Because clones may not have identical geometry to their source actors.
So we can't use the geometry of the source actor to decide to take the
more optimized (more clipped) path.

The "paint" signal of ClutterActor has been a pain for everyone involved
long enough now, turns out we actually use it nowhere except tests
anymore (which has been handled in the last commits), so get rid of it
for good before anyone starts using it again.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1522
The "paint" signal of ClutterActor is deprecated and will be removed. We
have a good replacement to get notified about stage paints nowadays,
that is "after-paint" on ClutterStage, so switch to that signal where it
makes sense.
I didn't bother to update the few tests (namely Clutters
conform/texture-fbo.c, conform/text-cache.c,
interactive/test-cogl-multitexture.c and Cogls
conform/test-multitexture.c, conform/test-texture-mipmaps.c) where it's
harder to replace the signal since we don't build those anyway.

The paint-wrapper test wraps around the painting process of an actor to
paint its own texture before and after painting, it does that using the
"paint" signal.
This signal is deprecated and will be removed from Clutter, and since
this "use-case" won't be supported anymore afterwards (the proper way is
to use a ClutterEffect for things like this), remove the test.

Rely on the seat stage, or other ways to fetch it. Also rely that
there is actually a single stage, so that we assign the right stage
to all events going out of the seat, in a single place.

This is a bit scattered around, with the setter/getter in Clutter, and
it only being only directly honored in Wayland (it goes straight through
device properties in X11).
Make this private native API, and out of public ClutterInputDevice API.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1486
Make the upper part agnostic about the device being relative in order
to avoid applying keep-aspect. The X11 bits already are, so make it
sure it's also the case for the native backend.

The semantics for libinput events are not as expected here. Besides
it's pointless, as those should arrive per-slot in a burst, and we
cancel on the first event.
We can simply use the Clutter event for this.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1486
As it does seem from a read to libinput code, TOUCH_CANCEL events
actually do contain slot information, and are emitted per-slot.
This means we can avoid iterating over the slots ourselves, they
are still expected to be sent altogether.

We want to coalesce multiple touch events into the same wl_touch.frame
event. Instead of poking internals to peek the touch events (and their
slots) coming at us before we handle them, simplify things by queueing
the event at a slightly lower priority than events, so we are ensured
to handle all pending input events before sending the event.
If there's no pending events, we can just send the frame event. As it
doesn't make sense to hold any longer.

When malformed modes are provided and no valid mode spec is found, mutter
will eventually try to access the last element of an empty list. Warn about
this and exit properly.

We will use a dedicated variable when transitioning to/from fullscreen state
and leave the previously used 'saved_rect' exclusively for transitioning
between floating and maximized state.

Implements the "prior window window geometry dimensions" as described in
the documentation of 'xdg_toplevel' request 'unset_maximized':
"If available and applicable, the compositor will include the window
geometry dimensions the window had prior to being maximized in the
configure event."
and 'unset_fullscreen':
"The compositor may include the previous window geometry dimensions in
the configure event, if applicable."
Fixes https://gitlab.gnome.org/GNOME/mutter/issues/792.
If this call is available, we can turn libX11 IO errors (fatal by definition)
into something we can recover from. Try to dispose all X11 resources and close
the display instead, so the compositor can survive the event.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1447
If the MetaX11Display abruptly closed when X11 windows were present,
we would still try to deal with them while freezing/thawing for the
"fade out" animation.
At the bottom of that, the X server may be gone, just try to cope
with it.

Since commit eb9cd3857d we initialize the allocation of ClutterActors to
an UNINITIALIZED ClutterActorBox. We do that to ensure the actor even
emits notify::allocation in case it got a new valid allocation of
0,0,0,0.
Now there's still the case where an actor gets removed from the
scenegraph and added again to a different parent, in this case we still
don't emit notify::allocation right now in case the new allocation
equals the old one. There's two good reasons to do so though:
1) To Clutter, there's no difference between a newly created actor and
an actor which got removed from the scenegraph, it's not consistent to
always notify the allocation property in the former situation, but not
always notify it in the latter situation.
2) When an allocation changes, Clutter notifies the subtree of that
actor about an absolute geometry change (see the call to
transform_changed() in clutter_actor_set_allocation_internal()). Now
when an actor gets reparented, obviously the absolute geometry might
change, so to make sure transform_changed() is always called in that
case we need to make sure an allocation change happens.
So simply reset the allocation property of the actor to an UNINITIALIZED
ClutterActorBox as soon as it gets unrealized.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1498
We introduced the absolute_origin_changed flag when preparing for the
removal of ClutterAllocationFlags in commit dc8e5c7f8b. Turns out in the
mean-time commit df4eeff6f2 happened, which renders the whole
absolute_origin_changed flag moot.
That's because we now notify the whole subtree about the absolute origin
change by calling transform_changed() when the allocation of an actor
changes. transform_changed() traverses the subtree and calls
absolute_geometry_changed() on every actor immediately, which renders
the whole propagation of the absolute_origin_changed flag obsolete.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1498
Since we now moved the queuing of relayouts into the mapping and
unmapping functions, we no longer need to do it when adding or removing
a child, that's because removing a child always unmaps the child, and
adding it to a stage (if it's visible) will map it.
So remove those calls to queue_relayout() since they're no longer
needed.
With the above we no longer queue a relayout in
clutter_actor_add_child_internal(), that means there's one place where
we need to explicitely queue relayouts now: That's when using the
set_child_at_index/above/below() APIs, those are special because they
avoid unmapping and mapping of actors and would now no longer get a
relayout.
