has already been discarded, but
weston_view_assign_to_plane is not a no-op.

compositor: set presentation.presented flags
Change weston_output_finish_frame() signature so that backends are
required to set the flags, that will be reported on the Presentation
'presented' event. This is meant for output-wide feedback flags. Flags
that vary per wl_surface are subject for the following patch.
All start_repaint_loop functions use the special private flag
PRESENTATION_FEEDBACK_INVALID to mark, that this call of
weston_output_finish_frame() cannot trigger the 'presented' event. If it
does, we now hit an assert, and should then investigate why a fake update
triggered Presentation feedback.
DRM:
Page flip is always vsync'd, and always gets the completion timestamp
from the kernel which should correspond well to hardware. Completion is
triggered by the kernel/hardware.
Vblank handler is only used with the broken planes path, therefore do
not report VSYNC, because we cannot guarantee all the planes updated at
the same time. We cannot set the INVALID, because it would abort the
compositor if the broken planes path was ever used. This is a hack that
will get fixed with nuclear pageflip support in the future.
fbdev:
No vsync, update done by copy, no completion event from hardware, and
completion time is totally fake.
headless:
No real output to update.
RDP:
Guessing that maybe no vsync, fake time, and copy make sense (pixels
sent over network). Also no event that the pixels have been shown?
RPI:
Presumably Dispmanx updates are vsync'd. We get a completion event from
the driver, but need to read the clock ourselves, so the completion time
is somewhat unreliable. Zero-copy flag not implemented though it would
be theoretically possible with EGL clients (zero-copy is a per-surface
flag anyway, so in this patch).
Wayland:
No information how the host compositor is doing updates, so make a safe
guess without assuming vsync or hardware completion event. While we do
get some timestamp from the host compositor, it is not the completion
time. Would need to hook to the Presentation extension of the host
compositor to get more accurate flags.
X11:
No idea about vsync, completion event, or copying. Also the timestamp is

Rename wayland-compositor to weston
This rename addresses a few problems around the split between core
Wayland and the wayland-demos repository.
1) Initially, we had one big repository with protocol code, sample
compositor and sample clients. We split that repository to make it
possible to implement the protocol without pulling in the sample/demo
code. At this point, the compositor is more than just a "demo" and
wayland-demos doesn't send the right message. The sample compositor
is a useful, self-contained project in it's own right, and we want to
move away from the "demos" label.
2) Another problem is that the wayland-demos compositor is often
called "the wayland compsitor", but it's really just one possible
compositor. Existing X11 compositors are expected to add Wayland
support and then gradually phase out/modularize the X11 support, for
example. Conversely, it's hard to talk about the wayland-demos
compositor specifically as opposed to, eg, the wayland protocol or a
wayland compositor in general.
We are also renaming the repo to weston, and the compositor
subdirectory to src/, to emphasize that the main "output" is the
compositor.

Split the geometry information from weston_surface out into weston_view
The weston_surface structure is split into two structures:
* The weston_surface structure storres everything required for a
client-side or server-side surface. This includes buffers; callbacks;
backend private data; input, damage, and opaque regions; and a few other
bookkeeping bits.
* The weston_view structure represents an entity in the scenegraph and
storres all of the geometry information. This includes clip region,
alpha, position, and the transformation list as well as all of the
temporary information derived from the geometry state. Because a view,
and not a surface, is a scenegraph element, the view is what is placed
in layers and planes.
There are a few things worth noting about the surface/view split:
1. This is *not* a modification to the protocol. It is, instead, a
modification to Weston's internal scenegraph to allow a single surface
to exist in multiple places at a time. Clients are completely unaware
of how many views to a particular surface exist.
2. A view is considered a direct child of a surface and is destroyed when
the surface is destroyed. Because of this, the view.surface pointer is
always valid and non-null.
3. The compositor's surface_list is replaced with a view_list. Due to
subsurfaces, building the view list is a little more complicated than
it used to be and involves building a tree of views on the fly whenever
subsurfaces are used. However, this means that backends can remain
completely subsurface-agnostic.
4. Surfaces and views both keep track of which outputs they are on.
5. The weston_surface structure now has width and height fields. These
are populated when a new buffer is attached before surface.configure
is called. This is because there are many surface-based operations
that really require the width and height and digging through the views
didn't work well.

compositor: introduce sub-surfaces
Implement the basic protocol for sub-surfaces:
- expose wl_subcompositor global interface
- error checking on protocol calls
- associate a parent wl_surface to a sub-surface
- introduce the sub-surface role, which is exclusive
- an implementation of the wl_subsurface interface
- allow nesting of sub-surfaces
- proper surface transformation inheritance from parent to sub-surfaces
- two different modes of wl_surface.commit for sub-surfaces
- hook sub-surfaces up to repaint by modifying the repaint list code
Struct weston_subsurface is dynamically allocated. For sub-surfaces, it
is completely populated.
For parent surfaces, weston_subsurface acts only as a link for stacking
order purposes. The wl_resource is unused, parent_destroy_listener is
not registered, the transform is not linked, etc.
Sub-surfaces are not added directly into layers for display or input.
Instead, they are hooked up via the sub-surface list present in parent
weston_surface. This way sub-surfaces are inherently linked to the
parent surface, and cannot be displayed unless the parent is mapped,
too. This also eases restacking, as only the parent will be in a layer
list. Also, only the main surface should be subject to shell actions.
The surface list rebuilding in weston_output_repaint() is modified to
process sub-surface lists, if they are non-empty. The sub-surface list
always contains the parent, too, unless empty. The collection of
frame_callback_list is moved to a later loop, to streamline the surface
list rebuild functions.
Features still lacking are:
- full-surface alpha support for compound windows
Changes in v2:
- fix a bug in surface mapping: commit a sub-surface would cause the
main surface to never be mapped.
- remove debug printfs
- detect attempt of making a surface its own parent
- always zero-alloc weston_subsurface
- apply wl_subsurface.set_position in commit, not immediately
- add weston_surface_to_subsurface()
- implement sub-surface commit modes parent-cached and independent
- implement wl_subcompositor.destroy and wl_subsurface.destroy
Changes in v3:
- rebased, and use the new transform inheritance code
- squashed the commit "add sub-surfaces to repaint list"
- fixed a buffer reference leak in commit_from_cache()
- Rewrite the sub-surface destructor code, and make it leave the
wl_subsurface protocol object inert, if one destroys the corresponding
wl_surface.
- replaced set_commit_mode with set_sync and set_desync
- allowed sub-surface nesting, and fixed repaint accordingly
- implemented nested sub-surface commit modes
- Made the sub-surface order changes from wl_subsurface.place_above and
.place_below to be applied when the parent surface state is applied,
instead of immediately. This conforms with the protocol specification
now.

Split the geometry information from weston_surface out into weston_view
The weston_surface structure is split into two structures:
* The weston_surface structure storres everything required for a
client-side or server-side surface. This includes buffers; callbacks;
backend private data; input, damage, and opaque regions; and a few other
bookkeeping bits.
* The weston_view structure represents an entity in the scenegraph and
storres all of the geometry information. This includes clip region,
alpha, position, and the transformation list as well as all of the
temporary information derived from the geometry state. Because a view,
and not a surface, is a scenegraph element, the view is what is placed
in layers and planes.
There are a few things worth noting about the surface/view split:
1. This is *not* a modification to the protocol. It is, instead, a
modification to Weston's internal scenegraph to allow a single surface
to exist in multiple places at a time. Clients are completely unaware
of how many views to a particular surface exist.
2. A view is considered a direct child of a surface and is destroyed when
the surface is destroyed. Because of this, the view.surface pointer is
always valid and non-null.
3. The compositor's surface_list is replaced with a view_list. Due to
subsurfaces, building the view list is a little more complicated than
it used to be and involves building a tree of views on the fly whenever
subsurfaces are used. However, this means that backends can remain
completely subsurface-agnostic.
4. Surfaces and views both keep track of which outputs they are on.
5. The weston_surface structure now has width and height fields. These
are populated when a new buffer is attached before surface.configure
is called. This is because there are many surface-based operations
that really require the width and height and digging through the views
didn't work well.

The weston_surface structure is split into two structures:
* The weston_surface structure storres everything required for a
client-side or server-side surface. This includes buffers; callbacks;
backend private data; input, damage, and opaque regions; and a few other
bookkeeping bits.
* The weston_view structure represents an entity in the scenegraph and
storres all of the geometry information. This includes clip region,
alpha, position, and the transformation list as well as all of the
temporary information derived from the geometry state. Because a view,
and not a surface, is a scenegraph element, the view is what is placed
in layers and planes.
There are a few things worth noting about the surface/view split:
1. This is *not* a modification to the protocol. It is, instead, a
modification to Weston's internal scenegraph to allow a single surface
to exist in multiple places at a time. Clients are completely unaware
of how many views to a particular surface exist.
2. A view is considered a direct child of a surface and is destroyed when
the surface is destroyed. Because of this, the view.surface pointer is
always valid and non-null.
3. The compositor's surface_list is replaced with a view_list. Due to
subsurfaces, building the view list is a little more complicated than
it used to be and involves building a tree of views on the fly whenever
subsurfaces are used. However, this means that backends can remain
completely subsurface-agnostic.
4. Surfaces and views both keep track of which outputs they are on.
5. The weston_surface structure now has width and height fields. These
are populated when a new buffer is attached before surface.configure
is called. This is because there are many surface-based operations
that really require the width and height and digging through the views
didn't work well.

Split the geometry information from weston_surface out into weston_view
The weston_surface structure is split into two structures:
* The weston_surface structure storres everything required for a
client-side or server-side surface. This includes buffers; callbacks;
backend private data; input, damage, and opaque regions; and a few other
bookkeeping bits.
* The weston_view structure represents an entity in the scenegraph and
storres all of the geometry information. This includes clip region,
alpha, position, and the transformation list as well as all of the
temporary information derived from the geometry state. Because a view,
and not a surface, is a scenegraph element, the view is what is placed
in layers and planes.
There are a few things worth noting about the surface/view split:
1. This is *not* a modification to the protocol. It is, instead, a
modification to Weston's internal scenegraph to allow a single surface
to exist in multiple places at a time. Clients are completely unaware
of how many views to a particular surface exist.
2. A view is considered a direct child of a surface and is destroyed when
the surface is destroyed. Because of this, the view.surface pointer is
always valid and non-null.
3. The compositor's surface_list is replaced with a view_list. Due to
subsurfaces, building the view list is a little more complicated than
it used to be and involves building a tree of views on the fly whenever
subsurfaces are used. However, this means that backends can remain
completely subsurface-agnostic.
4. Surfaces and views both keep track of which outputs they are on.
5. The weston_surface structure now has width and height fields. These
are populated when a new buffer is attached before surface.configure
is called. This is because there are many surface-based operations
that really require the width and height and digging through the views
didn't work well.

Split the geometry information from weston_surface out into weston_view
The weston_surface structure is split into two structures:
* The weston_surface structure storres everything required for a
client-side or server-side surface. This includes buffers; callbacks;
backend private data; input, damage, and opaque regions; and a few other
bookkeeping bits.
* The weston_view structure represents an entity in the scenegraph and
storres all of the geometry information. This includes clip region,
alpha, position, and the transformation list as well as all of the
temporary information derived from the geometry state. Because a view,
and not a surface, is a scenegraph element, the view is what is placed
in layers and planes.
There are a few things worth noting about the surface/view split:
1. This is *not* a modification to the protocol. It is, instead, a
modification to Weston's internal scenegraph to allow a single surface
to exist in multiple places at a time. Clients are completely unaware
of how many views to a particular surface exist.
2. A view is considered a direct child of a surface and is destroyed when
the surface is destroyed. Because of this, the view.surface pointer is
always valid and non-null.
3. The compositor's surface_list is replaced with a view_list. Due to
subsurfaces, building the view list is a little more complicated than

Split the geometry information from weston_surface out into weston_view
The weston_surface structure is split into two structures:
* The weston_surface structure storres everything required for a
client-side or server-side surface. This includes buffers; callbacks;
backend private data; input, damage, and opaque regions; and a few other
bookkeeping bits.
* The weston_view structure represents an entity in the scenegraph and
storres all of the geometry information. This includes clip region,
alpha, position, and the transformation list as well as all of the
temporary information derived from the geometry state. Because a view,
and not a surface, is a scenegraph element, the view is what is placed
in layers and planes.
There are a few things worth noting about the surface/view split:
1. This is *not* a modification to the protocol. It is, instead, a
modification to Weston's internal scenegraph to allow a single surface
to exist in multiple places at a time. Clients are completely unaware
of how many views to a particular surface exist.
2. A view is considered a direct child of a surface and is destroyed when
the surface is destroyed. Because of this, the view.surface pointer is
always valid and non-null.
3. The compositor's surface_list is replaced with a view_list. Due to
subsurfaces, building the view list is a little more complicated than
it used to be and involves building a tree of views on the fly whenever
subsurfaces are used. However, this means that backends can remain
completely subsurface-agnostic.
4. Surfaces and views both keep track of which outputs they are on.
5. The weston_surface structure now has width and height fields. These
are populated when a new buffer is attached before surface.configure
is called. This is because there are many surface-based operations
that really require the width and height and digging through the views
didn't work well.

client-side or server-side surface. This includes buffers; callbacks;
backend private data; input, damage, and opaque regions; and a few other
bookkeeping bits.
* The weston_view structure represents an entity in the scenegraph and
storres all of the geometry information. This includes clip region,
alpha, position, and the transformation list as well as all of the
temporary information derived from the geometry state. Because a view,
and not a surface, is a scenegraph element, the view is what is placed
in layers and planes.
There are a few things worth noting about the surface/view split:
1. This is *not* a modification to the protocol. It is, instead, a
modification to Weston's internal scenegraph to allow a single surface
to exist in multiple places at a time. Clients are completely unaware
of how many views to a particular surface exist.
2. A view is considered a direct child of a surface and is destroyed when
the surface is destroyed. Because of this, the view.surface pointer is
always valid and non-null.
3. The compositor's surface_list is replaced with a view_list. Due to
subsurfaces, building the view list is a little more complicated than
it used to be and involves building a tree of views on the fly whenever
subsurfaces are used. However, this means that backends can remain
completely subsurface-agnostic.
4. Surfaces and views both keep track of which outputs they are on.
5. The weston_surface structure now has width and height fields. These
are populated when a new buffer is attached before surface.configure
is called. This is because there are many surface-based operations
that really require the width and height and digging through the views
didn't work well.

Rename wayland-compositor to weston
This rename addresses a few problems around the split between core
Wayland and the wayland-demos repository.
1) Initially, we had one big repository with protocol code, sample
compositor and sample clients. We split that repository to make it
possible to implement the protocol without pulling in the sample/demo
code. At this point, the compositor is more than just a "demo" and
wayland-demos doesn't send the right message. The sample compositor
is a useful, self-contained project in it's own right, and we want to
move away from the "demos" label.
2) Another problem is that the wayland-demos compositor is often
called "the wayland compsitor", but it's really just one possible
compositor. Existing X11 compositors are expected to add Wayland
support and then gradually phase out/modularize the X11 support, for
example. Conversely, it's hard to talk about the wayland-demos
compositor specifically as opposed to, eg, the wayland protocol or a
wayland compositor in general.
We are also renaming the repo to weston, and the compositor
subdirectory to src/, to emphasize that the main "output" is the
compositor.

