Just because of implementation details, this is only relevant to Wayland,
and is done via ::effects-completed handlers there. Ideally, Clutter should
notice by itself about effects starting, finishing, and affecting picking.
Doing this in generic code seems slightly cleaner in the interim.

In the wayland code we are in synchronization with the events that
the ClutterStage is managing at the moment. Asking the ClutterSeat for
the pointer position gets ahead of the current events, and may result
in imprecise coordinates sent in wl_pointer.enter.
To be in consistence with the motion events that might be already
queued, we should ask the stage for the last known coordinates.

To clear a pointer constraint, the Wayland backend passes a NULL
constraint to the native input backend.
The new async API however tries to reference/un-reference the given
object to use it while running in a separate task, which leads to a
warning from GLib trying to g_object_ref()/g_object_unref() a non
GObject pointer.
To avoid that issue, simply set the data only if the given constraints
pointer is not NULL.

find_focusable_ancestor() may pick an ancestor window which is not
mapped or hidden, and setting focus on that window will fail.
Be a tad more selective when looking for a focusable ancestor, to reduce
the chance of meta_window_focus() not focusing the happy chosen one.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1643>
The function focus_default_window() optionally takes a MetaWindow
argument denoting a window that should not be focused.
That function calls focus_ancestor_or_top_window() which in turn
calls meta_window_focus() to pass focus to another window.
However meta_window_focus() gives no guarantee that the given window
will end up being the one focused, and can fail in various and creative
ways.
If that fails, we could possibly end up with the focus window being the
one to avoid, while the caller assumes focus was changed, going as far
as asserting that fact like meta_window_unmanage() does.
As a result, mutter may abort simply because meta_window_focus() failed
to set focus on the expected window.
To avoid that issue, check that the focus did not end up on the window
that we explicitly did not want, and if that's the case, simply fallback
to the default focus window.

As planned and prepared with the last commits, let ClutterStage take
care of tracking input devices and their respective actors. This means
we now can remove the old infrastructure for this from
ClutterInputDevice.

Power saving changes in laptop panels enable/disable the attached
touchscreen input device, this is an asynchronous operation that
may be happening while the device is disappearing.
In fact, closing the lid is such perfect storm where both things
happen around the same time.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1644>
Currently, the MetaInputDeviceNative owns the libinput_device, with the
small catch that it is eventually finished in the main thread (as the
CLUTTER_DEVICE_REMOVED event keeps the last reference to it).
Make it sure that the libinput_device is destroyed in the input thread,
before giving away the last extra input device references.

There was an attempt to remove an unnecessary inclusion of a header
file, but only got so far as compile testing after having commented out,
but didn't remove the comment before creating a commit. This commit
fixes that mistake.

Add a new ClutterPaintNode parameter to the paint_target() vfunc.
For now, create a temporary ClutterEffectNode that is passed to
paint_target() and immediately painted; next commits will move
this to upper layers.

To find XWayland output that should be the primary one, iterate through all
XWayland outputs, and compare their geometry to the geometry of the primary
logical monitor.
To avoid possible race conditions (Mutter's monitor configuration already
updated, but Xrandr not yet), set the output both after Randr notifications and
after 'monitors-changed' signal.

When we're running under a polyinstantiated SELinux environment, we'll
likely start with an isolated and empty /tmp, meannig no /tmp/.X11-unix
directory to add things to. To make it possible to still function in
this kind of setup, make sure said directory exists.

Instead of using native backend platform data specifically, store
this info in ClutterMotionEvent. This includes time in usec since
it's just used for motion events, in the future it could make sense
to make these general to all events again, but it could make sense
to make ClutterEvent structs private before.
In order to express that a motion event has relative motion info,
the CLUTTER_EVENT_FLAG_RELATIVE_MOTION event flag has been added
for it.

We had code in both backends that sort of independently associated
sequences to slots. Make both transform slots to sequences the same
way, so they may share the implementation convert those back to slots.
This helper now lives in Clutter API.

We have this as platform-dependent data in the native backend, and
a bunch of fallback code done in place in the evcode users. Stop
making this platform-dependent data, and move it to the relevant
ClutterEvents.
The fallback code for the X11 backend case is about the same, but
now it is done directly by the X11 backend.

Making this an event is overly convoluted, accounting that we
emit the event, then convert it to a ClutterStage signal, then
its only consumer (a11y) sets the active ATK state.
Take the event out of the equation, unify activation/deactivation
of the stage in MetaStage, and use it from the X11 backend too.

It was a test case in the Wayland test client directory, but it wasn't a
Wayland test client but a standalone test linking to libmutter. Since it
uses rlimit to implement certain aspects of the test, it can't be made
part of the regular unit tests, as that means any test running after
being stuck with the rlimit set, thus keep it standalone, but at least
run it as part of the test suite.

The XIOErrorExitHandler expects (Display *, void *) whereas mutter uses
(Display *, MetaX11Display *).
That causes a warning at build time:
warning: passing argument 2 of ‘XSetIOErrorExitHandler’ from
incompatible pointer type [-Wincompatible-pointer-types]
813 | XSetIOErrorExitHandler (xdisplay, x_io_error_exit, display);
Actually, the MetaX11Display is not even used, so we can just use the
expected API and ignore the value.
