When the pointer is constrained and the surface in which it is
constrained gets committed, we may warp the pointer in some
circumstances. In order to do that, we need the associated view
transforms up-to-date. So update view transforms when this surface gets
committed.
This fixes an issue in which we'd hit an assert when trying to warp the
pointer, as we were trying to transform views with dirty transforms.
This is a leftover of d611ab24fd

This should prevent extra focus signal emission the similarly to
how default_grab_pointer_focus() does, though we don't have the
surface jumping logic here.
This stops xdg pings from being sent every output repaint during
a grab when the pointer isn't in any windows belonging to the
grab parent.
An example would be running weston-terminal, bringing up the
right click pop-up, and moving the mouse onto the desktop while
another client causes repaints.

This prevents a spurious pointer focus clear at the start of a grab.
This would, for example, cause an extra pointer leave when bringing

When the new option is enabled, headless backend will draw decorations
around its outputs. This makes the actual "framebuffer" larger by the
thickness of the decorations to keep the video mode area free for
clients.
This will be needed for a future test, that will ensure that GL-renderer
will paint the output decorations correctly.
The output title is deliberately NULL, because text rendering is
unpredictable and depends on e.g. what fonts are installed in the
system. Therefore screenshot testing of any text would be really
painful, so let's avoid that.
The decorations setup code is mostly copied from wayland-backend.

This services output capture tasks for the 'framebuffer' and 'full
framebuffer' pixel sources.
Both pixel sources come from the same source: the EGLSurface. The only
difference is the area. The EGLSurface contains the borders used for
output decorations, hence 'full framebuffer' is possible to capture.
We use GL_ANGLE_pack_reverse_row_order extension to make glReadPixels
return the image data in the layout we need for wl_shm buffers directly.
Without the extension we have to flip manually.
Another extension to the same effect is MESA_pack_invert, but this is
not specified for GL ES. It also uses a different token value, so it
cannot be directly substituted even if supported.

This services output capture tasks for the 'framebuffer' and 'blending'
pixel sources.
Just like the old screenshooting path, the 'framebuffer' pixel source is
the hardware buffer, whether a shadow is used or not. This may not be
the best for performance, but you do get the real framebuffer contents.
Maybe it's rgb565, or even less.
When the shadow buffer is used, I realized it is effectively the same as
the intermediate blending buffer in GL-renderer when color management is
used. Pixman-renderer does non-linear blending only, so the shadow
buffer is in the blending space. The shadow buffer is also always 8 bpc
regardless of the hardware framebuffer, so the read-back may be
different from the hardware framebuffer. Read-back from the shadow is
optimal for performance, but not what the hardware gets.
'full-framebuffer' source cannot yet be implemented, because backends do
not tell Pixman-renderer about the margins where the wayland-backend
blits the output decorations. The target "hardware" buffer handed to
pixman-renderer does not allow accessing the decorations area.

This implements the basics of the new screenshooting protocol. The
actual pixel operations will be implemented separately in the renderers
and DRM-backend.
See the previous commit "protocol: new screenshooter protocol" for why.
If DRM-backend needs more from weston_capture_task when it implements
writeback screenshooting, it will be easy to add user_data or expose
weston_capture_task::link for the backend to use. Those were not added
yet because it is uncertain what is actually needed.
The DRM-backend no-damage optimization requires special handling here as
well. See also 7f1a113c89 .

If the view transform is dirty it might be incorrect. Also, we normally

There are two problems here, one is that the surface jump logic only makes
sense if the view remains the same.
The more important fix is that pointer coordinates are in global coordinates
and we want view coordinates, so this test was always wrong and led to an

This introduces a few getters to retrieve the pending state from
libweston-desktop, now just libweston, and makes use of it,
specifically get_pending_maximized to avoid sending invalid
dimensions to the client in the particular use case
set_maximized/unset_fullscreen.
These pending state getters are useful to query/poke a not-applied
yet state, and could be useful where we don't have a buffer attached
where the client might be set-up as maximized, but internally libweston
hasn't yet applied that pending state.

Before this patch, when a new head is found its information is printed
first as "updated" and then as "found" in the log.
The reason is that drm_head_create() calls drm_head_update_info() which
printed the head as "changed". Then drm_head_create() itself prints it
as "found".
This fixes it to print only once as "found".

Provide a log throttling implementation so we don't have to open code this

Instead of just logging a single time, allow some finer control. We allow
logging of a specified number of events. Additionally, we have an optional
timeout after which the event count is reset so we can log at most N
events in M ms.
The first new event printed after the timeout expires will also include a
count of suppressed events.
