Similar to 7c4f6cc145, if we don't have
a background image from the desktop-shell client or the touch point
for some other reason doesn't hit a surface we trigger a
segfault as we try to deref the seat->touch->focus NULL pointer.
For touch, another problem could be fudgey calibration that ends up
giving touch coordinates outside the output space.

Set up X windows that are transient for another window as transient
surfaces in shell.c. This keeps the transient windows on top of their

If a surface is not on any output, scheduling a repaint for it is a no-op.
weston_view_schedule_repaint() schedules repaints for all outputs that
overlap with the surface extents, but if the surface is completely
outside all outputs nothing will be scheduled. Fix this for now by starting
the slide slightly into the output.
The input-panel codes tries to see determine if a buffer has not yet
been attached (or a NULL buffer has been attached), and doesn't map
the input panel surface yet in that case. However, it test for
buffer_ref being NULL, which can happen for other reasons. The right
test is to see if surface->width is 0, which means that either a
buffer hasn't yet been attached or a NULL buffer has been attached.

If we're not currently showing the input panels, we still need to set the
panel position so that it's set when we later need to show them. This fixes
the initial flicker of the input panel in the wrong position when we first
show it.
If we don't have a background image from the desktop-shell client or the
pointer for some other reason doesn't have a focus we trigger a
segfault as we try to deref the seat->pointer->focus NULL pointer.

This is still fairly unstable, causes lockups with fullscreen and exposay,
leaves small preview surfaces on-screen if used on the same modifier as
mod-tab. We also only need on mod-tab implementation so lets see if we
can consolidate the current and this alt-tab implementation in 1.5.

All the libexec programs are only built when BUILD_CLIENTS is true,
so we can just assign libexec_PROGRAMS under the condition. This lets us
drop most of the variable assignments and simplify it a bit.

Previously the option was --enable-demo-clients and the conditional was
ENABLE_DEMO_CLIENTS. They control whether or not we install the demo clients
(ie all other clients than weston-terminal and weston-info). Rename the
option and the conditional to better reflect this.
Popup windows are relative to a plain wl_surface, so that custom surfaces
can have popups. This used for the desktop-shell panel for example. Also,
popups should be immediately on top of their parent surface, as they
typically represent an extension of an UI element in the parent surface
such as a combo box or menu.
This reverts commit da704d97fa.

If we don't mark the state as changed, we don't copy over next_state to
state and we fail to treat the surface as a transient. In particular,
we give it a random intial position instead of mapping it at the given
parent relative position.

Set the internal pointer for the client to NULL. This fixes a
segmentation fault at shutdown, where the shell would hang up before
and cause libwayland to call wl_client_destroy(). When the shell was
destroyed later, another call to wl_client_destroy() would cause the
crash.

Currently we destroy the renderer before the outputs are destroyed, but
that sometimes leads to an error since a reference to the renderer is
necessary in order to destroy a gl_renderer_output.
Since destroying the renderer is common among all backends, just move
that call into weston_compositor_shutdown() immediately after the
outputs being destroyed.
While the pixman image might be attached, the underlying buffer might be
already gone under certain circumstances. This is easily reproduced by
attempting to resize gnome-terminal on a fbdev backend.

Remove those listeners when the output is destroyed, otherwise they'll
point to invalid data that may lead to corruption when assigning a new
output for the view.

Record from the output of the surface that has keyboard focus for the
seat used to activate the recorder key binding. If there is no focused
surface, record from the first one.
Also, use the weston_transformed_region() to transform the damage
region of the output into the coordinates expected by read_pixels().
https://bugs.freedesktop.org/show_bug.cgi?id=71401
If the compositor hasn't been rendering for a while when the recording
stops, the time difference between the last rendered frame and that
moment won't be in the encoded video. Fix that by forcing one extra
frame to be recorded when the user presses the recorder key binding.

This client tests the wl_scaler and wl_surface_scaler protocol
extensions by cropping and then scaling a surface to ensure it is
rendered correctly. More details in comments in the code.
The pixman renderer doesn't use the weston_surface_to_buffer*
functions to alter coordinates depending on buffer transformation,
buffer scaling, and surface scaler (wl_surface_scaler).
pixman_transform_scale() is used instead to perform said
transformations without having to modify each coordinate.
Implements wl_surface_scaler.set by setting desired
src_{x,y,width,height} and dst_{width,height} values in the
weston_buffer_viewport struct, then altering coordinates in
weston_surface_to_buffer* functions if there is a scaler set for said
surface.
This registers the wl_scaler global object and lets clients create
wl_surface_scaler objects for surfaces. wl_surface_scaler.set is not
implemented so this doesn't really do anything useful yet.
Add cropping and scaling to wl_surface.
Add a global factory interface wl_scaler, which creates
wl_scaler_surface objects tied to a given wl_surface. The
wl_scaler_surface object can be used to set a cropping and scaling
transformation to change how a wl_buffer maps to wl_surface contents.
Changes in v2:
Take into account buffer_transform and buffer_scale, and try to explain
more clearly how the coordinate transformations work and what their
order is. Add, that crop and scale state is double-buffered. Explain
missing dst_x, dst_y. Clarify that undefined content still is some
content, but NULL buffer implies no content nor size.
Changes in v3:
Disallow zero values for dst_width and dst_height.
Open issues:
Should this be a separate interface like here, or just a wl_surface
request?
If we keep this as a separate interface, rename wl_surface_scaler to
wl_viewport.
Surfaces that are created by clients get their size automatically updated
by the attach/commit. Surfaces created directly by shells (such as black
surfaces) sometimes need to be manually resized. This function allows you
to do that while being somewhat less messy than messing with the internals
of weston_surface manually.

If the saved position for a fullscreen or maximized output view is in an
output that has been unplugged, the coordinates don't make sense
anymore. In that case, invalidate them and use the initial position
algorithm when changing them back to the basic state.

Previously, if a pointer was inside an output that was unplugged, it
could potentialy end up outside any valid output forever. With this
patch, the pointer is moved to the "closest" output to the pointer.
Set a flag when an output is being destroyed and use that to avoid
repainting. This allows functions that schedule an output repaint to
be called when the output is being destroyed without causing the
compositor to crash.
Use the output destroy signal to move the views in the event the output
was unplugged.

Previously, when an output was moved due to another output being
unplugged, the views on the first output would remain in the same

This patch adds an output_move signal that the views listen too in
order to repostion themselves in the event of an unplug.