Split the geometry information from weston_surface out into weston_view
The weston_surface structure is split into two structures:
* The weston_surface structure storres everything required for a
client-side or server-side surface. This includes buffers; callbacks;
backend private data; input, damage, and opaque regions; and a few other
bookkeeping bits.
* The weston_view structure represents an entity in the scenegraph and
storres all of the geometry information. This includes clip region,
alpha, position, and the transformation list as well as all of the
temporary information derived from the geometry state. Because a view,
and not a surface, is a scenegraph element, the view is what is placed
in layers and planes.
There are a few things worth noting about the surface/view split:
1. This is *not* a modification to the protocol. It is, instead, a
modification to Weston's internal scenegraph to allow a single surface
to exist in multiple places at a time. Clients are completely unaware
of how many views to a particular surface exist.
2. A view is considered a direct child of a surface and is destroyed when
the surface is destroyed. Because of this, the view.surface pointer is
always valid and non-null.
3. The compositor's surface_list is replaced with a view_list. Due to
subsurfaces, building the view list is a little more complicated than
it used to be and involves building a tree of views on the fly whenever
subsurfaces are used. However, this means that backends can remain
completely subsurface-agnostic.
4. Surfaces and views both keep track of which outputs they are on.
5. The weston_surface structure now has width and height fields. These
are populated when a new buffer is attached before surface.configure
is called. This is because there are many surface-based operations
that really require the width and height and digging through the views
didn't work well.

Split the geometry information from weston_surface out into weston_view
The weston_surface structure is split into two structures:
* The weston_surface structure storres everything required for a
client-side or server-side surface. This includes buffers; callbacks;
backend private data; input, damage, and opaque regions; and a few other
bookkeeping bits.
* The weston_view structure represents an entity in the scenegraph and
storres all of the geometry information. This includes clip region,
alpha, position, and the transformation list as well as all of the
temporary information derived from the geometry state. Because a view,
and not a surface, is a scenegraph element, the view is what is placed
in layers and planes.
There are a few things worth noting about the surface/view split:
1. This is *not* a modification to the protocol. It is, instead, a
modification to Weston's internal scenegraph to allow a single surface
to exist in multiple places at a time. Clients are completely unaware
of how many views to a particular surface exist.
2. A view is considered a direct child of a surface and is destroyed when
the surface is destroyed. Because of this, the view.surface pointer is
always valid and non-null.
3. The compositor's surface_list is replaced with a view_list. Due to
subsurfaces, building the view list is a little more complicated than
it used to be and involves building a tree of views on the fly whenever
subsurfaces are used. However, this means that backends can remain
completely subsurface-agnostic.
4. Surfaces and views both keep track of which outputs they are on.
5. The weston_surface structure now has width and height fields. These
are populated when a new buffer is attached before surface.configure
is called. This is because there are many surface-based operations
that really require the width and height and digging through the views
didn't work well.

Rename wayland-compositor to weston
This rename addresses a few problems around the split between core
Wayland and the wayland-demos repository.
1) Initially, we had one big repository with protocol code, sample
compositor and sample clients. We split that repository to make it
possible to implement the protocol without pulling in the sample/demo
code. At this point, the compositor is more than just a "demo" and
wayland-demos doesn't send the right message. The sample compositor
is a useful, self-contained project in it's own right, and we want to
move away from the "demos" label.
2) Another problem is that the wayland-demos compositor is often
called "the wayland compsitor", but it's really just one possible
compositor. Existing X11 compositors are expected to add Wayland
support and then gradually phase out/modularize the X11 support, for
example. Conversely, it's hard to talk about the wayland-demos
compositor specifically as opposed to, eg, the wayland protocol or a
wayland compositor in general.
We are also renaming the repo to weston, and the compositor
subdirectory to src/, to emphasize that the main "output" is the
compositor.

Split the geometry information from weston_surface out into weston_view
The weston_surface structure is split into two structures:
* The weston_surface structure storres everything required for a
client-side or server-side surface. This includes buffers; callbacks;
backend private data; input, damage, and opaque regions; and a few other
bookkeeping bits.
* The weston_view structure represents an entity in the scenegraph and
storres all of the geometry information. This includes clip region,
alpha, position, and the transformation list as well as all of the
temporary information derived from the geometry state. Because a view,
and not a surface, is a scenegraph element, the view is what is placed
in layers and planes.
There are a few things worth noting about the surface/view split:
1. This is *not* a modification to the protocol. It is, instead, a
modification to Weston's internal scenegraph to allow a single surface
to exist in multiple places at a time. Clients are completely unaware
of how many views to a particular surface exist.
2. A view is considered a direct child of a surface and is destroyed when
the surface is destroyed. Because of this, the view.surface pointer is
always valid and non-null.
3. The compositor's surface_list is replaced with a view_list. Due to
subsurfaces, building the view list is a little more complicated than
it used to be and involves building a tree of views on the fly whenever
subsurfaces are used. However, this means that backends can remain
completely subsurface-agnostic.
4. Surfaces and views both keep track of which outputs they are on.
5. The weston_surface structure now has width and height fields. These
are populated when a new buffer is attached before surface.configure
is called. This is because there are many surface-based operations
that really require the width and height and digging through the views
didn't work well.

compositor: introduce sub-surfaces
Implement the basic protocol for sub-surfaces:
- expose wl_subcompositor global interface
- error checking on protocol calls
- associate a parent wl_surface to a sub-surface
- introduce the sub-surface role, which is exclusive
- an implementation of the wl_subsurface interface
- allow nesting of sub-surfaces
- proper surface transformation inheritance from parent to sub-surfaces
- two different modes of wl_surface.commit for sub-surfaces
- hook sub-surfaces up to repaint by modifying the repaint list code
Struct weston_subsurface is dynamically allocated. For sub-surfaces, it
is completely populated.
For parent surfaces, weston_subsurface acts only as a link for stacking
order purposes. The wl_resource is unused, parent_destroy_listener is
not registered, the transform is not linked, etc.
Sub-surfaces are not added directly into layers for display or input.
Instead, they are hooked up via the sub-surface list present in parent
weston_surface. This way sub-surfaces are inherently linked to the
parent surface, and cannot be displayed unless the parent is mapped,
too. This also eases restacking, as only the parent will be in a layer
list. Also, only the main surface should be subject to shell actions.
The surface list rebuilding in weston_output_repaint() is modified to
process sub-surface lists, if they are non-empty. The sub-surface list
always contains the parent, too, unless empty. The collection of
frame_callback_list is moved to a later loop, to streamline the surface
list rebuild functions.
Features still lacking are:
- full-surface alpha support for compound windows
Changes in v2:
- fix a bug in surface mapping: commit a sub-surface would cause the
main surface to never be mapped.
- remove debug printfs
- detect attempt of making a surface its own parent
- always zero-alloc weston_subsurface
- apply wl_subsurface.set_position in commit, not immediately
- add weston_surface_to_subsurface()
- implement sub-surface commit modes parent-cached and independent
- implement wl_subcompositor.destroy and wl_subsurface.destroy
Changes in v3:
- rebased, and use the new transform inheritance code
- squashed the commit "add sub-surfaces to repaint list"
- fixed a buffer reference leak in commit_from_cache()
- Rewrite the sub-surface destructor code, and make it leave the
wl_subsurface protocol object inert, if one destroys the corresponding
wl_surface.
- replaced set_commit_mode with set_sync and set_desync
- allowed sub-surface nesting, and fixed repaint accordingly
- implemented nested sub-surface commit modes
- Made the sub-surface order changes from wl_subsurface.place_above and
.place_below to be applied when the parent surface state is applied,
instead of immediately. This conforms with the protocol specification
now.

Split the geometry information from weston_surface out into weston_view
The weston_surface structure is split into two structures:
* The weston_surface structure storres everything required for a
client-side or server-side surface. This includes buffers; callbacks;
backend private data; input, damage, and opaque regions; and a few other
bookkeeping bits.
* The weston_view structure represents an entity in the scenegraph and
storres all of the geometry information. This includes clip region,
alpha, position, and the transformation list as well as all of the
temporary information derived from the geometry state. Because a view,
and not a surface, is a scenegraph element, the view is what is placed
in layers and planes.
There are a few things worth noting about the surface/view split:
1. This is *not* a modification to the protocol. It is, instead, a
modification to Weston's internal scenegraph to allow a single surface
to exist in multiple places at a time. Clients are completely unaware
of how many views to a particular surface exist.
2. A view is considered a direct child of a surface and is destroyed when
the surface is destroyed. Because of this, the view.surface pointer is
always valid and non-null.
3. The compositor's surface_list is replaced with a view_list. Due to
subsurfaces, building the view list is a little more complicated than
it used to be and involves building a tree of views on the fly whenever
subsurfaces are used. However, this means that backends can remain
completely subsurface-agnostic.
4. Surfaces and views both keep track of which outputs they are on.
5. The weston_surface structure now has width and height fields. These
are populated when a new buffer is attached before surface.configure
is called. This is because there are many surface-based operations
that really require the width and height and digging through the views
didn't work well.

compositor: introduce weston_buffer_reference
The wl_buffer reference counting API has been inconsistent. You would
manually increment the refcount and register a destroy listener, as
opposed to calling weston_buffer_post_release(), which internally
decremented the refcount, and then removing a list item.
Replace both cases with a single function:
weston_buffer_reference(weston_buffer_reference *ref, wl_buffer *buffer)
Buffer is assigned to ref->buffer, while taking care of all the refcounting
and release posting. You take a reference by passing a non-NULL buffer, and
release a reference by passing NULL as buffer. The function uses an
internal wl_buffer destroy listener, so the pointer gets reset on
destruction automatically.
This is inspired by the pipe_resource_reference() of Mesa, and modified
by krh's suggestion to add struct weston_buffer_reference.
Additionally, when a surface gets destroyed, the associated wl_buffer
will send a release event. Often the buffer is already destroyed on
client side, so the event will be discarded by libwayland-client.

Rename wayland-compositor to weston
This rename addresses a few problems around the split between core
Wayland and the wayland-demos repository.
1) Initially, we had one big repository with protocol code, sample
compositor and sample clients. We split that repository to make it
possible to implement the protocol without pulling in the sample/demo
code. At this point, the compositor is more than just a "demo" and
wayland-demos doesn't send the right message. The sample compositor
is a useful, self-contained project in it's own right, and we want to
move away from the "demos" label.
2) Another problem is that the wayland-demos compositor is often
called "the wayland compsitor", but it's really just one possible
compositor. Existing X11 compositors are expected to add Wayland
support and then gradually phase out/modularize the X11 support, for
example. Conversely, it's hard to talk about the wayland-demos
compositor specifically as opposed to, eg, the wayland protocol or a
wayland compositor in general.
We are also renaming the repo to weston, and the compositor
subdirectory to src/, to emphasize that the main "output" is the
compositor.

in layers and planes.
There are a few things worth noting about the surface/view split:
1. This is *not* a modification to the protocol. It is, instead, a
modification to Weston's internal scenegraph to allow a single surface
to exist in multiple places at a time. Clients are completely unaware
of how many views to a particular surface exist.
2. A view is considered a direct child of a surface and is destroyed when
the surface is destroyed. Because of this, the view.surface pointer is
always valid and non-null.
3. The compositor's surface_list is replaced with a view_list. Due to
subsurfaces, building the view list is a little more complicated than
it used to be and involves building a tree of views on the fly whenever
subsurfaces are used. However, this means that backends can remain
completely subsurface-agnostic.
4. Surfaces and views both keep track of which outputs they are on.
5. The weston_surface structure now has width and height fields. These
are populated when a new buffer is attached before surface.configure
is called. This is because there are many surface-based operations
that really require the width and height and digging through the views
didn't work well.

compositor: introduce weston_buffer_reference
The wl_buffer reference counting API has been inconsistent. You would
manually increment the refcount and register a destroy listener, as
opposed to calling weston_buffer_post_release(), which internally
decremented the refcount, and then removing a list item.
Replace both cases with a single function:
weston_buffer_reference(weston_buffer_reference *ref, wl_buffer *buffer)
Buffer is assigned to ref->buffer, while taking care of all the refcounting
and release posting. You take a reference by passing a non-NULL buffer, and
release a reference by passing NULL as buffer. The function uses an
internal wl_buffer destroy listener, so the pointer gets reset on
destruction automatically.
This is inspired by the pipe_resource_reference() of Mesa, and modified
by krh's suggestion to add struct weston_buffer_reference.
Additionally, when a surface gets destroyed, the associated wl_buffer
will send a release event. Often the buffer is already destroyed on
client side, so the event will be discarded by libwayland-client.
Compositor-drm.c is converted to use weston_buffer_reference.

compositor: Implement JSON-timeline logging
Logging is activated and deactivated with the debug key binding 't'.
When activated, it creates a new log file, where it records the events.
The log file contains events and detailed object information entries in
JSON format, and is meant to be parsed in sequence from beginning to the
end.
The emitted events are mostly related to the output repaint cycle, like
when repaint begins, is submitted to GPU, and when it completes on a
vblank. This is recorded per-output. Also some per-surface events are
recorded, including when surface damage is flushed.
To reduce the log size, events refer to objects like outputs and
surfaces by id numbers. Detailed object information is emitted only as
needed: on the first object occurrence, and afterwards only if
weston_timeline_object::force_refresh asks for it.
The detailed information for surfaces includes the string returned by
weston_surface::get_label. Therefore it is important to set
weston_timeline_object::force_refresh = 1 whenever the string would
change, so that the new details get recorded.
A rudimentary parser and SVG generator can be found at:
https://github.com/ppaalanen/wesgr
The timeline logs can answer questions including:
- How does the compositor repaint cycle work timing-wise?
- When was the vblank deadline missed?
- What is the latency from surface commit to showing the new content on
screen?
- How long does it take to process the scenegraph?
v2: weston_surface::get_description renamed to get_label.
v3: reafctor a bit into fprint_quoted_string().

