If we for some reason have an error trying to allocate the framebuffer,
we'll still mark the tower as revalidated. Move the validation to the
end of the actual revalidation code to solve this.
It's a deprecated API that can surprise us. Namely, when the internal
format passed is COGL_PIXEL_FORMAT_ANY, it will *always* allocate an
RGBA8888 pixel format texture, even if we only passed it a RGB format
or even an A8 format.
cogl_texture_2d_new_with_data is the newer, better API and doesn't have
these warts.
These methods allow us to set and get xkbcommon keymaps as well as
locking a specific layout in a layout group.
With this, we introduce dependencies on xkeyboard-config, xkbfile,
xkbcommon-x11 and a libX11 new enough to have xcb support.

At this point there shouldn't be any system capable of running mutter
that doesn't have it and we're introducing functionality like setting
the keymap that has an hard requirement on it.

Since commit a7b7213017, we rely on the standard property
system to initialize the window type (and likewise for the window
role since commit 031154a400). However as property hooks are
never run for properties that are not set, we end up not initializing
the window type correctly for windows with no _NET_WM_WINDOW_TYPE
property (which includes virtually all OR windows, causing them to
show up in pagers and the Shell overview and resulting in frequent
crashes due to breaking reasonable assumptions all over the place).
Introduce a new FORCE_INIT flag to allow forcing hooks to run
even when the corresponding property is unset, and use it for
both _NET_WM_WINDOW_TYPE and _NET_WM_WINDOW_ROLE.
This way the xserver never paints the frame background, even if
the client window is destroyed. This allows us to have clean
destroy window animation.
There is no problem with interactive resizing because applications
are using the XSync protocol, so we're not painting unless the
client has redrawn.

Connecting to size-changed is wrong -- size-changed tells us when
we *told* the X server or resize the window. For X11, we're sort of
guaranteed that the surface will be updated at some point before the
next frame, but for Xwayland, we can't be sure that the new surface is
attached at this point.
This fixes weird artifacts when resizing apps like xclock.
This was wrong for subsurfaces that extend beyond the parent's shape,
since the paint volume would be wrong in this case. Instead of using the
shape region which can be out of date and wrong, just use the union of
our children's volumes, which is a lot easier to manage.
Refuse to create a touch resource if we don't have the capability
(for misbehaving clients), and don't attempt to use touch data
structures that are not initialized.
This is a terrible hack. We need to figure out a better way to do
interactive resizes.
This fixes weird resizing from the left bugs when using GTK+, which is
really slow at acking configures.
This is an easy way to get into an infinite loop where we're constantly
re-sending stuff to the window. If it worked once, it probably won't
work again.
We assume in meta_window_wayland_move_resize that the next commit that
changes the geometry will always be for our next pending operation, so
if we have a move pending on a resize, the next commit will trigger the
move. This is, of course, fundamentally wrong.
We broke this assumption even more now that we don't fizzle out calls to
meta_window_move_resize_internal and now call it on every commit, which
means that a simple damage and then commit would complete a pending
move.
This was even broken by apps like weston-terminal, which, when clicking
on the maximize button, first redraws the terminal with the maximize
button state back on hover on press, and would only redraw when it got
the configure event with the coordinates.
To track the correct commit to apply the move for, we implement the
ack_configure request and ignore all move/resizes that happen before
that.
Right now, we actually fizzle out the entire move/resize if there's a
future pending configure we're waiting on.
Sometimes we can get a host event without having the display up and
running yet. Just don't pass it to the compositor in that case, since it
won't be possible for it to have any event that matters.
