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.

Add presentation clock setters that verify the given clock actually
works. Offer an automatic choice of a software fallback clock, when a
backend has to always use clock_gettime() to approximate the
presentation time.
The DRM backend already queried the DRM about the clock id, just let the
DRM backend set the presentation clock from that.
For all other backends which do not get a timestamp from the driver,
call the software clock setter to choose a suitable clock.
Report the chosen clock via presentation.clock_id event to clients.
In finish_frame(), upgrade the argument from uint32_t milliseconds to
struct timespec which can accurately hold the presentation clock values.
This will be needed when weston_output_finish_frame() starts to send out
presentation_feedback.presented events.
While at it, replace gettimeofday() calls with clock_gettime() using the
chosen presentation clock, so we manufacture presentation timestamps
from the presentation clock when the gfx drivers cannot give us a proper

When SIGCHLD fires, we may have more than one zombie to be collected.
Run waitpid() in a loop until no more zombies are found, and clean them
all up.
It looks like the SIGCHLD signalfd does not trigger again for remaining
zombies, so we need the loop.
This works around a crash in text_backend_notified_destroy, which ends
up using stale input_method.client if the sigchld handler is not called.
The crash could be triggered by removing both weston-desktop-shell and
weston-keyboard, so that both would try to respawn and give up, and then
quitting Weston.

weston_client_start() is a new wrapper around weston_client_launch(),
that does the process tracking on its own, and logs the process exit
status.
When users of weston_client_start() want to know when the process exits,
they should hook into the wl_client destroy signal. This works for cases
where the client is not expected to disconnect without exiting.
As wl_client destructor and the sigchld handler run in arbitary order,
it is usually difficult for users to maintain both struct weston_process
and a struct wl_client pointer. You would need to wait for both
destructor and handler to have run, before attempting to respawn the
client.
This new function relieves the caller from the burden of maintaining the
struct weston_process, assuming the caller is only interested in client
disconnects.

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 95ec0f95aa accidentally also
prevents this bug from happening, because it adds a test against the
transform.masked_boundingbox in weston_compositor_pick_view().

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.

this adds a mechanism to mask the views belonging to a layer
to an arbitrary rect, in the global space. The parts that don't fit
in that rect will be clipped away.
Supported by the gl and pixman renderer only for now.
This introduces a new struct, weston_layer_entry, which is now used
in place of wl_list to keep the link for the layer list in weston_view
and the head of the list in weston_layer.
weston_layer_entry also has a weston_layer*, which points to the layer
the view is in or, in the case the entry it's the head of the list, to
the layer itself.
This new structure is used for both weston_surface.pending and

The zoom translation is just a scale and a translate. The translation
is calculated based on the coordinates of the pointer which are in
global space. Previously the calculated translation was transformed by
the output transformation so that when the zoom transform is applied
after the output transform then it will be correct. However if we just
apply the zoom transformation first then we get the same result
without the zoom code having to be aware of the output transformation.
This also fixes weston_output_transform_coordinate which was applying
the output and zoom transforms in the wrong order.
https://bugs.freedesktop.org/show_bug.cgi?id=78211
When converting output-relative coordinates (such as from an input
event) to global coordinates it now takes into account the zoom
transform. Previously this would only work for the primary pointer
because the transform doesn't affect the primary pointer position due
to that way zoom follows the mouse. Touch events and multiple pointers
were not working correctly.
https://bugs.freedesktop.org/show_bug.cgi?id=68620
In order to apply the zoom transformation to the output matrix, Weston was
doing the following:
• Create a temporary matrix to hold the translation
• Invert the translation matrix using weston_matrix_invert into
another temporary matrix
• Scale that matrix by the scale factor
• Multiply the current matrix with the temporary matrix
Using weston_matrix_invert to invert a translation matrix is over the top.
Instead we can just negate the values we pass to weston_matrix_translate.
Matrix multiplication is associative so creating a temporary matrix to hold the
scale and translation transform should be equivalent to just applying them
directly to the output matrix.
Previously, because of the wrong width/height,
weston_surface_to_buffer_* would return the wrong values when
wl_viewport was used in combination with wl_surface.set_buffer_transform.

Let's make the source and destination size rules consistent: neither can
have zero, {-1, -1} disables it, and other negatives are not allowed.
The sanity of allowing zero sized source rectangle as debatable. Now the
minimum becomes 1/256x1/256, and with output_scale the actual samples
may be even smaller. That should be enough.
On not allowed values, raise a protocol error. This should help catch
bugs in clients that accidentally send garbage values.
The old wl_viewport.set request remains the same, and can still produce
zero sized source rectangle.

This patch adds an option to the RDP compositor to disable
desktop resizes initiated by RDP peer. The current behaviour
is that if an incoming RDP peer suggests a resolution that is
not the current one, a mode_switch() is done and the desktop is
resized to that new resolution. This new flag allows to disable
that behaviour. If the flag is set, the new behaviour is that the
RDP peer will be instructed to resize to the size of the desktop.
