Widgets should be rendering to a cairo_surface for a particular
wl_surface, just like buffers are per surface.
window_flush() has a change in behaviour: it will now send
wl_shell_surface.set_toplevel also without a cairo_surface to be
attached. This shouldn't change anything in practice.

So that given a widget, we can access the surface specific data, like
buffers, and input and opaque regions.

They are per wl_surface state.
The frame widget is always on the main surface, since it can be created
only for the window. That is why frame_resize_handler() can simply
assume that the surface is the main_surface.

Repaint and resizing widget recursions must start from the root widget
of each (sub-)surface, so that buffers and regions get initialized
correctly. Make it easier by moving the widget field from struct window
to struct surface.

These are surface specifics, since buffers are surface specific.
SURFACE_HINT_RESIZE is moved together to the other SURFACE_* flags, so
that surface_create_surface() would not need two flags arguments.
struct toysurface::prepare vfunc checks for SURFACE_HINT_RESIZE, and
egl_window_surface_create() and shm_surface_create() check for the
non-HINT flags.

Fields 'allocation' and 'server_allocation' are surface specific. Fields
'saved_allocation', 'min_allocation', and 'pending_allocation' are
window specific, and will not be moved.
Field 'toysurface' is naturally surface specific, since it provides the
backing storage for the wl_surface.

Struct window has many fields that are directly related to the
wl_surface, more than to the window as a whole. When we start composing
a window from several wl_surfaces, these fields need to be per
wl_surface, not per window.
Start separating such fields from struct window into struct surface by
moving the wl_surface.

Handle the case when we the compositor somehow migrates from requiring
double buffering into working on single buffering, so we release the
extra shm buffer.
Currently, I do not think this can happen in practice, but in the future
it may happen with sub-surfaces.

Check for errors in the first wl_display_dispatch() call. Otherwise
doing something silly like
$ WAYLAND_SOCKET=999 ./clickdot
will segfault.

Make them explicitly mention EGL, otherwise one can easily think that
"failed to initialize display" refers to Wayland display.
Also explicitly mention falling back to wl_shm. I tested this with a
LD_PRELOAD trick that overrides eglBindAPI and makes it fail.

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.
weston-screenshooter is a helper binary that weston launches to write the
screenshot to disk. If somebody tries to launch it by hand, print a
warning and mention the screenshot keybinding.
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.
Tests especially, that attach-attach-commit does not result in a release
of the first buffer.
Also tests, that the old buffer is released when a new buffer has been
attached, committed, and displayed (frame callback).

To avoid duplicating the code for setting and waiting for a frame
callback, add helpers for it.
Convert move_client() to use the new helpers.

By default enabled but one can disable it by passing --disable-xwayland-test
to the configure script. Also, the weston-tests-env script is trying to load
xwayland.so in either case, but it behaves resilient in the absence of that
meaning all the other tests are still going to be kicked for running.

When cairo-gl and mesa-glu are present on the system, autoconf successfully
recognizes both. However, I was wondering why weston-screensaver was not
building since autoconf reported all dependencies were met.
Move the mesa-glu PKG_CHECK before the conditional. Additionally, remove
redundant check for enable_egl, as it is implied when GLU is 'yes.'

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.
This way libtool will remember the libtoytoolkit LIBADD libraries.
We can drop the toolkit_libs hack and just link to libtoytoolkit.la and
libtool will add the dependencies.
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.
All the clients here were missing the global_remove handler. Because
window.c did not have it, weston-desktop-shell and weston-keyboard
segfaulted on compositor exit, as they received some
wl_registry.global_remove events.
Add more or less stub global_remove handlers, so that clients do not
crash on such events. Toytoolkit and all applications would need a lot
more code to properly handle the global object removal.

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.

We handle FAIL_TEST tests by simply inverting the success flag. The
problem with this is, that if a FAIL_TEST fails by a SIGSEGV, it will be
interpreted as passed. However, no code should ever cause a SEGV, or any
other signal than ABRT. And even ABRT only in the case of an assert()
that is meant to fail. We would probably need more sophistication for the
FAIL_TEST cases.
For now, just interpret any other signal than ABRT as a hard failure,
regardless whether it is a TEST or FAIL_TEST. At least segfaults do not
cause false passes anymore.
