This is a strange thing to do since MetaInputMapper also does take care of
devices with an output configured through settings, since we might have
devices that were configure through settings exclude other devices that
belong together with an output (e.g. a display-integrated tablet).
This was essentially here as a last resort to avoid matching two very
similar looking tablets to one of two very similar looking outputs. There
was a 50% chance already that the choice was wrong, and now these devices
can all be configured specifically through settings, so this shouldn't
be missed either.

Non-display-attached tablets (e.g. Intuos) may find no match, which
should mean "use the span of all monitors", not "pick one for me".
Reserve this fallback to touchscreen devices, since these might
still benefit from it.

The matrix and aspect ratio of the tablet is irrelevant on pads, and
it actually triggers warnings when trying change that on those devices:
gnome-shell:42536): mutter-CRITICAL **: 17:22:41.994: meta_input_device_native_get_mapping_mode_in_impl: assertion 'device_type == CLUTTER_TABLET_DEVICE || device_type == CLUTTER_PEN_DEVICE || device_type == CLUTTER_ERASER_DEVICE' failed
This is unnecessary to do on pad devices, these just need to be moved
together with their respective stylus.

In the case a11y is required, the screen reader is very much
interested in getting an uninterrupted flow of key events. It attempts
so by setting a ::captured-event callback on the ClutterStage, but
that falls short with our MetaDisplay event handler, as clutter events
can be stopped before a11y gets a chance to see them.
This kind of selective amnesia wrt key events is not new, in X11 those
go unheard of by the WM as long as a client is focused and no grabs hold,
so it is clients' responsibility to talk with AT bridge.
This commit doesn't yet change that for X11, but we can do this right
away from the compositor on Wayland, and without any chance to be
tampered by clients.

Since the completion callback (on_switch_workspace_effect_complete) sets
priv->tml_switch_workspace1 to NULL, the unref was trying to unref NULL,
and the reffed ClutterTimeline was not getting unreffed.
This could be triggered by rapidly switching workspaces, switching again
before the animation of the initial switch was done.
Found while working on #2038.

The cursor renderer shouldn't assume all the CRTCs of a logical are KMS
CRTC's, as we'll end up checking hardware capabilities for CRTC's of
virtual monitors as well, when they were created to not embed the cursor
image directly in the framebuffer.
Instead, use the newly introduced API for checking CRTC cursor
capabilities. This fixes a crash with the following backtrace:

On a KMS backed CRTC, hardware cursor are supported when there are
cursor planes to assign them to. Note that when using legacy mode
setting, fake cursor planes are added when adequate.
On virtual CRTCs, used with virtual monitors, the equivalent of hardware
cursor are always supported, as they are sent using embedded PipeWire
stream metadata.

This can happen if a texture was newly assigned to the actor, but the
unobscured region hasn't been updated yet. Without bailing here, the
actor would display correctly via direct scanout, but other parts of
mutter would continue considering it obscured, which would e.g. result
in no frame callbacks getting sent for its surface.

Previously we chose to only anti-alias texels inside the boundary
(`clip_radius - 1.0`) but zoomed in you could see it was slightly smaller
than the correct curve (#2024).
Similarly if you choose to only anti-alias texels outside that edge
(`clip_radius + 1.0`) then you'd get an overly convex curve that doesn't
match up with the straight line sections.
So now we anti-alias texels that intersect the circle boundary, regardless
of which side they are mostly on. For efficiency we define "intersect" to
mean any texel whose center is within 0.5 of the theoretical edge.

It was dropping to zero after the first frame because it hadn't been
incremented high enough. So the second frame would crash with:
```
#0 g_type_check_instance_cast
#1 META_DRM_BUFFER
#2 copy_shared_framebuffer_cpu
```
That's the CPU-copy path (fallback-fallback) that probably no one is using
but it does work after this fix. Exactly the same issue as was fixed
in `copy_shared_framebuffer_primary_gpu` by 36352f44f9.

A client can create a token without any seat, serial, or surface. In
this case, we'd still try to grab, which would run into some unforseen
code paths, potentially resulting in the following crash:

When an activation times out, we'll be signalled two signals on the
startup sequence object: "timeout", and "complete".
Normally, the "complete" signal is emitted when a startup sequence is
completed succesfully by it being used for activation, and in this case,
the xdg_activation implementation should remove the sequence from the
startup notification machinery.
However, in the timeout case, we should not remove it, as the startup
notification machinery itself will deal with this. If we would, we'd end
up with use-after-free issues, as the sequence would be finalized when
removed the first time.
To avoid this, just clean up the Wayland side in the "timeout" signal
handler, leaving the "complete" signal handler early out if it was
already handled by it.
This avoids crashes like:
0) g_type_check_instance (type_instance=type_instance@entry=0xdd6740)

This test ensures that windows that were resized such that they extend
beyond the screen will be moved to be fully on the screen (if possible).
This has been working on X11 since forever, but on Wayland only since
the last commit.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2103>
The previous code was trying to detect client resizes by only
considering resizes without any pending configurations as client
resizes. There can however be pending configurations that do not involve
resizing, such as ones triggered by state changes. These may also stay
unacknowledged by the client until the next size change. This was
causing client resizes after showing the window (and therefore changing
its status to focused) to not be detected as client resize.
Fix this by checking whether the queue has any configuration with size
changes rather than just whether it is empty.

If some connectors disappeared, but the rest didn't change, we missed
actually removing the ones that disappeared, as we incorrectly assumed
nothing changed. Fix this by only assuming nothing changed if 1) we
didn't add any connector, and 2) we have the same amount of connectors
as before the hotplug event. The connector comparison checking makes
sure we report changes if anything of the still available connectors
changed.