Split the geometry information from weston_surface out into weston_view

* The weston_view structure represents an entity in the scenegraph and

1. This is *not* a modification to the protocol. It is, instead, a
modification to Weston's internal scenegraph to allow a single surface
to exist in multiple places at a time. Clients are completely unaware
of how many views to a particular surface exist.
2. A view is considered a direct child of a surface and is destroyed when
the surface is destroyed. Because of this, the view.surface pointer is
always valid and non-null.
3. The compositor's surface_list is replaced with a view_list. Due to
subsurfaces, building the view list is a little more complicated than
it used to be and involves building a tree of views on the fly whenever
subsurfaces are used. However, this means that backends can remain
completely subsurface-agnostic.
4. Surfaces and views both keep track of which outputs they are on.
5. The weston_surface structure now has width and height fields. These
are populated when a new buffer is attached before surface.configure
is called. This is because there are many surface-based operations
that really require the width and height and digging through the views
didn't work well.

compositor: introduce sub-surfaces
Implement the basic protocol for sub-surfaces:
- expose wl_subcompositor global interface
- error checking on protocol calls
- associate a parent wl_surface to a sub-surface
- introduce the sub-surface role, which is exclusive
- an implementation of the wl_subsurface interface
- allow nesting of sub-surfaces
- proper surface transformation inheritance from parent to sub-surfaces
- two different modes of wl_surface.commit for sub-surfaces
- hook sub-surfaces up to repaint by modifying the repaint list code
Struct weston_subsurface is dynamically allocated. For sub-surfaces, it
is completely populated.
For parent surfaces, weston_subsurface acts only as a link for stacking
order purposes. The wl_resource is unused, parent_destroy_listener is
not registered, the transform is not linked, etc.
Sub-surfaces are not added directly into layers for display or input.
Instead, they are hooked up via the sub-surface list present in parent
weston_surface. This way sub-surfaces are inherently linked to the
parent surface, and cannot be displayed unless the parent is mapped,
too. This also eases restacking, as only the parent will be in a layer
list. Also, only the main surface should be subject to shell actions.
The surface list rebuilding in weston_output_repaint() is modified to
process sub-surface lists, if they are non-empty. The sub-surface list
always contains the parent, too, unless empty. The collection of
frame_callback_list is moved to a later loop, to streamline the surface
list rebuild functions.
Features still lacking are:
- full-surface alpha support for compound windows
Changes in v2:
- fix a bug in surface mapping: commit a sub-surface would cause the
main surface to never be mapped.
- remove debug printfs
- detect attempt of making a surface its own parent
- always zero-alloc weston_subsurface
- apply wl_subsurface.set_position in commit, not immediately
- add weston_surface_to_subsurface()
- implement sub-surface commit modes parent-cached and independent
- implement wl_subcompositor.destroy and wl_subsurface.destroy
Changes in v3:
- rebased, and use the new transform inheritance code
- squashed the commit "add sub-surfaces to repaint list"
- fixed a buffer reference leak in commit_from_cache()
- Rewrite the sub-surface destructor code, and make it leave the
wl_subsurface protocol object inert, if one destroys the corresponding
wl_surface.
- replaced set_commit_mode with set_sync and set_desync
- allowed sub-surface nesting, and fixed repaint accordingly
- implemented nested sub-surface commit modes
- Made the sub-surface order changes from wl_subsurface.place_above and
.place_below to be applied when the parent surface state is applied,
instead of immediately. This conforms with the protocol specification
now.

Split the geometry information from weston_surface out into weston_view
The weston_surface structure is split into two structures:
* The weston_surface structure storres everything required for a
client-side or server-side surface. This includes buffers; callbacks;
backend private data; input, damage, and opaque regions; and a few other
bookkeeping bits.
* The weston_view structure represents an entity in the scenegraph and
storres all of the geometry information. This includes clip region,
alpha, position, and the transformation list as well as all of the
temporary information derived from the geometry state. Because a view,
and not a surface, is a scenegraph element, the view is what is placed
in layers and planes.

compositor: ignore unmapped sub-surfaces for view_list
It looks like that in the great conversion introducing weston_view, one
conditional was forgotten from the code that builds the global flat list
of views. Sub-surfaces are added to the view list specially, as they are
not governed by their presence in a layer's view list, and therefore
need an explicit check for mappedness.
The bug, missing the explicit check, caused sub-surfaces to enter the
global view_list regardless of their state. This lead to the pointer
focus picking code processing them, and as the input region defaults to
infinite, picking these unmapped surfaces. Clients then get confused
about the wl_pointer.enter events with unexpected wl_surface.
To trigger this issue, it is enough to just create one additional
wl_surface and make it a sub-surface of a main surface that is or gets
mapped. Literally, just a wl_subsomcpositor_get_subsurface() call is
enough. At some point later, the unmapped sub-surface will get pointer
focus, depending on view stacking order.
Fix the issue by adding a is_mapped check when building the view_list.
Note, that 95ec0f95aa2df74c2da19e7dda24528fa8f765cc accidentally also
prevents this bug from happening, because it adds a test against the
transform.masked_boundingbox in weston_compositor_pick_view().

Split the geometry information from weston_surface out into weston_view
The weston_surface structure is split into two structures:
* The weston_surface structure storres everything required for a
client-side or server-side surface. This includes buffers; callbacks;
backend private data; input, damage, and opaque regions; and a few other
bookkeeping bits.
* The weston_view structure represents an entity in the scenegraph and
storres all of the geometry information. This includes clip region,
alpha, position, and the transformation list as well as all of the
temporary information derived from the geometry state. Because a view,
and not a surface, is a scenegraph element, the view is what is placed
in layers and planes.
There are a few things worth noting about the surface/view split:
1. This is *not* a modification to the protocol. It is, instead, a
modification to Weston's internal scenegraph to allow a single surface
to exist in multiple places at a time. Clients are completely unaware
of how many views to a particular surface exist.
2. A view is considered a direct child of a surface and is destroyed when
the surface is destroyed. Because of this, the view.surface pointer is
always valid and non-null.
3. The compositor's surface_list is replaced with a view_list. Due to
subsurfaces, building the view list is a little more complicated than
it used to be and involves building a tree of views on the fly whenever
subsurfaces are used. However, this means that backends can remain
completely subsurface-agnostic.
4. Surfaces and views both keep track of which outputs they are on.
5. The weston_surface structure now has width and height fields. These
are populated when a new buffer is attached before surface.configure
is called. This is because there are many surface-based operations
that really require the width and height and digging through the views
didn't work well.

compositor: introduce sub-surfaces
Implement the basic protocol for sub-surfaces:
- expose wl_subcompositor global interface
- error checking on protocol calls
- associate a parent wl_surface to a sub-surface
- introduce the sub-surface role, which is exclusive
- an implementation of the wl_subsurface interface
- allow nesting of sub-surfaces
- proper surface transformation inheritance from parent to sub-surfaces
- two different modes of wl_surface.commit for sub-surfaces
- hook sub-surfaces up to repaint by modifying the repaint list code
Struct weston_subsurface is dynamically allocated. For sub-surfaces, it
is completely populated.
For parent surfaces, weston_subsurface acts only as a link for stacking
order purposes. The wl_resource is unused, parent_destroy_listener is
not registered, the transform is not linked, etc.
Sub-surfaces are not added directly into layers for display or input.
Instead, they are hooked up via the sub-surface list present in parent
weston_surface. This way sub-surfaces are inherently linked to the
parent surface, and cannot be displayed unless the parent is mapped,
too. This also eases restacking, as only the parent will be in a layer
list. Also, only the main surface should be subject to shell actions.
The surface list rebuilding in weston_output_repaint() is modified to
process sub-surface lists, if they are non-empty. The sub-surface list
always contains the parent, too, unless empty. The collection of
frame_callback_list is moved to a later loop, to streamline the surface
list rebuild functions.
Features still lacking are:
- full-surface alpha support for compound windows
Changes in v2:
- fix a bug in surface mapping: commit a sub-surface would cause the
main surface to never be mapped.
- remove debug printfs
- detect attempt of making a surface its own parent
- always zero-alloc weston_subsurface
- apply wl_subsurface.set_position in commit, not immediately
- add weston_surface_to_subsurface()
- implement sub-surface commit modes parent-cached and independent
- implement wl_subcompositor.destroy and wl_subsurface.destroy
Changes in v3:
- rebased, and use the new transform inheritance code
- squashed the commit "add sub-surfaces to repaint list"
- fixed a buffer reference leak in commit_from_cache()
- Rewrite the sub-surface destructor code, and make it leave the
wl_subsurface protocol object inert, if one destroys the corresponding
wl_surface.
- replaced set_commit_mode with set_sync and set_desync
- allowed sub-surface nesting, and fixed repaint accordingly
- implemented nested sub-surface commit modes
- Made the sub-surface order changes from wl_subsurface.place_above and
.place_below to be applied when the parent surface state is applied,
instead of immediately. This conforms with the protocol specification
now.

compositor: fix sub-surface view stacking order
If you opened a window with sub-surfaces, and then raised another window
on top of that, the underlaying window's main surface was stacked
properly, but the sub-surfaces remained on top of the raised window.
IOW, the raised window was in between the other window and its
sub-surfaces.
This got broken in a7af70436b7dccfacd736626d6719b3e751fd985, "Split the
geometry information from weston_surface out into weston_view".
Fix the issues:
In view_list_add_subsurface_view(), the views need to be added to the
end of the list, not to the head. This alone fixes the above problem,
but causes the sub-surface views to be stacked irrespective of their
surface stacking order. The stacking order in this test case is fixed by
the changes to view_list_add(), but for sub-sub-surfaces a similar
change is needed in view_list_add_subsurface_view() too.
In view_list_add(), build the view list in the sub-surface stacking
order, instead of pulling the parent surface always on top. Also handle
the case, when the subsurface_list is completely empty: the parent
surface's view must still be added.

- full-surface alpha support for compound windows
Changes in v2:
- fix a bug in surface mapping: commit a sub-surface would cause the
main surface to never be mapped.
- remove debug printfs
- detect attempt of making a surface its own parent
- always zero-alloc weston_subsurface
- apply wl_subsurface.set_position in commit, not immediately
- add weston_surface_to_subsurface()
- implement sub-surface commit modes parent-cached and independent
- implement wl_subcompositor.destroy and wl_subsurface.destroy
Changes in v3:
- rebased, and use the new transform inheritance code
- squashed the commit "add sub-surfaces to repaint list"
- fixed a buffer reference leak in commit_from_cache()
- Rewrite the sub-surface destructor code, and make it leave the
wl_subsurface protocol object inert, if one destroys the corresponding
wl_surface.
- replaced set_commit_mode with set_sync and set_desync
- allowed sub-surface nesting, and fixed repaint accordingly
- implemented nested sub-surface commit modes
- Made the sub-surface order changes from wl_subsurface.place_above and
.place_below to be applied when the parent surface state is applied,
instead of immediately. This conforms with the protocol specification
now.

Split the geometry information from weston_surface out into weston_view
The weston_surface structure is split into two structures:
* The weston_surface structure storres everything required for a
client-side or server-side surface. This includes buffers; callbacks;
backend private data; input, damage, and opaque regions; and a few other
bookkeeping bits.
* The weston_view structure represents an entity in the scenegraph and
storres all of the geometry information. This includes clip region,
alpha, position, and the transformation list as well as all of the
temporary information derived from the geometry state. Because a view,
and not a surface, is a scenegraph element, the view is what is placed
in layers and planes.
There are a few things worth noting about the surface/view split:
1. This is *not* a modification to the protocol. It is, instead, a
modification to Weston's internal scenegraph to allow a single surface
to exist in multiple places at a time. Clients are completely unaware
of how many views to a particular surface exist.
2. A view is considered a direct child of a surface and is destroyed when
the surface is destroyed. Because of this, the view.surface pointer is
always valid and non-null.
3. The compositor's surface_list is replaced with a view_list. Due to
subsurfaces, building the view list is a little more complicated than
it used to be and involves building a tree of views on the fly whenever
subsurfaces are used. However, this means that backends can remain
completely subsurface-agnostic.
4. Surfaces and views both keep track of which outputs they are on.
5. The weston_surface structure now has width and height fields. These
are populated when a new buffer is attached before surface.configure
is called. This is because there are many surface-based operations
that really require the width and height and digging through the views
didn't work well.

compositor: fix sub-surface view stacking order
If you opened a window with sub-surfaces, and then raised another window
on top of that, the underlaying window's main surface was stacked
properly, but the sub-surfaces remained on top of the raised window.
IOW, the raised window was in between the other window and its
sub-surfaces.
This got broken in a7af70436b7dccfacd736626d6719b3e751fd985, "Split the
geometry information from weston_surface out into weston_view".
Fix the issues:
In view_list_add_subsurface_view(), the views need to be added to the
end of the list, not to the head. This alone fixes the above problem,
but causes the sub-surface views to be stacked irrespective of their
surface stacking order. The stacking order in this test case is fixed by
the changes to view_list_add(), but for sub-sub-surfaces a similar
change is needed in view_list_add_subsurface_view() too.
In view_list_add(), build the view list in the sub-surface stacking
order, instead of pulling the parent surface always on top. Also handle
the case, when the subsurface_list is completely empty: the parent
surface's view must still be added.

compositor: introduce sub-surfaces
Implement the basic protocol for sub-surfaces:
- expose wl_subcompositor global interface
- error checking on protocol calls
- associate a parent wl_surface to a sub-surface
- introduce the sub-surface role, which is exclusive
- an implementation of the wl_subsurface interface
- allow nesting of sub-surfaces
- proper surface transformation inheritance from parent to sub-surfaces
- two different modes of wl_surface.commit for sub-surfaces
- hook sub-surfaces up to repaint by modifying the repaint list code
Struct weston_subsurface is dynamically allocated. For sub-surfaces, it
is completely populated.
For parent surfaces, weston_subsurface acts only as a link for stacking
order purposes. The wl_resource is unused, parent_destroy_listener is
not registered, the transform is not linked, etc.
Sub-surfaces are not added directly into layers for display or input.
Instead, they are hooked up via the sub-surface list present in parent
weston_surface. This way sub-surfaces are inherently linked to the
parent surface, and cannot be displayed unless the parent is mapped,
too. This also eases restacking, as only the parent will be in a layer
list. Also, only the main surface should be subject to shell actions.
The surface list rebuilding in weston_output_repaint() is modified to
process sub-surface lists, if they are non-empty. The sub-surface list
always contains the parent, too, unless empty. The collection of
frame_callback_list is moved to a later loop, to streamline the surface
list rebuild functions.
Features still lacking are:
- full-surface alpha support for compound windows
Changes in v2:
- fix a bug in surface mapping: commit a sub-surface would cause the
main surface to never be mapped.
- remove debug printfs
- detect attempt of making a surface its own parent
- always zero-alloc weston_subsurface
- apply wl_subsurface.set_position in commit, not immediately
- add weston_surface_to_subsurface()
- implement sub-surface commit modes parent-cached and independent
- implement wl_subcompositor.destroy and wl_subsurface.destroy

- rebased, and use the new transform inheritance code

compositor: introduce sub-surfaces
Implement the basic protocol for sub-surfaces:
- expose wl_subcompositor global interface
- error checking on protocol calls
- associate a parent wl_surface to a sub-surface
- introduce the sub-surface role, which is exclusive
- an implementation of the wl_subsurface interface
- allow nesting of sub-surfaces
- proper surface transformation inheritance from parent to sub-surfaces
- two different modes of wl_surface.commit for sub-surfaces
- hook sub-surfaces up to repaint by modifying the repaint list code
Struct weston_subsurface is dynamically allocated. For sub-surfaces, it
is completely populated.
For parent surfaces, weston_subsurface acts only as a link for stacking
order purposes. The wl_resource is unused, parent_destroy_listener is
not registered, the transform is not linked, etc.
Sub-surfaces are not added directly into layers for display or input.
Instead, they are hooked up via the sub-surface list present in parent
weston_surface. This way sub-surfaces are inherently linked to the
parent surface, and cannot be displayed unless the parent is mapped,
too. This also eases restacking, as only the parent will be in a layer
list. Also, only the main surface should be subject to shell actions.
The surface list rebuilding in weston_output_repaint() is modified to
process sub-surface lists, if they are non-empty. The sub-surface list
always contains the parent, too, unless empty. The collection of
frame_callback_list is moved to a later loop, to streamline the surface
list rebuild functions.
Features still lacking are:
- full-surface alpha support for compound windows
Changes in v2:
- fix a bug in surface mapping: commit a sub-surface would cause the
main surface to never be mapped.
- remove debug printfs
- detect attempt of making a surface its own parent
- always zero-alloc weston_subsurface
- apply wl_subsurface.set_position in commit, not immediately
- add weston_surface_to_subsurface()
- implement sub-surface commit modes parent-cached and independent
- implement wl_subcompositor.destroy and wl_subsurface.destroy
Changes in v3:
- rebased, and use the new transform inheritance code
- squashed the commit "add sub-surfaces to repaint list"
- fixed a buffer reference leak in commit_from_cache()
- Rewrite the sub-surface destructor code, and make it leave the
wl_subsurface protocol object inert, if one destroys the corresponding
wl_surface.
- replaced set_commit_mode with set_sync and set_desync
- allowed sub-surface nesting, and fixed repaint accordingly
- implemented nested sub-surface commit modes
- Made the sub-surface order changes from wl_subsurface.place_above and
.place_below to be applied when the parent surface state is applied,
instead of immediately. This conforms with the protocol specification
now.

