The config.h.in generated by autotools has much more entries than before,
so update the pre-configured config.h.win32.in.

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

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.
