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.

If an actor has not been painted yet, or it's not going to be painted,
we can ignore transitions queued on it.
By ignoring transitions on actors that have not been painted yet, we can
avoid doing work during the set up phase of the scene graph, as well as
avoiding actors "flying in" from nowhere.
Obviously, we have to take into account potential clones, so we need to
check that the actor is not part of a cloned branch of the scene graph,
as well as checking if the actor has mapped clones.
If an actor is unmapped then it won't be painted, so we can safely
short-circuit out of _clutter_actor_queue_redraw_full() if the mapped
flag is not set.
We need, on the other hand, make an exception for Clones, otherwise
they won't receive notification that the source actor has changed
and they won't be painted.
This allows us to ignore redraws queued on children of invisible
parents, and avoid traversing the scene graph.
Instead of using signal notifications, we should be able to keep track
of the clones of an actor from within ClutterActor itself, using private
API. There's no point in pretending that people can actually create a
Clone class out of tree, given the amount of invariants we have to punch
through in order to implement a proper replicator node of the scene
graph, so we can just skip the signal emissions and just do the right
thing at the right time.
More comments are warranted: these functions are pretty much full of
potential side effects, and I'd really like to avoid keeping everything
in my head forever.
Along with the comments and the type casting reduction, I sneaked in a
one line change that is clearly correct after reading the flow of the
whole thing: we queue only a relayout after three potential redraws have
been queued. If we manage to miss a redraw and yet still get a relayout
then it means that most of our assumptions are fundamentally wrong, and
that we ought to dump this whole business of computer programming, and
just go back to being a hunter-gatherer species.
Since XIQueryVersion, the bad API that it is, chooses the first client
version that it gets, we need to ensure that we pass XIQueryVersion the
new XI2.3 version, knowing fully well that Clutter won't be confused
by the new features.

The X server should fill in the minor version that it supports in the
case where it only supports the older version. We should not get a
BadRequest or fail the version check if we pass something higher.

Window actors might be temporarily parented to intermediate actors during
effect, but we should not require that the plugin keeps track of stacking.
Rather, assume that the intermediate groups holds a whole stack, and
applying position within it.

-Make entries of the property sheets more like the property sheets of the
projects in the GTK+/Clutter stack, mainly changing CoglApiVersion to
ApiVersion, for better consistency, and update the corresponding projects
-Add command item in property sheets to build introspection files for Cogl
and Cogl Pango.
-Stop building and installing the cogl-msaa example, as it is something
that isn't really meant for Windows, and causes an internal compiler error
on Visual Studio 2010 x64 builds
This reverts commit 83dbf79986981fac9ec0f2575b7c7cb32f629f0f.
On further consideration we realized that needing this change either
indicated a bug in the code using cogl, or that it was a symptom of
some other bug in Cogl resulting in us returning NULL in
cogl_buffer_map_range but not returning a CoglError too.

If a pipeline has been flushed that disables depth writing and then we
try to clear the framebuffer with cogl_framebuffer_clear4f, passing
COGL_BUFFER_BIT_DEPTH then we need to make sure that depth writing is
re-enabled before issuing the glClear call. We also need to make sure
that when the next primitive is flushed that we re-check what state the
depth mask should be in.

This makes sure that a viewport change when comparing between separate
framebuffers also implies a clip change when we are applying the Intel
gen6 workaround for broken viewport clipping. Without this then
switching between different size framebuffers could leave a scissor
matching the size of a previous framebuffer.

This makes some changes to _cogl_bitmap_gl_bind to be more paranoid
about bad access arguments and make sure we don't mark a bitmap as bound
if there was an error in _cogl_buffer_gl_bind.
We now validate the access argument upfront to check that one of _READ
or _WRITE access has been requested. In the case that cogl is built
without debug support then we will still detect a bad access argument
later and now explicitly return before marking the bitmap as bound, just
in case the g_assert_not_reach has been somehow disabled. Finally we
defer setting bitmap->bound = TRUE until after we have check for any
error with _cogl_bitmap_gl_bind.