Rename wayland-compositor to weston
This rename addresses a few problems around the split between core
Wayland and the wayland-demos repository.
1) Initially, we had one big repository with protocol code, sample
compositor and sample clients. We split that repository to make it
possible to implement the protocol without pulling in the sample/demo
code. At this point, the compositor is more than just a "demo" and
wayland-demos doesn't send the right message. The sample compositor
is a useful, self-contained project in it's own right, and we want to
move away from the "demos" label.
2) Another problem is that the wayland-demos compositor is often
called "the wayland compsitor", but it's really just one possible
compositor. Existing X11 compositors are expected to add Wayland
support and then gradually phase out/modularize the X11 support, for
example. Conversely, it's hard to talk about the wayland-demos
compositor specifically as opposed to, eg, the wayland protocol or a
wayland compositor in general.
We are also renaming the repo to weston, and the compositor
subdirectory to src/, to emphasize that the main "output" is the
compositor.

Split the geometry information from weston_surface out into weston_view
The weston_surface structure is split into two structures:
* The weston_surface structure storres everything required for a
client-side or server-side surface. This includes buffers; callbacks;
backend private data; input, damage, and opaque regions; and a few other
bookkeeping bits.
* The weston_view structure represents an entity in the scenegraph and
storres all of the geometry information. This includes clip region,
alpha, position, and the transformation list as well as all of the
temporary information derived from the geometry state. Because a view,
and not a surface, is a scenegraph element, the view is what is placed
in layers and planes.
There are a few things worth noting about the surface/view split:
1. This is *not* a modification to the protocol. It is, instead, a
modification to Weston's internal scenegraph to allow a single surface
to exist in multiple places at a time. Clients are completely unaware
of how many views to a particular surface exist.
2. A view is considered a direct child of a surface and is destroyed when
the surface is destroyed. Because of this, the view.surface pointer is
always valid and non-null.
3. The compositor's surface_list is replaced with a view_list. Due to
subsurfaces, building the view list is a little more complicated than
it used to be and involves building a tree of views on the fly whenever
subsurfaces are used. However, this means that backends can remain
completely subsurface-agnostic.
4. Surfaces and views both keep track of which outputs they are on.
5. The weston_surface structure now has width and height fields. These
are populated when a new buffer is attached before surface.configure
is called. This is because there are many surface-based operations
that really require the width and height and digging through the views
didn't work well.

compositor: Implement JSON-timeline logging
Logging is activated and deactivated with the debug key binding 't'.
When activated, it creates a new log file, where it records the events.
The log file contains events and detailed object information entries in
JSON format, and is meant to be parsed in sequence from beginning to the
end.
The emitted events are mostly related to the output repaint cycle, like
when repaint begins, is submitted to GPU, and when it completes on a
vblank. This is recorded per-output. Also some per-surface events are
recorded, including when surface damage is flushed.
To reduce the log size, events refer to objects like outputs and
surfaces by id numbers. Detailed object information is emitted only as
needed: on the first object occurrence, and afterwards only if
weston_timeline_object::force_refresh asks for it.
The detailed information for surfaces includes the string returned by
weston_surface::get_label. Therefore it is important to set
weston_timeline_object::force_refresh = 1 whenever the string would
change, so that the new details get recorded.
A rudimentary parser and SVG generator can be found at:
https://github.com/ppaalanen/wesgr
The timeline logs can answer questions including:
- How does the compositor repaint cycle work timing-wise?
- When was the vblank deadline missed?
- What is the latency from surface commit to showing the new content on
screen?
- How long does it take to process the scenegraph?
v2: weston_surface::get_description renamed to get_label.
v3: reafctor a bit into fprint_quoted_string().

compositor: Clear only the the damage that was actually repainted
Instead of clearing the whole output region after a repaint, clear
only the regions that were actually painted. This way, the damage
added when a surface moves from the primary plane to another one is
kept while this region is obscured by the opaque region. This allows
the contents below an overlaid surface to be culled, but to make this
work properly, it is also necessary to change the way previous damage
is drawn.
Consider the following scenario: a surface is moved to an overlay plane
leaving some damage in the primary plane. On the following frame, the
surface on the overlay moves, revealing part of the damaged region on
the primary plane. On the frame after that, the overlaid surface moves
back to its previous position obscuring the region of the primary plane
repainted before. At this point, the repainted region was added to the
output's previous damage so that it is draw to both buffers. But since
this region is now obscured, the redrawing is skipped. If the overlaid
surface moves again revealing this region, one of the buffers actually
contains the wrong content.
To fix this problem, this patch ensures that any previous damage that
would be lost is actually preserved by folding it back into the
primary plane damage just before repainting.

the contents below an overlaid surface to be culled, but to make this
work properly, it is also necessary to change the way previous damage
is drawn.
Consider the following scenario: a surface is moved to an overlay plane
leaving some damage in the primary plane. On the following frame, the
surface on the overlay moves, revealing part of the damaged region on
the primary plane. On the frame after that, the overlaid surface moves
back to its previous position obscuring the region of the primary plane
repainted before. At this point, the repainted region was added to the
output's previous damage so that it is draw to both buffers. But since
this region is now obscured, the redrawing is skipped. If the overlaid
surface moves again revealing this region, one of the buffers actually
contains the wrong content.
To fix this problem, this patch ensures that any previous damage that
would be lost is actually preserved by folding it back into the
primary plane damage just before repainting.

compositor: Implement JSON-timeline logging
Logging is activated and deactivated with the debug key binding 't'.
When activated, it creates a new log file, where it records the events.
The log file contains events and detailed object information entries in
JSON format, and is meant to be parsed in sequence from beginning to the
end.
The emitted events are mostly related to the output repaint cycle, like
when repaint begins, is submitted to GPU, and when it completes on a
vblank. This is recorded per-output. Also some per-surface events are
recorded, including when surface damage is flushed.
To reduce the log size, events refer to objects like outputs and
surfaces by id numbers. Detailed object information is emitted only as
needed: on the first object occurrence, and afterwards only if
weston_timeline_object::force_refresh asks for it.
The detailed information for surfaces includes the string returned by
weston_surface::get_label. Therefore it is important to set
weston_timeline_object::force_refresh = 1 whenever the string would
change, so that the new details get recorded.
A rudimentary parser and SVG generator can be found at:
https://github.com/ppaalanen/wesgr
The timeline logs can answer questions including:
- How does the compositor repaint cycle work timing-wise?
- When was the vblank deadline missed?
- What is the latency from surface commit to showing the new content on
screen?
- How long does it take to process the scenegraph?
v2: weston_surface::get_description renamed to get_label.
v3: reafctor a bit into fprint_quoted_string().

compositor: set presentation.presented flags
Change weston_output_finish_frame() signature so that backends are
required to set the flags, that will be reported on the Presentation
'presented' event. This is meant for output-wide feedback flags. Flags
that vary per wl_surface are subject for the following patch.
All start_repaint_loop functions use the special private flag
PRESENTATION_FEEDBACK_INVALID to mark, that this call of
weston_output_finish_frame() cannot trigger the 'presented' event. If it
does, we now hit an assert, and should then investigate why a fake update
triggered Presentation feedback.
DRM:
Page flip is always vsync'd, and always gets the completion timestamp
from the kernel which should correspond well to hardware. Completion is
triggered by the kernel/hardware.
Vblank handler is only used with the broken planes path, therefore do
not report VSYNC, because we cannot guarantee all the planes updated at
the same time. We cannot set the INVALID, because it would abort the
compositor if the broken planes path was ever used. This is a hack that
will get fixed with nuclear pageflip support in the future.
fbdev:
No vsync, update done by copy, no completion event from hardware, and
completion time is totally fake.
headless:
No real output to update.
RDP:
Guessing that maybe no vsync, fake time, and copy make sense (pixels
sent over network). Also no event that the pixels have been shown?
RPI:
Presumably Dispmanx updates are vsync'd. We get a completion event from
the driver, but need to read the clock ourselves, so the completion time
is somewhat unreliable. Zero-copy flag not implemented though it would
be theoretically possible with EGL clients (zero-copy is a per-surface
flag anyway, so in this patch).
Wayland:
No information how the host compositor is doing updates, so make a safe
guess without assuming vsync or hardware completion event. While we do
get some timestamp from the host compositor, it is not the completion
time. Would need to hook to the Presentation extension of the host
compositor to get more accurate flags.
X11:
No idea about vsync, completion event, or copying. Also the timestamp is
a fake.

compositor: Implement JSON-timeline logging
Logging is activated and deactivated with the debug key binding 't'.
When activated, it creates a new log file, where it records the events.
The log file contains events and detailed object information entries in
JSON format, and is meant to be parsed in sequence from beginning to the
end.
The emitted events are mostly related to the output repaint cycle, like
when repaint begins, is submitted to GPU, and when it completes on a
vblank. This is recorded per-output. Also some per-surface events are
recorded, including when surface damage is flushed.
To reduce the log size, events refer to objects like outputs and
surfaces by id numbers. Detailed object information is emitted only as
needed: on the first object occurrence, and afterwards only if
weston_timeline_object::force_refresh asks for it.
The detailed information for surfaces includes the string returned by
weston_surface::get_label. Therefore it is important to set
weston_timeline_object::force_refresh = 1 whenever the string would
change, so that the new details get recorded.
A rudimentary parser and SVG generator can be found at:
https://github.com/ppaalanen/wesgr
The timeline logs can answer questions including:
- How does the compositor repaint cycle work timing-wise?
- When was the vblank deadline missed?
- What is the latency from surface commit to showing the new content on
screen?
- How long does it take to process the scenegraph?
v2: weston_surface::get_description renamed to get_label.
v3: reafctor a bit into fprint_quoted_string().

compositor: introduce weston_buffer_reference
The wl_buffer reference counting API has been inconsistent. You would
manually increment the refcount and register a destroy listener, as
opposed to calling weston_buffer_post_release(), which internally
decremented the refcount, and then removing a list item.
Replace both cases with a single function:
weston_buffer_reference(weston_buffer_reference *ref, wl_buffer *buffer)
Buffer is assigned to ref->buffer, while taking care of all the refcounting
and release posting. You take a reference by passing a non-NULL buffer, and
release a reference by passing NULL as buffer. The function uses an
internal wl_buffer destroy listener, so the pointer gets reset on
destruction automatically.
This is inspired by the pipe_resource_reference() of Mesa, and modified
by krh's suggestion to add struct weston_buffer_reference.
Additionally, when a surface gets destroyed, the associated wl_buffer
will send a release event. Often the buffer is already destroyed on
client side, so the event will be discarded by libwayland-client.
Compositor-drm.c is converted to use weston_buffer_reference.

Rename wayland-compositor to weston
This rename addresses a few problems around the split between core
Wayland and the wayland-demos repository.
1) Initially, we had one big repository with protocol code, sample
compositor and sample clients. We split that repository to make it
possible to implement the protocol without pulling in the sample/demo
code. At this point, the compositor is more than just a "demo" and
wayland-demos doesn't send the right message. The sample compositor
is a useful, self-contained project in it's own right, and we want to
move away from the "demos" label.
2) Another problem is that the wayland-demos compositor is often
called "the wayland compsitor", but it's really just one possible
compositor. Existing X11 compositors are expected to add Wayland
support and then gradually phase out/modularize the X11 support, for
example. Conversely, it's hard to talk about the wayland-demos
compositor specifically as opposed to, eg, the wayland protocol or a
wayland compositor in general.
We are also renaming the repo to weston, and the compositor
subdirectory to src/, to emphasize that the main "output" is the
compositor.

compositor: introduce sub-surfaces
Implement the basic protocol for sub-surfaces:
- expose wl_subcompositor global interface
- error checking on protocol calls
- associate a parent wl_surface to a sub-surface
- introduce the sub-surface role, which is exclusive
- an implementation of the wl_subsurface interface
- allow nesting of sub-surfaces
- proper surface transformation inheritance from parent to sub-surfaces
- two different modes of wl_surface.commit for sub-surfaces
- hook sub-surfaces up to repaint by modifying the repaint list code
Struct weston_subsurface is dynamically allocated. For sub-surfaces, it
is completely populated.
For parent surfaces, weston_subsurface acts only as a link for stacking
order purposes. The wl_resource is unused, parent_destroy_listener is
not registered, the transform is not linked, etc.
Sub-surfaces are not added directly into layers for display or input.
Instead, they are hooked up via the sub-surface list present in parent
weston_surface. This way sub-surfaces are inherently linked to the
parent surface, and cannot be displayed unless the parent is mapped,
too. This also eases restacking, as only the parent will be in a layer
list. Also, only the main surface should be subject to shell actions.
The surface list rebuilding in weston_output_repaint() is modified to
process sub-surface lists, if they are non-empty. The sub-surface list
always contains the parent, too, unless empty. The collection of
frame_callback_list is moved to a later loop, to streamline the surface
list rebuild functions.
Features still lacking are:
- full-surface alpha support for compound windows
Changes in v2:
- fix a bug in surface mapping: commit a sub-surface would cause the
main surface to never be mapped.
- remove debug printfs
- detect attempt of making a surface its own parent
- always zero-alloc weston_subsurface
- apply wl_subsurface.set_position in commit, not immediately
- add weston_surface_to_subsurface()
- implement sub-surface commit modes parent-cached and independent
- implement wl_subcompositor.destroy and wl_subsurface.destroy
Changes in v3:
- rebased, and use the new transform inheritance code
- squashed the commit "add sub-surfaces to repaint list"
- fixed a buffer reference leak in commit_from_cache()
- Rewrite the sub-surface destructor code, and make it leave the
wl_subsurface protocol object inert, if one destroys the corresponding
wl_surface.
- replaced set_commit_mode with set_sync and set_desync
- allowed sub-surface nesting, and fixed repaint accordingly
- implemented nested sub-surface commit modes
- Made the sub-surface order changes from wl_subsurface.place_above and
.place_below to be applied when the parent surface state is applied,
instead of immediately. This conforms with the protocol specification
now.

