Adding a layer difference may mean the pipeline overrides all of the
layers of its parent which might make the parent redundant so we
should try to prune the hierarchy.
This is particularly important for CoglGst because whenever a new
frame is ready it tries to make a copy of the pipeline it last used
and then replace all of the textures in the layers. Without this patch
the new pipeline would keep the parent pipeline alive which means also
keeping the old textures alive so all of the frames of the video would
effectively be leaked.

The current recommendation for pipelines is that once they have been
used for painting then they should be considered immutable. If you
want to modify a pipeline you should instead make a copy and unref the
original pipeline. Internally we try to check whether the modified
copy replaces all of the properties of the parent and prune a
redundant ancestor hierarchy. Pruning the hierarchy is particularly
important if the pipelines contain textures because otherwise the
textures may be leaked when the parent pipeline keeps a reference to
it.
This test verifies that usage pattern by creating a chain of pipeline
copies each with their own replacement texture. Some user data is then
set on the textures with a callback so that we can verify that once
the original pipelines are destroyed then the textures are also
destroyed.
The test is currently failing because Cogl doesn't correctly prune
ancestory for layer state authority.

In 97a4cc8c, we accidentally lost the check that kept us from
sending multiple configures to a window before it responds to
_NET_WM_SYNC_REQUEST. So _NET_WM_SYNC_REQUEST stopped working
properly. Add a check back with the same effect.

During a resize, if we don't have a configure pending, then a counter
change shouldn't trigger anything other than the normal drawing:
it's just a spontaneous frame from the application. So don't try
to update the position or remove our timeout ID.

ClutterBinLayout's get_preferred_width / get_preferred_height
doesn't respect fixed child positioning when calculating the
size of the layout, but does when allocating. This is absurdly
broken, but it's what we're given. Use a ClutterFixedLayout,
which doesn't have these issues.

Trying to track the fullscreen status outside of Mutter, as GNOME Shell
was doing previously, was very prone to errors, because Mutter has a
very tricky definition of when a window is set to be fullscreen and
*actually* acting like a fullscreen window.
* Add meta_screen_get_monitor_in_fullscreen() and an
::in-fullscreen-changed signal. This allows an application to
track when there are fullscreen windows on a monitor.
* Do the computation of fullscreen status in a "later" function that
runs after showing, so we properly take focus into account.
* To get ordering of different phases right, add more values
to MetaLaterType.
* Add auto-minimization, similar to what was added to GNOME Shell
earlier in this cycle - if a window is set to be fullscreen, but
not actually fullscreen, minimize.

Since the tile mode is now always reset on maximize(), this code
no longer does anything (not to mention that side-by-side tiled
windows haven't snapped back for a while now).
https://bugzilla.gnome.org/show_bug.cgi?id=682779
We used to restore side-by-side tiling when unmaximizing, so we
kept the tile-mode during maximization. Since commit 10d53fc7d
there's no longer a good reason to do so, and it can result in
tile previews being shown erroneously on window drag operations
without motion (double-click on titlebar), so reset the tile
mode in maximize().
https://bugzilla.gnome.org/show_bug.cgi?id=682779
The tile preview is expected to be shown underneath the focus window.
However the code that restacks the preview broke when override-redirect
windows were moved to a separate window group.
To fix, special-case tile previews to put them in the NORMAL layer.

If _NET_WM_OPAQUE_REGION is set when the window is first mapped, the
initial load_properties will happen before the window actor is created,
and we'll have a call to meta_compositor_window_shape_changed. Just
fizzle this call out instead of doing anything fancy, as we'll pick
up the opaque region when the window actor is eventually created.

If clutter is built with both X11 and Wayland support, prefer the
(more complete for now) X11 backend. This matches GTK+'s current
ordering.
This allows distributions to ship a clutter version with both backends
built, and using an envvar to switch to the wayland backend and test
applications.
In the future, applications would be able to choose which backend
they prefer and in which order.

Previously, we were handling failure to respond to _NET_WM_SYNC_REQUEST
in the code path for throttling motion events. But this meant that
if a window didn't respond to _NET_WM_SYNC_REQUEST and there were no
motion events - for a keyboard resize, or after the end of the grab
operation - it would end up in a stuck state.
Use a separate per-window timeout to reliably catch the failure to respond
to _NET_WM_SYNC_REQUEST.

During resizing we froze window updates when configuring the
window, and unfroze the window updates when processing the
next resize. This wasn't absolutely reliable, because we might
not have a next resize. Instead tie window freezing more
directly to the current sync request value - a window is
frozen until it catches up with the last value we sent it
in _NET_WM_SYNC_REQUEST.
Testing with unresponsive clients showed that there was a bug
where window->disable_sync once set, would not actually disable
sync, but it *would* disable noticing that the client was
unresponsive for the next resize. Fix that by checking for
->disable_sync before sending _NET_WM_SYNC_REQUEST.
