Delay the addition and removal of devices using ClutterDeviceEvent's so that
they are processed following the libinput event order, and that we don't
have to flush the events on removal.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1371
When a device is removed from the seat the events that this device may have
emitted just before being removed might still be in the stage events queue,
this may lead a to a crash because:
Once the device is removed, we dispose it and the staling event is
kept in queue and sent for processing at next loop.
During event processing we ask the backend to update the last device
with the disposed device
The device is disposed once the events referencing it, are free'd
The actual last device emission happens in an idle, but at this point
the device may have been free'd, and in any case will be still disposed
and so not providing useful informations.
To avoid this, once a device has been added/removed from the seat, we queue
ClutterDeviceEvent events to inform the stack that the device state has
changed, preserving the order with the other actual generated device events.
In this way it can't happen that we emit another event before that the
device has been added or after that it has been removed.
Fixes: https://gitlab.gnome.org/GNOME/mutter/-/issues/1345
Clutter device events are special events coming from the backend when an
input device is added or removed.
When such events are processed, we should make the seat to handle them by
calling vfunc that can be implemented by each backend and eventually
emitting the appropriate signal.
If a device is removed, we can also safely dispose it, as it can be
considered stale at this point.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1371
Add clutter device added and removed events to allow processing of them as
it happens in the backends, queuing them and performing actions in order.
This allows not to loose any event that is performed just before removing or
disabling a device, and still process the events in order in the event
queue.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1371
When removing a device that has been just marked as the last in use, we may
try to notify that a NULL device is the last one.
This is not supported, as both update_last_device() and the clients of the
"::last-device-changed" signal are assuming that the last device is always
a valid ClutterInputDevice.
So let's avoid erroring, and stop the idle when clearing the current device.

This was from the old clutter-as-application-library days, where it had
to try find a suitable backend. Now we already have a backend selected
(MetaBackend), and the clutter backend is already predecided depending
on that, so we don't need the code that auto detects an appropriate one
anymore.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1364
We're moving towards not supporting stand-alone application style
clutter stages, meaning the stage tests use will be reused instead of
recreated. To make this feasable, tests must clean up after themself.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1364
meta_run() is still left intact and does the same as before; the new
functions are only intended to be used by tests, as they may need to set
things up after starting up. Doing so linearly in the test case is much
easier than adding callbacks, so meta_run() is split up to make this
possible.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1364
There is no reason to use Xsettings for the X11 backend, as it comes
from the GSetting store anyway, so move the font setting reading to
ClutterSettings and read directly from GSettings.

The delete event was used for signalling the close button was clicked on
clutter windows. Being a compositor we should never see these, unless
we're running nested. Remove the plumbing of the DELETE event and just
directly call meta_quit() when we see it, if we're running nested.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1364
We checked if we were using the usig the X11 backend to decide when to
deal with a11y event posting - in order to make the clutter code less
windowing system dependent, make this check a check whether we're a
display server or not, in contrast to a window/compositing manager
client. This is made into a vfunc ot ClutterBackendClass, implemented by
MetaClutterBackendNative and MetaClutterBackendX11.

Test that if a timeline got its frame clock from a parent of the
associated actor, if that actor moves across the stage so that the stage
views changes and thus the would be picked frame clock too, this is
noticed by the timeline so that it also changes to the correct frame
clock.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1404
Timelines where the frame clock was picked from a parent of the
associated actor didn't get notified about any stage views changes, as
it only listened on the associated actor. If that actor didn't actually
get its stage views changed (because it went from empty to empty), we'd
end up with a stale frame clock, leading to crashes.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1404
When we pick the frame clock given the associated actor, that frame
clock in fact comes from a picked actor. In order to not end up with
stale frame clocks, which may happen on e.g. hotplugs, monitor layout
changes, or non-optimal frame clocks, which may happen when the parent
used for picking the clock moves to another view, lets listen to
'stage-views-changed' on the actor used for picking the clock too.

Flip flop resize, which is the result of respecting ConfigureNotify
makes test annoyingly racy, as one cannot do
clutter_actor_set_size (stage, 1024, 768);
wait_for_paint (stage);
g_assert_assert (clutter_actor_get_width (stage) == 1024);
The reason for this is any lingering ConfigureNotify event that might
arrive in an inconvenient time in response to some earlier resize.
In order to not risk breaking any current behavior in the X11 CM case
(running as a compositing window manager), only avoid changing the stage
size in response to ConfigureNotify when running nested.

Let's not expose that outside of mutter quite yet; it's not used in
gnome-shell, and to avoid future breakage if it starts to be used, lets
move it to clutter-mutter.h so only mutter and clutter itself can use
it.

This aims to make sure a view and its resources are destroyed when it
should. Using references might keep certain components (e.g frame clock)
alive for too long.
We currently don't take any long lived references to the stage view
anywhere, so this doesn't matter in practice, but this may change, and
will be used by a to be added test case.

In order to run gnome-shell as part of the CI pipeline, we need
an additional runtime dependency plus python3 modules to mock
required system services and run gnome-shell-perf-tool.

Just as wl_shm, hook up the Wayland DMA-BUF protocol to the 64 bit half
point pixel formats too. This makes it possible for Wayland EGL clients
to use 64 bit pixel EGL configurations.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/804
Now that cogl understands them, hook wl_shm up so they can be used.
This also bumps the wayland-server version dependency to 1.17.90, which
corresponds to the master branch of wayland. The new formats will be
available in 1.18.0.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/804
In order to support the DRM formats DRM_FORMAT_ABGR16161616F and
friends, as well as the wl_shm formats WL_SHM_FORMAT_ABGR16161616F and
friends, cogl needs to have knowledge about said formats too.
We don't have a software implementation of the half point data types
however, so the pack/unpack methods remain unimplemented. We don't need
them for now, so it's not crucial that we add them.
For the GLES2 driver, currently only two formats are supported, and
since we don't currently have pack/unpack implementations, the other
formats will for now remain unsupported, until we have a half float
implementation.

Without doing this, we'd use the same sprite that was last set by
mutter, most likely a leftptr cursor, and fail to update when e.g.
moving the pointer above a text entry and the displayed cursor updated
to a cursor position marker.