frame_callback_list is moved to a later loop, to streamline the surface
list rebuild functions.
Features still lacking are:
- full-surface alpha support for compound windows
Changes in v2:
- fix a bug in surface mapping: commit a sub-surface would cause the
main surface to never be mapped.
- remove debug printfs
- detect attempt of making a surface its own parent
- always zero-alloc weston_subsurface
- apply wl_subsurface.set_position in commit, not immediately
- add weston_surface_to_subsurface()
- implement sub-surface commit modes parent-cached and independent
- implement wl_subcompositor.destroy and wl_subsurface.destroy
Changes in v3:
- rebased, and use the new transform inheritance code
- squashed the commit "add sub-surfaces to repaint list"
- fixed a buffer reference leak in commit_from_cache()
- Rewrite the sub-surface destructor code, and make it leave the
wl_subsurface protocol object inert, if one destroys the corresponding
wl_surface.
- replaced set_commit_mode with set_sync and set_desync
- allowed sub-surface nesting, and fixed repaint accordingly
- implemented nested sub-surface commit modes
- Made the sub-surface order changes from wl_subsurface.place_above and
.place_below to be applied when the parent surface state is applied,
instead of immediately. This conforms with the protocol specification
now.

compositor: introduce sub-surfaces
Implement the basic protocol for sub-surfaces:
- expose wl_subcompositor global interface
- error checking on protocol calls
- associate a parent wl_surface to a sub-surface
- introduce the sub-surface role, which is exclusive
- an implementation of the wl_subsurface interface
- allow nesting of sub-surfaces
- proper surface transformation inheritance from parent to sub-surfaces
- two different modes of wl_surface.commit for sub-surfaces
- hook sub-surfaces up to repaint by modifying the repaint list code
Struct weston_subsurface is dynamically allocated. For sub-surfaces, it
is completely populated.
For parent surfaces, weston_subsurface acts only as a link for stacking
order purposes. The wl_resource is unused, parent_destroy_listener is
not registered, the transform is not linked, etc.
Sub-surfaces are not added directly into layers for display or input.
Instead, they are hooked up via the sub-surface list present in parent
weston_surface. This way sub-surfaces are inherently linked to the
parent surface, and cannot be displayed unless the parent is mapped,
too. This also eases restacking, as only the parent will be in a layer
list. Also, only the main surface should be subject to shell actions.
The surface list rebuilding in weston_output_repaint() is modified to
process sub-surface lists, if they are non-empty. The sub-surface list
always contains the parent, too, unless empty. The collection of
frame_callback_list is moved to a later loop, to streamline the surface
list rebuild functions.
Features still lacking are:
- full-surface alpha support for compound windows
Changes in v2:
- fix a bug in surface mapping: commit a sub-surface would cause the
main surface to never be mapped.
- remove debug printfs
- detect attempt of making a surface its own parent
- always zero-alloc weston_subsurface
- apply wl_subsurface.set_position in commit, not immediately
- add weston_surface_to_subsurface()
- implement sub-surface commit modes parent-cached and independent
- implement wl_subcompositor.destroy and wl_subsurface.destroy
Changes in v3:
- rebased, and use the new transform inheritance code
- squashed the commit "add sub-surfaces to repaint list"
- fixed a buffer reference leak in commit_from_cache()
- Rewrite the sub-surface destructor code, and make it leave the
wl_subsurface protocol object inert, if one destroys the corresponding
wl_surface.
- replaced set_commit_mode with set_sync and set_desync
- allowed sub-surface nesting, and fixed repaint accordingly
- implemented nested sub-surface commit modes
- Made the sub-surface order changes from wl_subsurface.place_above and
.place_below to be applied when the parent surface state is applied,
instead of immediately. This conforms with the protocol specification

Split the geometry information from weston_surface out into weston_view
The weston_surface structure is split into two structures:
* The weston_surface structure storres everything required for a
client-side or server-side surface. This includes buffers; callbacks;
backend private data; input, damage, and opaque regions; and a few other
bookkeeping bits.
* The weston_view structure represents an entity in the scenegraph and
storres all of the geometry information. This includes clip region,
alpha, position, and the transformation list as well as all of the
temporary information derived from the geometry state. Because a view,
and not a surface, is a scenegraph element, the view is what is placed
in layers and planes.
There are a few things worth noting about the surface/view split:
1. This is *not* a modification to the protocol. It is, instead, a
modification to Weston's internal scenegraph to allow a single surface
to exist in multiple places at a time. Clients are completely unaware
of how many views to a particular surface exist.
2. A view is considered a direct child of a surface and is destroyed when
the surface is destroyed. Because of this, the view.surface pointer is
always valid and non-null.
3. The compositor's surface_list is replaced with a view_list. Due to
subsurfaces, building the view list is a little more complicated than
it used to be and involves building a tree of views on the fly whenever
subsurfaces are used. However, this means that backends can remain
completely subsurface-agnostic.
4. Surfaces and views both keep track of which outputs they are on.
5. The weston_surface structure now has width and height fields. These
are populated when a new buffer is attached before surface.configure
is called. This is because there are many surface-based operations
that really require the width and height and digging through the views
didn't work well.

compositor: Implement JSON-timeline logging
Logging is activated and deactivated with the debug key binding 't'.
When activated, it creates a new log file, where it records the events.
The log file contains events and detailed object information entries in
JSON format, and is meant to be parsed in sequence from beginning to the
end.
The emitted events are mostly related to the output repaint cycle, like
when repaint begins, is submitted to GPU, and when it completes on a
vblank. This is recorded per-output. Also some per-surface events are
recorded, including when surface damage is flushed.
To reduce the log size, events refer to objects like outputs and
surfaces by id numbers. Detailed object information is emitted only as
needed: on the first object occurrence, and afterwards only if
weston_timeline_object::force_refresh asks for it.
The detailed information for surfaces includes the string returned by
weston_surface::get_label. Therefore it is important to set
weston_timeline_object::force_refresh = 1 whenever the string would
change, so that the new details get recorded.
A rudimentary parser and SVG generator can be found at:
https://github.com/ppaalanen/wesgr
The timeline logs can answer questions including:
- How does the compositor repaint cycle work timing-wise?
- When was the vblank deadline missed?
- What is the latency from surface commit to showing the new content on
screen?
- How long does it take to process the scenegraph?
v2: weston_surface::get_description renamed to get_label.
v3: reafctor a bit into fprint_quoted_string().

Split the geometry information from weston_surface out into weston_view
The weston_surface structure is split into two structures:
* The weston_surface structure storres everything required for a
client-side or server-side surface. This includes buffers; callbacks;
backend private data; input, damage, and opaque regions; and a few other
bookkeeping bits.
* The weston_view structure represents an entity in the scenegraph and
storres all of the geometry information. This includes clip region,
alpha, position, and the transformation list as well as all of the
temporary information derived from the geometry state. Because a view,
and not a surface, is a scenegraph element, the view is what is placed
in layers and planes.
There are a few things worth noting about the surface/view split:
1. This is *not* a modification to the protocol. It is, instead, a
modification to Weston's internal scenegraph to allow a single surface
to exist in multiple places at a time. Clients are completely unaware
of how many views to a particular surface exist.
2. A view is considered a direct child of a surface and is destroyed when
the surface is destroyed. Because of this, the view.surface pointer is
always valid and non-null.
3. The compositor's surface_list is replaced with a view_list. Due to
subsurfaces, building the view list is a little more complicated than
it used to be and involves building a tree of views on the fly whenever
subsurfaces are used. However, this means that backends can remain
completely subsurface-agnostic.
4. Surfaces and views both keep track of which outputs they are on.
5. The weston_surface structure now has width and height fields. These
are populated when a new buffer is attached before surface.configure
is called. This is because there are many surface-based operations
that really require the width and height and digging through the views
didn't work well.

compositor: introduce sub-surfaces
Implement the basic protocol for sub-surfaces:
- expose wl_subcompositor global interface
- error checking on protocol calls
- associate a parent wl_surface to a sub-surface
- introduce the sub-surface role, which is exclusive
- an implementation of the wl_subsurface interface
- allow nesting of sub-surfaces
- proper surface transformation inheritance from parent to sub-surfaces
- two different modes of wl_surface.commit for sub-surfaces
- hook sub-surfaces up to repaint by modifying the repaint list code
Struct weston_subsurface is dynamically allocated. For sub-surfaces, it
is completely populated.
For parent surfaces, weston_subsurface acts only as a link for stacking
order purposes. The wl_resource is unused, parent_destroy_listener is
not registered, the transform is not linked, etc.
Sub-surfaces are not added directly into layers for display or input.
Instead, they are hooked up via the sub-surface list present in parent
weston_surface. This way sub-surfaces are inherently linked to the
parent surface, and cannot be displayed unless the parent is mapped,
too. This also eases restacking, as only the parent will be in a layer
list. Also, only the main surface should be subject to shell actions.
The surface list rebuilding in weston_output_repaint() is modified to
process sub-surface lists, if they are non-empty. The sub-surface list
always contains the parent, too, unless empty. The collection of
frame_callback_list is moved to a later loop, to streamline the surface
list rebuild functions.
Features still lacking are:
- full-surface alpha support for compound windows
Changes in v2:
- fix a bug in surface mapping: commit a sub-surface would cause the
main surface to never be mapped.
- remove debug printfs
- detect attempt of making a surface its own parent
- always zero-alloc weston_subsurface
- apply wl_subsurface.set_position in commit, not immediately
- add weston_surface_to_subsurface()
- implement sub-surface commit modes parent-cached and independent
- implement wl_subcompositor.destroy and wl_subsurface.destroy
Changes in v3:
- rebased, and use the new transform inheritance code
- squashed the commit "add sub-surfaces to repaint list"
- fixed a buffer reference leak in commit_from_cache()
- Rewrite the sub-surface destructor code, and make it leave the
wl_subsurface protocol object inert, if one destroys the corresponding
wl_surface.
- replaced set_commit_mode with set_sync and set_desync
- allowed sub-surface nesting, and fixed repaint accordingly
- implemented nested sub-surface commit modes
- Made the sub-surface order changes from wl_subsurface.place_above and
.place_below to be applied when the parent surface state is applied,
instead of immediately. This conforms with the protocol specification
now.

Rename wayland-compositor to weston
This rename addresses a few problems around the split between core
Wayland and the wayland-demos repository.
1) Initially, we had one big repository with protocol code, sample
compositor and sample clients. We split that repository to make it
possible to implement the protocol without pulling in the sample/demo
code. At this point, the compositor is more than just a "demo" and
wayland-demos doesn't send the right message. The sample compositor
is a useful, self-contained project in it's own right, and we want to
move away from the "demos" label.
2) Another problem is that the wayland-demos compositor is often
called "the wayland compsitor", but it's really just one possible
compositor. Existing X11 compositors are expected to add Wayland
support and then gradually phase out/modularize the X11 support, for
example. Conversely, it's hard to talk about the wayland-demos
compositor specifically as opposed to, eg, the wayland protocol or a
wayland compositor in general.
We are also renaming the repo to weston, and the compositor
subdirectory to src/, to emphasize that the main "output" is the
compositor.

compositor: introduce sub-surfaces
Implement the basic protocol for sub-surfaces:
- expose wl_subcompositor global interface
- error checking on protocol calls
- associate a parent wl_surface to a sub-surface
- introduce the sub-surface role, which is exclusive
- an implementation of the wl_subsurface interface
- allow nesting of sub-surfaces
- proper surface transformation inheritance from parent to sub-surfaces
- two different modes of wl_surface.commit for sub-surfaces
- hook sub-surfaces up to repaint by modifying the repaint list code
Struct weston_subsurface is dynamically allocated. For sub-surfaces, it
is completely populated.
For parent surfaces, weston_subsurface acts only as a link for stacking
order purposes. The wl_resource is unused, parent_destroy_listener is
not registered, the transform is not linked, etc.
Sub-surfaces are not added directly into layers for display or input.
Instead, they are hooked up via the sub-surface list present in parent
weston_surface. This way sub-surfaces are inherently linked to the
parent surface, and cannot be displayed unless the parent is mapped,
too. This also eases restacking, as only the parent will be in a layer
list. Also, only the main surface should be subject to shell actions.
The surface list rebuilding in weston_output_repaint() is modified to
process sub-surface lists, if they are non-empty. The sub-surface list
always contains the parent, too, unless empty. The collection of
frame_callback_list is moved to a later loop, to streamline the surface
list rebuild functions.
Features still lacking are:
- full-surface alpha support for compound windows
Changes in v2:
- fix a bug in surface mapping: commit a sub-surface would cause the
main surface to never be mapped.
- remove debug printfs
- detect attempt of making a surface its own parent
- always zero-alloc weston_subsurface
- apply wl_subsurface.set_position in commit, not immediately
- add weston_surface_to_subsurface()
- implement sub-surface commit modes parent-cached and independent
- implement wl_subcompositor.destroy and wl_subsurface.destroy
Changes in v3:
- rebased, and use the new transform inheritance code
- squashed the commit "add sub-surfaces to repaint list"
- fixed a buffer reference leak in commit_from_cache()
- Rewrite the sub-surface destructor code, and make it leave the
wl_subsurface protocol object inert, if one destroys the corresponding
wl_surface.
- replaced set_commit_mode with set_sync and set_desync
- allowed sub-surface nesting, and fixed repaint accordingly
- implemented nested sub-surface commit modes
- Made the sub-surface order changes from wl_subsurface.place_above and
.place_below to be applied when the parent surface state is applied,
instead of immediately. This conforms with the protocol specification
now.

