The 'suspend state' is meant to track whether a window is likely to be
visible any time soon. The hueristics for this are as follows:
* If a window is hidden, it will enter the 'hidden' state.
* If a window is visible, and unobscured, it will enter the 'active'
state.
* If a window is visible, but obscured by another window, it will enter
the 'hidden' state.
* If there is a mapped clone of a window, it will enter the 'active'
state.
* If the window has been in the 'hidden' state for 3 seconds, it will
enter the 'suspended' state.
This will eventually be communicated to Wayland clients so that they can
change their behaviour to e.g. save power.

This are called when a clone directly attaches to an actor. While not
reliable to know whether a particular actor is cloned or not, one can at
least this way get notified about whether an actor in particular is
cloned.
This can be useful for e.g. the MetaWindowActor, as it's what's most
likely cloned, e.g. for alt-tab views etc.

Adds va_marshallers to the ClutterStage signals. This allows for better
stack traces to be retrieved when profiling. Additionally, since the
generic marshaller was using GBoxedCopy/GBoxedFree functions for the
GValue usage, the previous code was acquiring a global reader/writer
lock in GObject via g_boxed_free() usage.
With G_SIGNAL_TYPE_STATIC_SCOPE, the generated marshallers can avoid
the additional copy/free on the instance.

Previously it transformed a physical CRTC coordinate to a logical desktop
coordinate. But current and future users of the function all require
conversion from logical coordinates to physical coordinates. We would have
had to always invert the transform parameter which is a waste of time when
we can instead just invert the function behaviour.
We also simplify the parameters to show both the point coordinate and the
area dimensions are potentially transformed.

Same reasoning holds than with touchpad gesture events in the
previous commit, this will be the first event seen from a specific
device and will require early handling, or crashes may follow.

With commit be3bca01a7 in place, we now possibly skip early calls
to clutter_stage_repick_device() happening early during initialization.
These were also indirectly the ones that eventually ended up in
the first call to clutter_stage_pick_and_update_device() actually
initializing the PointerDeviceEntry.
With this no longer happening, we may end up with no PointerDeviceEntry
implicitly set up after initialization, which may fail if the first
event received from the seat pointer does not in fact trigger the
clutter_stage_pick_and_update_device() call necessary to make things
work from there on.
And this does indeed happen on touchpads, since the first input event
obtained after CLUTTER_DEVICE_ADDED is CLUTTER_TOUCHPAD_* instead
of CLUTTER_MOTION. This finds an unset PointerDeviceEntry and crashes
since the pointer device does still have no "presence" on the stage.
Fix this by making CLUTTER_TOUCHPAD_* events also trigger a
device update, so the fist event handled does always trigger the
necessary device update.

This data is commonplace enough that it makes sense to keep it
as generic event data. Make these fields take a hard refcount, like
the private data used to do, and drop these fields from the
ClutterEventPrivate struct.

When creating a new stream, check if the preferred format is
different from the default (COGL_PIXEL_FORMAT_BGRX_8888). If
it is, then also include it in the list of potential formats
for the stream.
COGL_PIXEL_FORMAT_BGRX_8888 is still passed around as it's
both the default, and the fallback for when things go wrong.
When creating buffers, use the negotiated SPA format instead
of a hardcoded value. We leave it to PipeWire to figure out
what's the best format, since clients may not support the
preferred format of the stream.
Due to how chaotic things got, this commit also cleans up
the create_pipewire_stream() to use an auxiliary array of
SPA formats, which is then iterated on in order to generate
the format pods.

In future commits, we will want to create DMA-BUFs with pixel
formats other than COGL_PIXEL_FORMAT_BGRX_8888. In preparation
for that, let's start passing a new pixel format parameter to
this function, and the corresponding winsys vfunc.
All callers of this function pass COGL_PIXEL_FORMAT_BGRX_8888
for now. Next commits will change that.

Freeing the window opaque region rather than the frame one when was
leaking the frame opaque region and wrongly setting the window opaque
region to NULL.

This is something the compositor could now track by itself, instead of
being pushed through events. It also makes more sense to do this directly
when the grabbing conditions change, as opposed to the next event.

Except for the tests that launches `mutter`, use a custom shell
implementation. It's roughly a copy of default.c with some cleanups on
top. A custom shell allows for a bit more freedom when doing testy
things.

The device/sequence may not currently have a set of coordinates to return.
We correctly leave the out values uninitialized, but don't tell the upper
layers in any way.

F39 has been branched, so we can use it as base of our CI image
and reduce the number of custom built components.
This will also help if gjs adds support for import maps and
gnome-shell bumps its gjs dependency to use it, as F39
already includes the new mozjs version that gjs now uses.
