With EI support wired to XTEST, and oeffis being enabled in Xwayland
means that XTEST will always go through the XDG portal.
While this the intended behavior for the general use case of Xwayland
running rootless on a desktop compositor, that breaks when Xwayland is
running on a nested compositor, because the portal is for the entire
session and not limited to the nested Wayland compositor.
Enable XDG portal support in Xwayland only when we managed to connect
to the GNOME session manager, which means we are running in a full
desktop session, and not in any form of nested mode.
This is determined by simply using the status returned by set_gnome_env()
which will fail if not connected to a GNOME Session manager.

The function set_gnome_env() is used to pass environment variables
though DBus using the "org.gnome.SessionManager".
If that fails, it means we are not running in a full environment, which
might be useful to determine whether Xwayland should enable the portal
support.

Enabling portal support unconditionally breaks when running nested, so
Xwayland has now a new command line option to explicitly enable support
for XDG portal at runtime.
Check whether the version of Xwayland we are using has such an option.

When a configuration has a fractional scale, but we're using a physical
monitor layout, we can't use the scale, but if we do, we end up with
wierd issues down the line. Just discard the config if we run into this.
Eventually we probably want to store the layout mode in the
configuration so we can handle more seamless switching between physical
and logical layout mode, but first do this.

The surface actors may not have a valid allocation when running the
test. The preferred height, which `clutter_actor_get_size()` returns
in that case, can be wrong in certain cases, making us not add the black
background when it's actually needed.
Query the allocation instead, even at the expense of additional
relayouts.
While on it, sneak it some small cleanups.

The absolute modelview contains OpenGL coordinates, which have a higher
chance to not be invertible or, when doing so, introduce rounding
errors. These again often result in relative transforms becoming 3D
instead of 2D, making us miss optimized code paths down the line.
Thus cache stage-relative matrices instead, improving correctness and
possibly performance.
While on it also add some fast paths for cases where we can skip
calculating inverted matrices altogether and change variable names to be
more precise.

There's two aspects from its documentation
(https://xkbcommon.org/doc/current/group__state.html#gae56031a8c1d48e7802da32f5f39f5738)
affecting us here:
1. "This function is similar to xkb_state_key_get_syms(), but intended for
users which cannot or do not want to handle the case where multiple
keysyms are returned (in which case this function is preferred)."
We are indeed in that field, and have been for a long time.
2. "This function performs Capitalization Keysym Transformations."
This is unlike the xkb_key_get_syms() function that we use, and
convenient here for parity with X11 since it behaves exactly that
way.
Fixes cases where the keysym for some keys is not properly capitalized
when caps lock is toggled, due to the output of capslock+key being
different from shift+key. An example of this is 'é' in french(azerty)
layout (bound to the '2' key). Even though shift+2 outputs '2',
capslock+é should output 'É'.

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

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.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3244>
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.
