When cloning an actor we were applying a global scale to it, based on
the size of the clone itself and of the cloned actor.
This implied that the transformed size of the clone was not the one that
was set, but it was taking taking in account the actor scaling too.
So in practice we were scaling it twice.
While this had no visual implications it indeed was causing troubles
when a ClutterClone was reactive because in such case only the scaled
area of the scaled clone was considered reactive.
Assume you had an actor of 100x100 pixels, scaling it to a clone of
50x50 pixels:
- The scale applied to the clone was 0.5
- The transformed size of the clone was: 25x25 pixels
- The clone was reactive only in that sub-area
To avoid this, never touch the clone transformation matrix, but only
transform it at paint time.

We were leaking one instance because _cogl_winsys_egl_context_created()
could be potentially be called twice (via cogl_display_setup() one as
part of cogl_renderer_check_onscreen_template() and the other when
called from clutter_backend_do_real_create_context()), and so we'd ended
up overwriting the reference we had.
However, we really didn't use it anywhere and once used to call the
relevant functions it's just useless.
So let's just keep it as local variable

We were leaking the color profile path keys but also it wasn't clear how
the ownership was passed to the new hash-table, so let's just remove it
from the pending hash table and add it to the new one including the
expected reference.
This is safe because we were still adding a temporary extra ref to the
profile

The cursor was following the "current" surface (i.e. the logical
focus, unaffected by e.g. grabs), so MetaWaylandPointer was always
providing window cursors, just so the MetaCursorRenderer would maybe
discard them and show the compositor cursor instead. E.g. in the
presence of grabs.
This clear barrier between grabs being compositor business deserving
a compositor cursor, and non-grabs being client business turned a bit
blurrier in grabs-pt5 where "client" things like popups and DnD would
also involve grabs. The fixes in that regard in the branch went on
the lenient side, introducing situations where grabs do exist but we
are preferring client-side cursors anyways.
Fix this by making MetaWaylandPointer aware of grabs at the time of
updating the client-side cursor, by following the "focus" surface
(i.e. the effective focus, affected by grabs outside of MetaWaylandInput).
The focus surface and cursor will be updated on focus changes, also
induced by grab changes.

In some cases, reparenting a window with its frame may fail; this seems
to happen especially during initialization of a window that may be
unmapped and re-mapped quickly and multiple times.
If this happens, we're never going to receive a remove event on the
stack tracker and so we may end up adding it twice to the list of the
windows to synchronize with the compositor, breaking its assumption that
the stack list is unique, and eventually leading to a crash because we
do not end up removing all the instances of a window on its destruction.
In particular we may end up in this situation:
Syncing Window 10485927: 0x555558863540 (actual xid is 10485927),
user time is 10485928 frame is 0x5555588715c0, frame xid 6291591
Syncing Window 14680081: 0x5555588664b0 (actual xid is 14680081),
user time is 14680082 frame is 0x555558871d80, frame xid 6291595
Syncing Window 6291460: 0x55555796dc80 (actual xid is 10485763),
user time is 10485764 frame is 0x555557a6f630, frame xid 6291460
Syncing Window 6291465: 0x555557a68af0 (actual xid is 14680067),
user time is 14680068 frame is 0x555557a73e80, frame xid 6291465
Syncing Window 6291509: 0x555557f9d830 (actual xid is 8388623),
user time is 0 frame is 0x555557fac780, frame xid 6291509
Syncing Window 6291586: 0x5555586e1690 (actual xid is 4194363),
user time is 0 frame is 0x55555886e550, frame xid 6291586
Syncing Window 6291591: 0x555558863540 (actual xid is 10485927),
user time is 10485928 frame is 0x5555588715c0, frame xid 6291591
Where the same meta window 0x555558863540 is added twice because that's
both mapped by the window itself (10485927) and by its frame (6291591).
This happens because for historical reasons the xids hash table managed
by the x11-display maps both the X11 windows, their frames and their
user time windows as the meta-window, and so if we don't filter out them
properly we end up duplicating the entries in the compositor list.
Such duplicates finally end up making mutter to crash in
meta_compositor_sync_stack() because we could end up trying to access
to an invalid window, given its actor has been destroyed but not all the
instances have been removed from the compositor windows list:
0x00007ffff71059 in meta_compositor_sync_stack (compositor=0x555555b8,
stack=0x555558701b80) at ../../mutter/src/compositor/compositor.c:773
773 if ((old_window->hidden || old_window->unmanaging) &&
(gdb) print old_window
$1 = (MetaWindow *) 0x0
So, in order to prevent this, check that XReparentWindow does not fail,
and in case of failure, reset the window state to the one it had before
we failed and more importantly, remove the association between the frame
X11 window and the MetaWindow, since this is not true anymore and so
that at the next stack synchronization there won't be any meta window
associated to that frame XID (unless there aren't further stack changes
impacting on that). Without this we would have instead waited for the
remove event that we predicted, but that could never happen because no
ReparentNotify is emitted in such case.

Since we listen the X events in the same thread, and they are delivered
through the main loop, there's not any need to set the frame details on
windows before the reparent operation, because such action could fail.
So move the code order, as preparation for handling the error.

That was only there to force updating MetaFrame's bounds
but that is something that is already updated in
MetaWindowX11.move_resize_internal. So just drop all of that

Since the `switch` didn’t have a default case, the `cull_front` and
`cull_back` variables could technically be used uninitialised if the
`cull_mode` was unrecognised.
That seems unlikely to happen as presumably other code makes sure the
`cull_mode` is valid, but it doesn’t hurt to add a `default:` case to
squash the compiler warning.

Depending on whether the input mapper was found, these variables could
indeed be used uninitialised, so this is a true positive warning.

In the future, the module will automate uploading the release
tarball. We already use the CI pipeline to generate the tarball,
so it's easy to hook up the module and provide some testing
before the module goes into production.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3775>
We currently assume that the `CI_COMMIT_TAG` variable matches the
version component of the generated dist tarball.
That is usually correct, but sometimes errors happen and a wrong
tag is pushed, and the real release uses something like "46.0-real".
Account for that by building the artifact path from `meson introspect`
and exporting it as environment variable.

For a Wayland only build, we would like to avoid linking against
libXcursor which on it turn, links back to some of the X11 deps.
In order to achieve that, we include a small subset of xcursor.
In case Mutter is built with X11 or with both Wayland & X11, we link
against libXcursor and don't make use of the in-tree implementation.
This patch mimics what GTK 4 do by shipping an in-tree copy of xcursor.
Especially that libwayland-cursor does not provide an alternative to
xcursor itself.

When meta_wayland_pointer_constraint_remove() is called, it can trigger
a meta_wayland_event_handler_invalidate_focus() via:
meta_wayland_pointer_constraint_destroy()
meta_wayland_pointer_constraint_disable()
meta_wayland_input_detach_event_handler()
meta_wayland_input_invalidate_all_focus()
meta_wayland_event_handler_invalidate_focus()
Which then would result in a "focus-surface-changed" signal which would
call meta_wayland_pointer_constraint_remove() a second time. This
happens after surface_remove_pointer_constraints() has already been
called in the first meta_wayland_pointer_constraint_remove() call,
leading to "data" being NULL.
To prevent this issue disconnect the signal handler before calling
meta_wayland_pointer_constraint_disable() when destroying a constraint.