- rebased, and use the new transform inheritance code
- squashed the commit "add sub-surfaces to repaint list"
- fixed a buffer reference leak in commit_from_cache()
- Rewrite the sub-surface destructor code, and make it leave the
wl_subsurface protocol object inert, if one destroys the corresponding
wl_surface.
- replaced set_commit_mode with set_sync and set_desync
- allowed sub-surface nesting, and fixed repaint accordingly
- implemented nested sub-surface commit modes
- Made the sub-surface order changes from wl_subsurface.place_above and
.place_below to be applied when the parent surface state is applied,
instead of immediately. This conforms with the protocol specification
now.

compositor: introduce sub-surfaces
Implement the basic protocol for sub-surfaces:
- expose wl_subcompositor global interface
- error checking on protocol calls
- associate a parent wl_surface to a sub-surface
- introduce the sub-surface role, which is exclusive
- an implementation of the wl_subsurface interface
- allow nesting of sub-surfaces
- proper surface transformation inheritance from parent to sub-surfaces
- two different modes of wl_surface.commit for sub-surfaces
- hook sub-surfaces up to repaint by modifying the repaint list code
Struct weston_subsurface is dynamically allocated. For sub-surfaces, it
is completely populated.
For parent surfaces, weston_subsurface acts only as a link for stacking
order purposes. The wl_resource is unused, parent_destroy_listener is
not registered, the transform is not linked, etc.
Sub-surfaces are not added directly into layers for display or input.
Instead, they are hooked up via the sub-surface list present in parent
weston_surface. This way sub-surfaces are inherently linked to the
parent surface, and cannot be displayed unless the parent is mapped,
too. This also eases restacking, as only the parent will be in a layer
list. Also, only the main surface should be subject to shell actions.
The surface list rebuilding in weston_output_repaint() is modified to
process sub-surface lists, if they are non-empty. The sub-surface list
always contains the parent, too, unless empty. The collection of
frame_callback_list is moved to a later loop, to streamline the surface
list rebuild functions.
Features still lacking are:
- full-surface alpha support for compound windows
Changes in v2:
- fix a bug in surface mapping: commit a sub-surface would cause the
main surface to never be mapped.
- remove debug printfs
- detect attempt of making a surface its own parent
- always zero-alloc weston_subsurface
- apply wl_subsurface.set_position in commit, not immediately
- add weston_surface_to_subsurface()
- implement sub-surface commit modes parent-cached and independent
- implement wl_subcompositor.destroy and wl_subsurface.destroy

- squashed the commit "add sub-surfaces to repaint list"
- fixed a buffer reference leak in commit_from_cache()
- Rewrite the sub-surface destructor code, and make it leave the
wl_subsurface protocol object inert, if one destroys the corresponding
wl_surface.
- replaced set_commit_mode with set_sync and set_desync
- allowed sub-surface nesting, and fixed repaint accordingly
- implemented nested sub-surface commit modes
- Made the sub-surface order changes from wl_subsurface.place_above and
.place_below to be applied when the parent surface state is applied,
instead of immediately. This conforms with the protocol specification
now.

Split the geometry information from weston_surface out into weston_view
The weston_surface structure is split into two structures:
* The weston_surface structure storres everything required for a
client-side or server-side surface. This includes buffers; callbacks;
backend private data; input, damage, and opaque regions; and a few other
bookkeeping bits.
* The weston_view structure represents an entity in the scenegraph and
storres all of the geometry information. This includes clip region,
alpha, position, and the transformation list as well as all of the
temporary information derived from the geometry state. Because a view,
and not a surface, is a scenegraph element, the view is what is placed
in layers and planes.
There are a few things worth noting about the surface/view split:
1. This is *not* a modification to the protocol. It is, instead, a
modification to Weston's internal scenegraph to allow a single surface
to exist in multiple places at a time. Clients are completely unaware
of how many views to a particular surface exist.
2. A view is considered a direct child of a surface and is destroyed when
the surface is destroyed. Because of this, the view.surface pointer is
always valid and non-null.
3. The compositor's surface_list is replaced with a view_list. Due to
subsurfaces, building the view list is a little more complicated than
it used to be and involves building a tree of views on the fly whenever
subsurfaces are used. However, this means that backends can remain
completely subsurface-agnostic.
4. Surfaces and views both keep track of which outputs they are on.
5. The weston_surface structure now has width and height fields. These
are populated when a new buffer is attached before surface.configure
is called. This is because there are many surface-based operations
that really require the width and height and digging through the views
didn't work well.

compositor: add weston_surface_set_label_func()
When printing out logs from Weston's actions, mainly for debugging, it
can be very difficult to identify the different surfaces. Inspecting
the configure function pointer is not useful, as the configure functions
may live in modules.
Add vfunc get_label to weston_surface, which will produce a short,
human-readable description of the surface, which allows identifying it
better, rather than just looking at the surface size, for instance.
Set the label function from most parts of Weston, to identify cursors and
drag icons, and panels, backgrounds, screensavers and lock surfaces, and
the desktop shell's application surfaces.
v2: renamed 'description' to 'label', so we get
weston_surface_set_label_func().

compositor: introduce sub-surfaces
Implement the basic protocol for sub-surfaces:
- expose wl_subcompositor global interface
- error checking on protocol calls
- associate a parent wl_surface to a sub-surface
- introduce the sub-surface role, which is exclusive
- an implementation of the wl_subsurface interface
- allow nesting of sub-surfaces
- proper surface transformation inheritance from parent to sub-surfaces
- two different modes of wl_surface.commit for sub-surfaces
- hook sub-surfaces up to repaint by modifying the repaint list code
Struct weston_subsurface is dynamically allocated. For sub-surfaces, it
is completely populated.
For parent surfaces, weston_subsurface acts only as a link for stacking
order purposes. The wl_resource is unused, parent_destroy_listener is
not registered, the transform is not linked, etc.
Sub-surfaces are not added directly into layers for display or input.
Instead, they are hooked up via the sub-surface list present in parent
weston_surface. This way sub-surfaces are inherently linked to the
parent surface, and cannot be displayed unless the parent is mapped,
too. This also eases restacking, as only the parent will be in a layer
list. Also, only the main surface should be subject to shell actions.
The surface list rebuilding in weston_output_repaint() is modified to
process sub-surface lists, if they are non-empty. The sub-surface list
always contains the parent, too, unless empty. The collection of
frame_callback_list is moved to a later loop, to streamline the surface
list rebuild functions.
Features still lacking are:
- full-surface alpha support for compound windows
Changes in v2:
- fix a bug in surface mapping: commit a sub-surface would cause the
main surface to never be mapped.
- remove debug printfs
- detect attempt of making a surface its own parent
- always zero-alloc weston_subsurface
- apply wl_subsurface.set_position in commit, not immediately
- add weston_surface_to_subsurface()
- implement sub-surface commit modes parent-cached and independent
- implement wl_subcompositor.destroy and wl_subsurface.destroy
Changes in v3:

compositor: quick fix for sub-surface mapping
If a client does this:
1. create a main window and map it
2. create a wl_surface, and make it a sub-surface of the main window
3. set the sub-surface to desync
4. commit content to the sub-surface to map it
Then step 4 should cause the sub-surface to become mapped. However,
Weston fails to schedule a repaint in that case, so the sub-surface will
not appear until something else causes a repaint on that output, e.g.
the main window.
A quick and dirty fix is to set the output mask for the surface in
Weston, which allows the repaint to be scheduled. This patch implements
that, and might only work right on single-output systems.
A proper fix would involve rewriting the whole "is surface mapped"
mechanism in Weston, to not rely on output assignments but to have a
separate flag for "mapped", and figuring out how to schedule repaints
for the right outputs.
Following is the actual protocol sequence used to trigger the problem:
[3224648.125] -> wl_compositor@4.create_surface(new id wl_surface@3)
[3224648.206] -> xdg_shell@7.get_xdg_surface(new id xdg_surface@8, wl_surface@3)

[3224650.244] -> wl_shm_pool@9.destroy()
[3224651.975] -> wl_surface@3.attach(wl_buffer@10, 0, 0)
[3224652.100] -> wl_surface@3.damage(20, 20, 210, 210)

compositor: introduce sub-surfaces
Implement the basic protocol for sub-surfaces:
- expose wl_subcompositor global interface
- error checking on protocol calls
- associate a parent wl_surface to a sub-surface
- introduce the sub-surface role, which is exclusive
- an implementation of the wl_subsurface interface
- allow nesting of sub-surfaces
- proper surface transformation inheritance from parent to sub-surfaces
- two different modes of wl_surface.commit for sub-surfaces
- hook sub-surfaces up to repaint by modifying the repaint list code
Struct weston_subsurface is dynamically allocated. For sub-surfaces, it
is completely populated.
For parent surfaces, weston_subsurface acts only as a link for stacking
order purposes. The wl_resource is unused, parent_destroy_listener is
not registered, the transform is not linked, etc.
Sub-surfaces are not added directly into layers for display or input.
Instead, they are hooked up via the sub-surface list present in parent
weston_surface. This way sub-surfaces are inherently linked to the
parent surface, and cannot be displayed unless the parent is mapped,
too. This also eases restacking, as only the parent will be in a layer
list. Also, only the main surface should be subject to shell actions.
The surface list rebuilding in weston_output_repaint() is modified to
process sub-surface lists, if they are non-empty. The sub-surface list
always contains the parent, too, unless empty. The collection of
frame_callback_list is moved to a later loop, to streamline the surface
list rebuild functions.
Features still lacking are:
- full-surface alpha support for compound windows
Changes in v2:
- fix a bug in surface mapping: commit a sub-surface would cause the
main surface to never be mapped.
- remove debug printfs
- detect attempt of making a surface its own parent
- always zero-alloc weston_subsurface
- apply wl_subsurface.set_position in commit, not immediately
- add weston_surface_to_subsurface()
- implement sub-surface commit modes parent-cached and independent
- implement wl_subcompositor.destroy and wl_subsurface.destroy
Changes in v3:
- rebased, and use the new transform inheritance code
- squashed the commit "add sub-surfaces to repaint list"
- fixed a buffer reference leak in commit_from_cache()
- Rewrite the sub-surface destructor code, and make it leave the
wl_subsurface protocol object inert, if one destroys the corresponding
wl_surface.
- replaced set_commit_mode with set_sync and set_desync
- allowed sub-surface nesting, and fixed repaint accordingly
- implemented nested sub-surface commit modes
- Made the sub-surface order changes from wl_subsurface.place_above and
.place_below to be applied when the parent surface state is applied,
instead of immediately. This conforms with the protocol specification
now.

compositor: quick fix for sub-surface mapping
If a client does this:
1. create a main window and map it
2. create a wl_surface, and make it a sub-surface of the main window
3. set the sub-surface to desync
4. commit content to the sub-surface to map it
Then step 4 should cause the sub-surface to become mapped. However,
Weston fails to schedule a repaint in that case, so the sub-surface will
not appear until something else causes a repaint on that output, e.g.
the main window.
A quick and dirty fix is to set the output mask for the surface in
Weston, which allows the repaint to be scheduled. This patch implements
that, and might only work right on single-output systems.
A proper fix would involve rewriting the whole "is surface mapped"
mechanism in Weston, to not rely on output assignments but to have a
separate flag for "mapped", and figuring out how to schedule repaints
for the right outputs.
Following is the actual protocol sequence used to trigger the problem:
[3224648.125] -> wl_compositor@4.create_surface(new id wl_surface@3)
[3224648.206] -> xdg_shell@7.get_xdg_surface(new id xdg_surface@8, wl_surface@3)

shell: keyboard focus and restacking fixes for sub-surfaces
The shell needs to redirect some actions to the parent surface, when
they originally target a sub-surface. This patch implements the
following:
- Move, resize, and rotate bindings always target the parent surface.
- Opacity (full-surface alpha) binding targets the parent surface. This
is broken, because it should change the opacity of the whole compound
window, which is difficult to implement in the renderer.
- click_to_activate_binding() needs to check the shell surface type from
the main surface, because sub-surface would produce SHELL_SURFACE_NONE
and prevent activation.
- Also activate() needs to check the type from the main surface, and
restack the main surface. Keyboard focus is assigned to the original
(sub-)surface.
- focus_state_surface_destroy() needs to handle sub-surfaces: only the
main surface will be in a layer list. If the destroyed surface is
indeed a sub-surface, activate the main surface next. This way a
client that destroys a focused sub-surface still retains focus in the
same window.
- The workspace_manager.move_surface request can accept also
sub-surfaces, and it will move the corresponding main surface.
Changes in v2:
- do not special-case keyboard focus for sub-surfaces
- fix surface type checks for sub-surfaces in shell, fix restacking of
sub-surfaces in shell, fix focus_state_surface_destroy()
Changes in v3:
- Renamed weston_surface_get_parent() to
weston_surface_get_main_surface() to be more explicit that this is
about sub-surfaces
- Fixed move_surface_to_workspace() to handle keyboard focus on a
sub-surface.
- Used a temporary variable in several places to clarify code, instead
of reassigning a variable.
- Fixed workspace_manager_move_surface() to deal with sub-surfaces.

compositor: send error for surface role resets
With the more accurate definition of wl_surface roles in Wayland,
enforce the restriction: a role is always set permanently, and
attempting to change it is a protocol error.
This patch is based on Jasper's patch:
http://lists.freedesktop.org/archives/wayland-devel/2014-August/016811.html
The difference in this patch compared to his are:
- send role errors on the interface whose request triggers it, not on
wl_surface
- an interface could have several requests assigning different roles,
cannot use wl_interface as the unique key; use an arbitary string
instead
- ensure in window-manager.c that create_shell_surface() ->
create_common_surface() is never called with surface->configure set,
to avoid compositor abort
- use wl_resource_post_no_memory() where appropriate instead of
hand-rolling it with wl_resource_post_error()
Ideally we would not add weston_surface::role_name field, but use
weston_surface::configure. At the moment this is not possible though,
because at least shell.c uses several different roles with the same
configure function. Drag'n'drop uses two configure functions for the
same role. The configure hook is also reset in several places,
which is not good for role tracking.
This patch overlooks the wl_surface roles assigned in privileged
extensions: screensaver, panel, background, lock, input panel.

compositor: add weston_surface_set_label_func()
When printing out logs from Weston's actions, mainly for debugging, it
can be very difficult to identify the different surfaces. Inspecting
the configure function pointer is not useful, as the configure functions
may live in modules.
Add vfunc get_label to weston_surface, which will produce a short,
human-readable description of the surface, which allows identifying it
better, rather than just looking at the surface size, for instance.
Set the label function from most parts of Weston, to identify cursors and
drag icons, and panels, backgrounds, screensavers and lock surfaces, and
the desktop shell's application surfaces.
v2: renamed 'description' to 'label', so we get
weston_surface_set_label_func().

