This is similar, but reserved for the crossing events induced by the
input shape changes on our overlay window. The mechanism in the previous
commit does again protect against this, so this mechanism may go away.

Focus follows mouse is meant to avoid focusing windows that happened
to pop up under the pointer, e.g. due to mapping, workspace changes,
etc... On X11, this has been done since ancient times through a
moderately complex synchronization mechanism, so mutter would know
to ignore crossing events caused on those situations.
This mechanism is much prior to XInput 2 though, where we may know
this in a more straightforward way: If the sourceid of the crossing
event is a logical pointer (i.e. equals deviceid), the crossing event
was triggered logically, and not through user input.
Perform this simpler check, and drop the existing mechanism to
ignore logically induced crossing events.

The virtual stream source with CURSOR_MODE_EMBEDDED uses
META_STAGE_WATCH_AFTER_PAINT as the callback for recording its frame. In
this stage of the paint though, there is no ClutterPaintContext anymore
(there only is a paint context during the paint, not afterwards).
The callback (actors_painted()) tries to get the redraw clip from the paint
context, and we end up with a NULL pointer crash.
We actually do still have a redraw clip at this point, so because everyone
uses the paint context to get the redraw clip anyway, just pass the redraw
clip to the stage watches directly.

After an event has been handled such that it bypasses both Clutter and
Wayland, e.g. when handling a keybinding, bypass_clutter would get
unset in the presence of a wayland grab. This means that the event is
handled both as a keybinding and by Clutter.
In the case of switcher popups in gnome-shell in the presence of a gtk4
autohide popover this meant that instead of selecting the next element,
it would select the one after that. If there are only two elements, as
is common with input sources, this would mean going back to the current
one, preventing switching them with a single press of the keybinding.

When a device is added, libei does not allow adding additional regions
for that particular device, as it is already advertised to the EI
client.
As a result, mutter currently effectively only adds the first region to
a device, but not the others.
This makes input in multi monitor sessions only possible on one monitor,
as the EI client cannot look up the other regions, since they were not
advertised to it.
Fix this situation by not adding and resuming the device, when a shared
device is used.
Instead, for shared devices, always add all regions first, and then
after that, add and resume the device.

Use the previously added API to release acquired mapping ids, when the
corresponding stream is destroyed.
Otherwise, the remote desktop session would maintain a whole bunch of
unused mapping ids, as their corresponding streams are already
destroyed, but maybe not the session.
Such situation would be a remote multimonitor session, where the amount
of used virtual monitors changes multiple times during the session.

The remote desktop session currently provides a mechanism to acquire
mapping ids.
However, when they are not used anymore, they currently cannot be
removed and thus just linger around.
So, add an API to release these acquired ids.

Avoid passing the MetaSeatImpl, since it may be potentially null at
MetaSeatNative construction time. An example of this triggering issues
are mousekeys, since those work on an emulated pointer device created
indirectly after a keyboard device is added (and the right settings are
enabled) at a time that the MetaSeatImpl is still being created, so the
MetaSeatNative cannot yet have a reference to it.

These objects already have a pointer to the ClutterSeat that has a
pointer to the MetaSeatImpl in its native implementation. This data
may be considered pretty much immutable (a pointer to the seat is
held, and the native implementation will shut down the implementation
thread within ClutterSeat finalization.
Avoids some awkward code, since the MetaInputDeviceNative needs to
be aware of the Clutter object implementation and the implementation
object.

vc4's implementation of `drmModeAtomicCommit` seems to require a few
milliseconds advanced notice or else it will miss the frame deadline.
That's too high for our deadline evasion threshold which is measured
in microseconds. Let's stop trying to use deadline timers on vc4 to
avoid this conflict without having to disable atomic KMS.

When CLUTTER_ENABLE_DEBUG is not defined, then CLUTTER_NOTE is defined
as an empty block of code. As a result of that, jitter_us is in that

It's the 10 bit equivalent to NV12 and uses the same layout as P016, i.e.
16 bit components with the lowest 6 bits set to 0 (padding), allowing us
to use 16 bit "subformats".
Thus adding support is quite trivial as we can reuse the NV12 shader.
The format is widely supported in decoding and display hardware (on Intel
since Kaby Lake), as well as modern codecs (AV1, VP9, HEVC) and has
visible quality advantages over NV12.
Note that the additional colors are lost if composited to a 8 bit RGB
framebuffer. Switching between direct scanout and compositing can thus
cause quality differences. This is no new phenomena, however, as the
same is the case already for e.g. GL clients using 10 bit formats -
including video players.
Also note that P012 and P016 could trivially added as well - it's not
done here as they are uncommen and thus hard to test.

These shaders can be used for similar formats with other component
sizes since the values are represented as floats. So whether the source
value was stored in 8bit, 10bit or 16bit doesn't matter - the driver
will covert it for us.
Thus use a Weston-inspired, more general naming scheme.

They are needed as "subformats" for higher bit YCbCr formats, such as
P010, and we don't plan to use or expose them otherwise. Thus don't
implement any conversion or packing features.

Realizing a cursor will assume view related state objects are valid so
they can mark them as dirty. This assumption broke when there were a
scale changed that happened with multiple CRTCs, as we'd create view
object by view object as we realized the texture. Realizing the texture
would trigger a signal that had the handler assuming the validity of all
view objects, but if we only had gotten to the first, the second view
would not be there yet, thus we'd be doing a NULL pointer dereference.
Creating the view objects first, then handling the updating avoids this
problem by making the already done assumption valid on hotplugs.
The test case added tests exactly this series of events, and uses a
virtual monitor as a cheap trick to make the KMS CRTC based view the
first one, and an arbitrary view the second that previously had its view
object initialized too late.

The cursor surface is decided by the "current" surface; if that alone
changed (e.g. current surface was destroyed), we didn't update the
cursor, meaning it either got stuck, or got hidden if the client exited
completely.

It's hard to tell why turning on HDR mode failed without these log
messages. It could be missing support in the sink (EDID/DisplayID) or
missing support in the driver/display hardware (connector properties) or
just a failure turning it on.

Or else `glXQueryDrawable` will fail per the `GLX_EXT_buffer_age` spec:
> If querying GLX_BACK_BUFFER_AGE_EXT and <draw> is not bound to
> the calling thread's current context a GLXBadDrawable error is
> generated.
This mistake went unnoticed until `mtk_x11_error_trap_push` was introduced
(55e3b2e519) because for some reason it is incapable of trapping
`glXQueryDrawable`. Prior to that it seems
`cogl_onscreen_glx_get_buffer_age` would trap and so always returned zero.
This means we're reenabling clipped redraws on X11 here for the first
time in a long time.

Apart from a few edge cases we can avoid walking the tree and transform
to the ancestor coordinate space by multiplying the actor stage-relative
matrix with the inverse of the ancestor's stage-relative matrix.
Since the stage-relative matrices are cached, this reduces the number of
matrix multiplications we do in many situations considerably.
