When a surface in deemed unresponsive and we trigger the busy cursor, it's
no longer possible to rotate the surface. This is clearly unacceptable.
This patch adds handling of right clicks to the busy grab so that we can
continue to rotate a surface even if the client is sleeping.

If our surface has width and height set to the same dimensions as the output
then we can bypassing the scale factor calculation and addition of the
transformation.
The use case that led to this optimisation is the playback of video using
gstreamer-vaapi with the "scale" method. The video is the same dimensions as
the output (1080p.)
When fading in, if a repaint was triggered after a call to
weston_compositor_fade() but before the first call to fade_frame(),
the fade surface wouldn't be drawn because its alpha channel wasn't
initialized properly.
We can now handle fullscreen X windows. X clients request to go fullscreen
buy sending a _NET_WM_STATE client message to the root window. When that
happens we call into the shell interface and asks the shell to make the
surface fullscreen. The shell will then resize the window, which causes
the X wm to configure the X window appropriately.
Make sure we ignore configure requests from fullscreened clients and send out
the synthetic configure notify as required in that case.
Finally, inspect _NET_WM_STATE before mapping so we can handle initial
fullscreen correctly.
Add a frame buffer backend using pixman to render to fbdev.
This has been tested against nouveaufb but nothing else. Much of the code
came straight from the rpi backend (and copyright has been attributed
accordingly).
The behaviour of this backend on less modern frame buffers has yet to be
tested.
The refresh rate is calculated from the frame buffer's metadata. Every frame
is finished in synchrony with the refresh rate.
Frame buffer devices are currently specified on the command line (or using
the default of /dev/fb0); udev could be used in future to enumerate them.
pixman is used for compositing, and a suitable pixman format is built from
the frame buffer's metadata. This doesn't support the full range of
frame buffer formats, but does support varying BPPs of RGBA and ARGB. That
should be enough for now.
The following are not currently supported:
• FOURCC
• Non-packed formats (interleaved, planes, etc.)
• Non-true-colour formats (monochrome, greyscale, etc.)
• Big-endian formats (with component MSBs on the right)
• Non-RGBA and non-ARGB formats

The drm planes (sprites) only support translation and scaling. Now that
we have matrix.type, we can just look there to see if the transform is
compatible with kms.
Introduce several matrix transform types and track type for matrix.
Could be usefull for activating some fastpath that depends on some
transform type.

Before, cairo-util.h would combine pixman and cairo includes. X11 and
Wayland compositors uses this to load an image as a pixman_image_t but are
forced to include cairo headers. Clients use load_cairo_surface to
load images as cairo_surface_t's, but are forced to include pixman.h.
We move the load_image pixman prototype to its own header, so compositors
can get at the pixman prototype without including cairo.h and clients
can include the cairo based function without including pixman.h.
The X11 backend uses a shadow buffer to be able to support transformed
outputs. However, this belongs in the renderer, since otherwise this
code would have to be copied into every backend that uses the pixman
renderer and supports transformed outputs.
The Android backend has been fairly unused, since we do not have
projects actively using it. It gets basic build testing as part of the
normal build, but runtime testing it takes a considerable effort, and so
I have not done that in a long time. The code is slowly rotting, and
with new emerging backends it starts to be a burden, since it cannot use
udev, but needs evdev.
Therefore to ease Weston going forward, remove the Android backend. If
someone misses it, it can still be found in the stable 1.0 branch, and
of course resurrected from git history if someone wants to put in the
effort and maintain it.

The list became stale probably when the lock_layer was introduced. Now
one less (ab)user of weston_surface::link.
Also add a comment on screensaver_configure(), that it is (and has been)
broken for pre-started screensavers.

To be able to have a fullscreen surface on one output, and interact with
surfaces on another output, don't lower the fullscreen layer on
activate.

The input region of the black surface placed under the fullscreen shell
surface did not have a specified input region. Because the initial input
region of a surface is infinity, no other surface on any other output
could get any focus.

In particular if the hash table lookup fails and returns NULL then that value
would be passed into weston_wm_window_schedule_repaint which does not accept a
NULL value.
weston_compositor::read_format is in Pixman values now, so comparing to
a GL value does not work. Compare to the right value.
This fix affects only the log output of the GL renderer.

Call drm_output_init_egl() instead of duplicating the gbm surface and
gl renderer state initialization code.
Note that this makes error handling a bit worse. Before, if we failed
to allocate a gbm surface we could still recover. Failing the renderer
state creation would lead to inconsisten state. Now we end up in
inconsistent state on both cases.
At this point, we reallocated the gbm surface, but we don't have an
fb with the right size to use. If we're going to a larger mode, the fb
would be too small and the mode set would fail. Besides, the repaint
logic will already do a mode set if necessary, so rely on that instead.
When an output suffers a mode switch, it is possible that a pointer
was inside the old output area but falls outside of it with the new
size. In that case, move the cursor to the output's bottom-right
corner. Otherwise, there's a crash in clip_pointer_motion().
After a mode switch, the output region and transformation matrix need
to be updated. The call to weston_output_move() would do the former but
not the latter, but calling that when the output remains in the same
coordinate doesn't make much sense. Instead, update this state and the
transformation matrix in weston_output_mode_switch().
We want to make sure that the matrix symbols are exported from weston and
that modules get them from there. To do that, we pull matrix.[ch] out of
libshared and back into weston. calibrator now also links to matrix.[ch]
and we add a IN_WESTON define to enable the WL_EXPORT macro when compiled
inside weston.
Trying to create a ARGB framebuffer for scanout results in EINVAL when
trying to queue the pageflip. This patch overrides the format we pass
to addfb2 in case of primary buffers like we do for sprites.
Since we always have to inspect and override the format, don't try to
look up the format in drm_fb_get_from_bo(). Instead return format from
drm_output_check_scanout_format().
Rename drm_surface_format_supported() to drm_output_check_sprite_format()
and make it follow the same convention.
We started scanning out ARGB surfaces in commit e920941032.
Since the call to drmModeSetPlane() fails with EINVAL if the supplied
fb has an unsupported format (which is the case of ARGB8888), the fb
format needs to be overridden.