compositor: Implement JSON-timeline logging
Logging is activated and deactivated with the debug key binding 't'.
When activated, it creates a new log file, where it records the events.
The log file contains events and detailed object information entries in
JSON format, and is meant to be parsed in sequence from beginning to the
end.
The emitted events are mostly related to the output repaint cycle, like
when repaint begins, is submitted to GPU, and when it completes on a
vblank. This is recorded per-output. Also some per-surface events are
recorded, including when surface damage is flushed.
To reduce the log size, events refer to objects like outputs and
surfaces by id numbers. Detailed object information is emitted only as
needed: on the first object occurrence, and afterwards only if
weston_timeline_object::force_refresh asks for it.
The detailed information for surfaces includes the string returned by
weston_surface::get_label. Therefore it is important to set
weston_timeline_object::force_refresh = 1 whenever the string would
change, so that the new details get recorded.
A rudimentary parser and SVG generator can be found at:
https://github.com/ppaalanen/wesgr
The timeline logs can answer questions including:
- How does the compositor repaint cycle work timing-wise?
- When was the vblank deadline missed?
- What is the latency from surface commit to showing the new content on
screen?
- How long does it take to process the scenegraph?
v2: weston_surface::get_description renamed to get_label.
v3: reafctor a bit into fprint_quoted_string().

compositor: introduce sub-surfaces
Implement the basic protocol for sub-surfaces:
- expose wl_subcompositor global interface
- error checking on protocol calls
- associate a parent wl_surface to a sub-surface
- introduce the sub-surface role, which is exclusive
- an implementation of the wl_subsurface interface
- allow nesting of sub-surfaces
- proper surface transformation inheritance from parent to sub-surfaces
- two different modes of wl_surface.commit for sub-surfaces
- hook sub-surfaces up to repaint by modifying the repaint list code
Struct weston_subsurface is dynamically allocated. For sub-surfaces, it
is completely populated.
For parent surfaces, weston_subsurface acts only as a link for stacking
order purposes. The wl_resource is unused, parent_destroy_listener is
not registered, the transform is not linked, etc.
Sub-surfaces are not added directly into layers for display or input.
Instead, they are hooked up via the sub-surface list present in parent
weston_surface. This way sub-surfaces are inherently linked to the
parent surface, and cannot be displayed unless the parent is mapped,
too. This also eases restacking, as only the parent will be in a layer
list. Also, only the main surface should be subject to shell actions.
The surface list rebuilding in weston_output_repaint() is modified to
process sub-surface lists, if they are non-empty. The sub-surface list
always contains the parent, too, unless empty. The collection of
frame_callback_list is moved to a later loop, to streamline the surface
list rebuild functions.
Features still lacking are:
- full-surface alpha support for compound windows
Changes in v2:
- fix a bug in surface mapping: commit a sub-surface would cause the
main surface to never be mapped.
- remove debug printfs
- detect attempt of making a surface its own parent
- always zero-alloc weston_subsurface
- apply wl_subsurface.set_position in commit, not immediately
- add weston_surface_to_subsurface()
- implement sub-surface commit modes parent-cached and independent
- implement wl_subcompositor.destroy and wl_subsurface.destroy
Changes in v3:
- rebased, and use the new transform inheritance code
- squashed the commit "add sub-surfaces to repaint list"
- fixed a buffer reference leak in commit_from_cache()
- Rewrite the sub-surface destructor code, and make it leave the
wl_subsurface protocol object inert, if one destroys the corresponding
wl_surface.
- replaced set_commit_mode with set_sync and set_desync
- allowed sub-surface nesting, and fixed repaint accordingly
- implemented nested sub-surface commit modes
- Made the sub-surface order changes from wl_subsurface.place_above and
.place_below to be applied when the parent surface state is applied,
instead of immediately. This conforms with the protocol specification
now.

- apply wl_subsurface.set_position in commit, not immediately
- add weston_surface_to_subsurface()
- implement sub-surface commit modes parent-cached and independent
- implement wl_subcompositor.destroy and wl_subsurface.destroy
Changes in v3:
- rebased, and use the new transform inheritance code
- squashed the commit "add sub-surfaces to repaint list"
- fixed a buffer reference leak in commit_from_cache()
- Rewrite the sub-surface destructor code, and make it leave the
wl_subsurface protocol object inert, if one destroys the corresponding
wl_surface.
- replaced set_commit_mode with set_sync and set_desync
- allowed sub-surface nesting, and fixed repaint accordingly
- implemented nested sub-surface commit modes
- Made the sub-surface order changes from wl_subsurface.place_above and
.place_below to be applied when the parent surface state is applied,
instead of immediately. This conforms with the protocol specification
now.

compositor: introduce sub-surfaces
Implement the basic protocol for sub-surfaces:
- expose wl_subcompositor global interface
- error checking on protocol calls
- associate a parent wl_surface to a sub-surface
- introduce the sub-surface role, which is exclusive
- an implementation of the wl_subsurface interface
- allow nesting of sub-surfaces
- proper surface transformation inheritance from parent to sub-surfaces
- two different modes of wl_surface.commit for sub-surfaces
- hook sub-surfaces up to repaint by modifying the repaint list code
Struct weston_subsurface is dynamically allocated. For sub-surfaces, it
is completely populated.
For parent surfaces, weston_subsurface acts only as a link for stacking
order purposes. The wl_resource is unused, parent_destroy_listener is
not registered, the transform is not linked, etc.
Sub-surfaces are not added directly into layers for display or input.
Instead, they are hooked up via the sub-surface list present in parent
weston_surface. This way sub-surfaces are inherently linked to the
parent surface, and cannot be displayed unless the parent is mapped,
too. This also eases restacking, as only the parent will be in a layer
list. Also, only the main surface should be subject to shell actions.
The surface list rebuilding in weston_output_repaint() is modified to
process sub-surface lists, if they are non-empty. The sub-surface list
always contains the parent, too, unless empty. The collection of
frame_callback_list is moved to a later loop, to streamline the surface
list rebuild functions.
Features still lacking are:
- full-surface alpha support for compound windows
Changes in v2:
- fix a bug in surface mapping: commit a sub-surface would cause the
main surface to never be mapped.
- remove debug printfs
- detect attempt of making a surface its own parent
- always zero-alloc weston_subsurface
- apply wl_subsurface.set_position in commit, not immediately
- add weston_surface_to_subsurface()
- implement sub-surface commit modes parent-cached and independent

compositor: introduce sub-surfaces
Implement the basic protocol for sub-surfaces:
- expose wl_subcompositor global interface
- error checking on protocol calls
- associate a parent wl_surface to a sub-surface
- introduce the sub-surface role, which is exclusive
- an implementation of the wl_subsurface interface
- allow nesting of sub-surfaces
- proper surface transformation inheritance from parent to sub-surfaces
- two different modes of wl_surface.commit for sub-surfaces
- hook sub-surfaces up to repaint by modifying the repaint list code
Struct weston_subsurface is dynamically allocated. For sub-surfaces, it
is completely populated.
For parent surfaces, weston_subsurface acts only as a link for stacking
order purposes. The wl_resource is unused, parent_destroy_listener is
not registered, the transform is not linked, etc.
Sub-surfaces are not added directly into layers for display or input.
Instead, they are hooked up via the sub-surface list present in parent
weston_surface. This way sub-surfaces are inherently linked to the
parent surface, and cannot be displayed unless the parent is mapped,
too. This also eases restacking, as only the parent will be in a layer
list. Also, only the main surface should be subject to shell actions.
The surface list rebuilding in weston_output_repaint() is modified to
process sub-surface lists, if they are non-empty. The sub-surface list
always contains the parent, too, unless empty. The collection of
frame_callback_list is moved to a later loop, to streamline the surface
list rebuild functions.
Features still lacking are:
- full-surface alpha support for compound windows
Changes in v2:
- fix a bug in surface mapping: commit a sub-surface would cause the
main surface to never be mapped.
- remove debug printfs
- detect attempt of making a surface its own parent
- always zero-alloc weston_subsurface
- apply wl_subsurface.set_position in commit, not immediately
- add weston_surface_to_subsurface()

Split the geometry information from weston_surface out into weston_view
The weston_surface structure is split into two structures:
* The weston_surface structure storres everything required for a
client-side or server-side surface. This includes buffers; callbacks;
backend private data; input, damage, and opaque regions; and a few other
bookkeeping bits.
* The weston_view structure represents an entity in the scenegraph and
storres all of the geometry information. This includes clip region,
alpha, position, and the transformation list as well as all of the
temporary information derived from the geometry state. Because a view,
and not a surface, is a scenegraph element, the view is what is placed
in layers and planes.
There are a few things worth noting about the surface/view split:
1. This is *not* a modification to the protocol. It is, instead, a
modification to Weston's internal scenegraph to allow a single surface
to exist in multiple places at a time. Clients are completely unaware
of how many views to a particular surface exist.
2. A view is considered a direct child of a surface and is destroyed when
the surface is destroyed. Because of this, the view.surface pointer is
always valid and non-null.
3. The compositor's surface_list is replaced with a view_list. Due to
subsurfaces, building the view list is a little more complicated than
it used to be and involves building a tree of views on the fly whenever
subsurfaces are used. However, this means that backends can remain
completely subsurface-agnostic.
4. Surfaces and views both keep track of which outputs they are on.
5. The weston_surface structure now has width and height fields. These
are populated when a new buffer is attached before surface.configure
is called. This is because there are many surface-based operations
that really require the width and height and digging through the views
didn't work well.

in layers and planes.
There are a few things worth noting about the surface/view split:
1. This is *not* a modification to the protocol. It is, instead, a
modification to Weston's internal scenegraph to allow a single surface
to exist in multiple places at a time. Clients are completely unaware
of how many views to a particular surface exist.
2. A view is considered a direct child of a surface and is destroyed when
the surface is destroyed. Because of this, the view.surface pointer is
always valid and non-null.
3. The compositor's surface_list is replaced with a view_list. Due to
subsurfaces, building the view list is a little more complicated than
it used to be and involves building a tree of views on the fly whenever
subsurfaces are used. However, this means that backends can remain
completely subsurface-agnostic.
4. Surfaces and views both keep track of which outputs they are on.
5. The weston_surface structure now has width and height fields. These
are populated when a new buffer is attached before surface.configure
is called. This is because there are many surface-based operations
that really require the width and height and digging through the views
didn't work well.

Split the geometry information from weston_surface out into weston_view
The weston_surface structure is split into two structures:
* The weston_surface structure storres everything required for a
client-side or server-side surface. This includes buffers; callbacks;
backend private data; input, damage, and opaque regions; and a few other
bookkeeping bits.
* The weston_view structure represents an entity in the scenegraph and
storres all of the geometry information. This includes clip region,
alpha, position, and the transformation list as well as all of the
temporary information derived from the geometry state. Because a view,
and not a surface, is a scenegraph element, the view is what is placed
in layers and planes.

compositor: introduce sub-surfaces
Implement the basic protocol for sub-surfaces:
- expose wl_subcompositor global interface
- error checking on protocol calls
- associate a parent wl_surface to a sub-surface
- introduce the sub-surface role, which is exclusive
- an implementation of the wl_subsurface interface
- allow nesting of sub-surfaces
- proper surface transformation inheritance from parent to sub-surfaces
- two different modes of wl_surface.commit for sub-surfaces
- hook sub-surfaces up to repaint by modifying the repaint list code
Struct weston_subsurface is dynamically allocated. For sub-surfaces, it
is completely populated.
For parent surfaces, weston_subsurface acts only as a link for stacking
order purposes. The wl_resource is unused, parent_destroy_listener is
not registered, the transform is not linked, etc.
Sub-surfaces are not added directly into layers for display or input.
Instead, they are hooked up via the sub-surface list present in parent
weston_surface. This way sub-surfaces are inherently linked to the
parent surface, and cannot be displayed unless the parent is mapped,
too. This also eases restacking, as only the parent will be in a layer
list. Also, only the main surface should be subject to shell actions.
The surface list rebuilding in weston_output_repaint() is modified to
process sub-surface lists, if they are non-empty. The sub-surface list
always contains the parent, too, unless empty. The collection of
frame_callback_list is moved to a later loop, to streamline the surface
list rebuild functions.
Features still lacking are:
- full-surface alpha support for compound windows
Changes in v2:
- fix a bug in surface mapping: commit a sub-surface would cause the
main surface to never be mapped.
- remove debug printfs
- detect attempt of making a surface its own parent
- always zero-alloc weston_subsurface
- apply wl_subsurface.set_position in commit, not immediately
- add weston_surface_to_subsurface()
- implement sub-surface commit modes parent-cached and independent
- implement wl_subcompositor.destroy and wl_subsurface.destroy
Changes in v3:
- rebased, and use the new transform inheritance code
- squashed the commit "add sub-surfaces to repaint list"
- fixed a buffer reference leak in commit_from_cache()
- Rewrite the sub-surface destructor code, and make it leave the
wl_subsurface protocol object inert, if one destroys the corresponding
wl_surface.
- replaced set_commit_mode with set_sync and set_desync
- allowed sub-surface nesting, and fixed repaint accordingly
- implemented nested sub-surface commit modes
- Made the sub-surface order changes from wl_subsurface.place_above and
.place_below to be applied when the parent surface state is applied,
instead of immediately. This conforms with the protocol specification
now.

compositor: add weston_surface_set_label_func()
When printing out logs from Weston's actions, mainly for debugging, it
can be very difficult to identify the different surfaces. Inspecting
the configure function pointer is not useful, as the configure functions
may live in modules.
Add vfunc get_label to weston_surface, which will produce a short,
human-readable description of the surface, which allows identifying it
better, rather than just looking at the surface size, for instance.
Set the label function from most parts of Weston, to identify cursors and
drag icons, and panels, backgrounds, screensavers and lock surfaces, and
the desktop shell's application surfaces.
v2: renamed 'description' to 'label', so we get
weston_surface_set_label_func().

not registered, the transform is not linked, etc.
Sub-surfaces are not added directly into layers for display or input.
Instead, they are hooked up via the sub-surface list present in parent
weston_surface. This way sub-surfaces are inherently linked to the
parent surface, and cannot be displayed unless the parent is mapped,
too. This also eases restacking, as only the parent will be in a layer
list. Also, only the main surface should be subject to shell actions.
The surface list rebuilding in weston_output_repaint() is modified to
process sub-surface lists, if they are non-empty. The sub-surface list
always contains the parent, too, unless empty. The collection of
frame_callback_list is moved to a later loop, to streamline the surface
list rebuild functions.
Features still lacking are:
- full-surface alpha support for compound windows
Changes in v2:
- fix a bug in surface mapping: commit a sub-surface would cause the
main surface to never be mapped.
- remove debug printfs
- detect attempt of making a surface its own parent
- always zero-alloc weston_subsurface
- apply wl_subsurface.set_position in commit, not immediately
- add weston_surface_to_subsurface()
- implement sub-surface commit modes parent-cached and independent
- implement wl_subcompositor.destroy and wl_subsurface.destroy
Changes in v3:
- rebased, and use the new transform inheritance code
- squashed the commit "add sub-surfaces to repaint list"
- fixed a buffer reference leak in commit_from_cache()
- Rewrite the sub-surface destructor code, and make it leave the
wl_subsurface protocol object inert, if one destroys the corresponding
wl_surface.
- replaced set_commit_mode with set_sync and set_desync
- allowed sub-surface nesting, and fixed repaint accordingly
- implemented nested sub-surface commit modes
- Made the sub-surface order changes from wl_subsurface.place_above and
.place_below to be applied when the parent surface state is applied,
instead of immediately. This conforms with the protocol specification
now.

compositor: send error for surface role resets
With the more accurate definition of wl_surface roles in Wayland,
enforce the restriction: a role is always set permanently, and
attempting to change it is a protocol error.
This patch is based on Jasper's patch:
http://lists.freedesktop.org/archives/wayland-devel/2014-August/016811.html
The difference in this patch compared to his are:
- send role errors on the interface whose request triggers it, not on
wl_surface
- an interface could have several requests assigning different roles,
cannot use wl_interface as the unique key; use an arbitary string
instead
- ensure in window-manager.c that create_shell_surface() ->
create_common_surface() is never called with surface->configure set,
to avoid compositor abort
- use wl_resource_post_no_memory() where appropriate instead of
hand-rolling it with wl_resource_post_error()
Ideally we would not add weston_surface::role_name field, but use
weston_surface::configure. At the moment this is not possible though,
because at least shell.c uses several different roles with the same
configure function. Drag'n'drop uses two configure functions for the
same role. The configure hook is also reset in several places,
which is not good for role tracking.
This patch overlooks the wl_surface roles assigned in privileged
extensions: screensaver, panel, background, lock, input panel.

compositor: add weston_surface_set_label_func()
When printing out logs from Weston's actions, mainly for debugging, it
can be very difficult to identify the different surfaces. Inspecting
the configure function pointer is not useful, as the configure functions
may live in modules.
Add vfunc get_label to weston_surface, which will produce a short,
human-readable description of the surface, which allows identifying it
better, rather than just looking at the surface size, for instance.
Set the label function from most parts of Weston, to identify cursors and
drag icons, and panels, backgrounds, screensavers and lock surfaces, and
the desktop shell's application surfaces.
v2: renamed 'description' to 'label', so we get
weston_surface_set_label_func().

compositor: introduce sub-surfaces
Implement the basic protocol for sub-surfaces:
- expose wl_subcompositor global interface
- error checking on protocol calls
- associate a parent wl_surface to a sub-surface
- introduce the sub-surface role, which is exclusive
- an implementation of the wl_subsurface interface
- allow nesting of sub-surfaces
- proper surface transformation inheritance from parent to sub-surfaces
- two different modes of wl_surface.commit for sub-surfaces
- hook sub-surfaces up to repaint by modifying the repaint list code
Struct weston_subsurface is dynamically allocated. For sub-surfaces, it
is completely populated.
For parent surfaces, weston_subsurface acts only as a link for stacking
order purposes. The wl_resource is unused, parent_destroy_listener is
not registered, the transform is not linked, etc.
Sub-surfaces are not added directly into layers for display or input.
Instead, they are hooked up via the sub-surface list present in parent
weston_surface. This way sub-surfaces are inherently linked to the
parent surface, and cannot be displayed unless the parent is mapped,
too. This also eases restacking, as only the parent will be in a layer
list. Also, only the main surface should be subject to shell actions.
The surface list rebuilding in weston_output_repaint() is modified to
process sub-surface lists, if they are non-empty. The sub-surface list
always contains the parent, too, unless empty. The collection of
frame_callback_list is moved to a later loop, to streamline the surface
list rebuild functions.
Features still lacking are:
- full-surface alpha support for compound windows
Changes in v2:
- fix a bug in surface mapping: commit a sub-surface would cause the
main surface to never be mapped.
- remove debug printfs
- detect attempt of making a surface its own parent
- always zero-alloc weston_subsurface
- apply wl_subsurface.set_position in commit, not immediately
- add weston_surface_to_subsurface()
- implement sub-surface commit modes parent-cached and independent
- implement wl_subcompositor.destroy and wl_subsurface.destroy
Changes in v3:
- rebased, and use the new transform inheritance code
- squashed the commit "add sub-surfaces to repaint list"
- fixed a buffer reference leak in commit_from_cache()
- Rewrite the sub-surface destructor code, and make it leave the
wl_subsurface protocol object inert, if one destroys the corresponding
wl_surface.
- replaced set_commit_mode with set_sync and set_desync
- allowed sub-surface nesting, and fixed repaint accordingly
- implemented nested sub-surface commit modes
- Made the sub-surface order changes from wl_subsurface.place_above and
.place_below to be applied when the parent surface state is applied,
instead of immediately. This conforms with the protocol specification
now.

Rename wayland-compositor to weston
This rename addresses a few problems around the split between core
Wayland and the wayland-demos repository.
1) Initially, we had one big repository with protocol code, sample
compositor and sample clients. We split that repository to make it
possible to implement the protocol without pulling in the sample/demo
code. At this point, the compositor is more than just a "demo" and
wayland-demos doesn't send the right message. The sample compositor
is a useful, self-contained project in it's own right, and we want to
move away from the "demos" label.
2) Another problem is that the wayland-demos compositor is often
called "the wayland compsitor", but it's really just one possible
compositor. Existing X11 compositors are expected to add Wayland
support and then gradually phase out/modularize the X11 support, for
example. Conversely, it's hard to talk about the wayland-demos
compositor specifically as opposed to, eg, the wayland protocol or a
wayland compositor in general.
We are also renaming the repo to weston, and the compositor
subdirectory to src/, to emphasize that the main "output" is the
compositor.

compositor: Move fade animation out of core Weston into shell
Previously, it was impossible to override the fade in/out behavior of
Weston using a different shell, since this was implemented in core
Weston. This also led to complicated interaction between the shell and
the core when displaying lock surfaces and screensavers.
This patch starts to solve this issue by moving the fade animation out
of the core. On compositor.c, besides deleting the fade code, the idle
handler had to be changed to emit the lock signal, since it was called
from the fade_frame() function before. This causes a slight change of
behavior, since before the fade would happen with the compositor being
active, while now it is already in the idle state. That leads to the
dpms state being set when cancelling the fade with mouse movement, and
in turn, to a slight freeze with drm compositor. This problem will be
fixed in a follow up patch.
On the shell side, the fade was re-implemented in a slightly different
manner. Instead of using a custom frame function, the fade animation
from animation.c is used. The interface for starting the fade was also
changed to take the value of an enum instead of a float alpha value,
in order to improve readability.

Rename wayland-compositor to weston
This rename addresses a few problems around the split between core
Wayland and the wayland-demos repository.
1) Initially, we had one big repository with protocol code, sample
compositor and sample clients. We split that repository to make it
possible to implement the protocol without pulling in the sample/demo
code. At this point, the compositor is more than just a "demo" and
wayland-demos doesn't send the right message. The sample compositor
is a useful, self-contained project in it's own right, and we want to
move away from the "demos" label.
2) Another problem is that the wayland-demos compositor is often
called "the wayland compsitor", but it's really just one possible
compositor. Existing X11 compositors are expected to add Wayland
support and then gradually phase out/modularize the X11 support, for
example. Conversely, it's hard to talk about the wayland-demos
compositor specifically as opposed to, eg, the wayland protocol or a
wayland compositor in general.
We are also renaming the repo to weston, and the compositor
subdirectory to src/, to emphasize that the main "output" is the
compositor.

Split the geometry information from weston_surface out into weston_view
The weston_surface structure is split into two structures:
* The weston_surface structure storres everything required for a
client-side or server-side surface. This includes buffers; callbacks;
backend private data; input, damage, and opaque regions; and a few other
bookkeeping bits.
* The weston_view structure represents an entity in the scenegraph and
storres all of the geometry information. This includes clip region,
alpha, position, and the transformation list as well as all of the
temporary information derived from the geometry state. Because a view,
and not a surface, is a scenegraph element, the view is what is placed
in layers and planes.
There are a few things worth noting about the surface/view split:
1. This is *not* a modification to the protocol. It is, instead, a
modification to Weston's internal scenegraph to allow a single surface
to exist in multiple places at a time. Clients are completely unaware
of how many views to a particular surface exist.
2. A view is considered a direct child of a surface and is destroyed when
the surface is destroyed. Because of this, the view.surface pointer is
always valid and non-null.
3. The compositor's surface_list is replaced with a view_list. Due to
subsurfaces, building the view list is a little more complicated than
it used to be and involves building a tree of views on the fly whenever
subsurfaces are used. However, this means that backends can remain
completely subsurface-agnostic.
4. Surfaces and views both keep track of which outputs they are on.
5. The weston_surface structure now has width and height fields. These
are populated when a new buffer is attached before surface.configure
is called. This is because there are many surface-based operations
that really require the width and height and digging through the views
didn't work well.

Rename wayland-compositor to weston
This rename addresses a few problems around the split between core
Wayland and the wayland-demos repository.
1) Initially, we had one big repository with protocol code, sample
compositor and sample clients. We split that repository to make it
possible to implement the protocol without pulling in the sample/demo
code. At this point, the compositor is more than just a "demo" and
wayland-demos doesn't send the right message. The sample compositor
is a useful, self-contained project in it's own right, and we want to
move away from the "demos" label.
2) Another problem is that the wayland-demos compositor is often
called "the wayland compsitor", but it's really just one possible
compositor. Existing X11 compositors are expected to add Wayland
support and then gradually phase out/modularize the X11 support, for
example. Conversely, it's hard to talk about the wayland-demos
compositor specifically as opposed to, eg, the wayland protocol or a
wayland compositor in general.
We are also renaming the repo to weston, and the compositor
subdirectory to src/, to emphasize that the main "output" is the
compositor.

compositor: Implement JSON-timeline logging
Logging is activated and deactivated with the debug key binding 't'.
When activated, it creates a new log file, where it records the events.
The log file contains events and detailed object information entries in
JSON format, and is meant to be parsed in sequence from beginning to the
end.
The emitted events are mostly related to the output repaint cycle, like
when repaint begins, is submitted to GPU, and when it completes on a
vblank. This is recorded per-output. Also some per-surface events are
recorded, including when surface damage is flushed.
To reduce the log size, events refer to objects like outputs and
surfaces by id numbers. Detailed object information is emitted only as
needed: on the first object occurrence, and afterwards only if
weston_timeline_object::force_refresh asks for it.
The detailed information for surfaces includes the string returned by
weston_surface::get_label. Therefore it is important to set
weston_timeline_object::force_refresh = 1 whenever the string would
change, so that the new details get recorded.
A rudimentary parser and SVG generator can be found at:
https://github.com/ppaalanen/wesgr
The timeline logs can answer questions including:
- How does the compositor repaint cycle work timing-wise?
- When was the vblank deadline missed?
- What is the latency from surface commit to showing the new content on
screen?
- How long does it take to process the scenegraph?
v2: weston_surface::get_description renamed to get_label.
v3: reafctor a bit into fprint_quoted_string().

compositor: introduce sub-surfaces
Implement the basic protocol for sub-surfaces:
- expose wl_subcompositor global interface
- error checking on protocol calls
- associate a parent wl_surface to a sub-surface
- introduce the sub-surface role, which is exclusive
- an implementation of the wl_subsurface interface
- allow nesting of sub-surfaces
- proper surface transformation inheritance from parent to sub-surfaces
- two different modes of wl_surface.commit for sub-surfaces
- hook sub-surfaces up to repaint by modifying the repaint list code
Struct weston_subsurface is dynamically allocated. For sub-surfaces, it
is completely populated.
For parent surfaces, weston_subsurface acts only as a link for stacking
order purposes. The wl_resource is unused, parent_destroy_listener is
not registered, the transform is not linked, etc.
Sub-surfaces are not added directly into layers for display or input.
Instead, they are hooked up via the sub-surface list present in parent
weston_surface. This way sub-surfaces are inherently linked to the
parent surface, and cannot be displayed unless the parent is mapped,
too. This also eases restacking, as only the parent will be in a layer
list. Also, only the main surface should be subject to shell actions.
The surface list rebuilding in weston_output_repaint() is modified to
process sub-surface lists, if they are non-empty. The sub-surface list
always contains the parent, too, unless empty. The collection of
frame_callback_list is moved to a later loop, to streamline the surface
list rebuild functions.
Features still lacking are:
- full-surface alpha support for compound windows
Changes in v2:
- fix a bug in surface mapping: commit a sub-surface would cause the
main surface to never be mapped.
- remove debug printfs
- detect attempt of making a surface its own parent
- always zero-alloc weston_subsurface
- apply wl_subsurface.set_position in commit, not immediately
- add weston_surface_to_subsurface()
- implement sub-surface commit modes parent-cached and independent
- implement wl_subcompositor.destroy and wl_subsurface.destroy
Changes in v3:
- rebased, and use the new transform inheritance code
- squashed the commit "add sub-surfaces to repaint list"
- fixed a buffer reference leak in commit_from_cache()
- Rewrite the sub-surface destructor code, and make it leave the
wl_subsurface protocol object inert, if one destroys the corresponding
wl_surface.
- replaced set_commit_mode with set_sync and set_desync
- allowed sub-surface nesting, and fixed repaint accordingly
- implemented nested sub-surface commit modes
- Made the sub-surface order changes from wl_subsurface.place_above and
.place_below to be applied when the parent surface state is applied,
instead of immediately. This conforms with the protocol specification
now.

Split the geometry information from weston_surface out into weston_view
The weston_surface structure is split into two structures:
* The weston_surface structure storres everything required for a
client-side or server-side surface. This includes buffers; callbacks;
backend private data; input, damage, and opaque regions; and a few other
bookkeeping bits.
* The weston_view structure represents an entity in the scenegraph and
storres all of the geometry information. This includes clip region,
alpha, position, and the transformation list as well as all of the
temporary information derived from the geometry state. Because a view,
and not a surface, is a scenegraph element, the view is what is placed
in layers and planes.
There are a few things worth noting about the surface/view split:
1. This is *not* a modification to the protocol. It is, instead, a
modification to Weston's internal scenegraph to allow a single surface
to exist in multiple places at a time. Clients are completely unaware
of how many views to a particular surface exist.
2. A view is considered a direct child of a surface and is destroyed when
the surface is destroyed. Because of this, the view.surface pointer is
always valid and non-null.
3. The compositor's surface_list is replaced with a view_list. Due to
subsurfaces, building the view list is a little more complicated than
it used to be and involves building a tree of views on the fly whenever
subsurfaces are used. However, this means that backends can remain
completely subsurface-agnostic.
4. Surfaces and views both keep track of which outputs they are on.
5. The weston_surface structure now has width and height fields. These
are populated when a new buffer is attached before surface.configure
is called. This is because there are many surface-based operations
that really require the width and height and digging through the views
didn't work well.

is a useful, self-contained project in it's own right, and we want to
move away from the "demos" label.
2) Another problem is that the wayland-demos compositor is often
called "the wayland compsitor", but it's really just one possible
compositor. Existing X11 compositors are expected to add Wayland
support and then gradually phase out/modularize the X11 support, for
example. Conversely, it's hard to talk about the wayland-demos
compositor specifically as opposed to, eg, the wayland protocol or a
wayland compositor in general.
We are also renaming the repo to weston, and the compositor
subdirectory to src/, to emphasize that the main "output" is the
compositor.
