Currently the only way to get cgroup for a MetaWindow is to get it's
PID and perform a bunch of file accesses and string manipulations.
This is especially not feasible if we want to get the cgroup every
time a MetaWindow has gained or lost focus.
A solution to this is to cache the GFile for a cgroup path.
The creation and access of this GFile is handled by
`meta_window_get_unit_cgroup` function.
`meta_window_unit_cgroup_equal` is a utility function which allows
us to compare whether two MetaWindows belong to the same cgroup.

commit c4a73e7950 added
code to cleanup the renderer when the meta backend is
disposed. Unfortunately, this introduced a crash when
the window manager is replaced.
This is because cleaning up the renderer involves talking
to the X server over a display connection that's closed
two lines higher as part of the clutter_backend_destroy
call.
This commit fixes the crash by swapping their order.

We fetch a frame clock that we schedule update on when queuing
_NET_WM_FRAME_DRAWN events. In some situations this frame clock is the
one from the stage, and if there are multiple hotplugs in a row, we
failed to update it as there were no stage views changes on the window
actor itself. As an actor updates the stage views list on layout, When a
queue_frame_drawn() call was done (typically from an X11 event) after a
second hotplug, it'd attempt to schedule an update on the frame clock
from the previous hotplug, as it didn't get notified about any
stage-views changes since for itself there was none.
Fix this by not caching the frame clock at all and just fetch it every
time.
In the majority of cases, this fetching means iterating over a very
short list (most often a single entry, rarely more), so it's very
unlikely to be of any relevance. The only situations where it might be a
heavier operation is the short time between a hotplug and a layout, as
it will attempt to traverse up to the stage to find a clock, but that's
likely only a few levels, so even that is unlikely to be an issue.

This was introduced by accident in commit 1467b6b02a
y-inverted textures in combination with shape masks appear to
be only commonly used with EGLstreams. However, as we draw the
shape mask ourselves, we don't want to apply the y-invert to it
as testified by the left over `cogl_pipeline_set_layer_matrix()`.
Note that we still allow to apply viemports and buffer transforms,
as the Xwayland mode setting emulation may use it (in fact only
the former, but it probably does not hurt to leave the later as well).

Monitor configuration check tests can be very complex and in case of
failures we can't easily catch where a failure happened without entering
in debug mode, something that isn't always an option in CI or external

So add more debug statements in configuration check functions and use
macros to ensure that we print the caller function and location on more
complex check functions.

Primary monitor is just the same of the other monitors, but it has a
primary monitor flag. Since the computation of the scaling isn't

configs list in order to properly compute the positioning.

When a selection owner advertises a mime type, but does not provide the
content upon a request for the mime type content, the requesting side
might wait indefinitely on the content.
To avoid this situation, add a timeout source, which will cancel the
selection transfer request after a certain timeout (15 seconds) passed.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1874>
Currently, if g-r-d closes the read end of the pipe for a
SelectionRead() operation, due to realizing that the application, that
should provide the mime type content, does not provide any content,
mutter won't notice that and still assumes that the read() operation
on the pipe in g-r-d is still happening, as mutter never writes to the
pipe in that situation and therefore cannot realize that the pipe is
already closed.
The effect of this is, that if g-r-d aborts a read() operation and
requests a new read() operation via SelectionRead(), mutter will deny
the request since it assumes that the previous read() operation is
still ongoing.
Fix this behaviour by also checking the pipe fd in mutter before
denying a SelectionRead() request.

With some resolutions (such as 4096x2160) we may compute duplicated
scale factors because we used a too wide threshold to check for an
applicable value.
In fact, while when we're at the first and last values it's fine to
search applicable values up to SCALE_FACTORS_STEP, on intermediate ones
we should stop in the middle of it, or we're end up overlapping the
previous scaling value domain.
In the said example in fact we were returning 2.666667 both when
looking to a scaling value close to 2.75 and 3.00 as the upper bound of
2.75 (3.0) was overlapping with the lower bound of 3.0 (2.75).
With the current code, the lower and upper bounds will be instead 2.875.
Adapt test to this, and this allows to also ensure that we're always
returning a sorted and unique list of scales (which is useful as also
g-c-c can ensure that this is true).
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1878>
We introduced META_MONITOR_SCALES_CONSTRAINT_NO_FRAC to get global scale
values however, this didn't work properly for some resolutions.
In fact it may happen that for some resolutions (such as 3200x1800) that
we did not compute some odd scaling levels (such as 3.0) but instead
its closest fractional value that allowed to get an integer resolution
(2.98507452 in this case).
Now this is something relevant when using fractional scaling because we
want to ensure that the returned value, when multiplied to the scaled
sizes, will produce an integer resolution, but it's not in global scale
mode where we don't use a scaled framebuffer.
So, take a short path when using no fractional mode and just return all
the applicable values without waste iterations on fractional values.

Scaling values computation code served us well in the past years but
it's quite delicate and it has some issues in edge cases, so add a test
that verifies that the computed scaling values for all the most common
resolutions (and some that may be common in future) are what we expect
to be.
This may also serve us in future when we'd define a better algorithm to
compute the preferred scale, but this not the day.

When deriving the global scale from current monitor, we were just checking the
supported value by the primary monitor, without considering weather the current
scale was supported by other monitors.
Resolve this by checking if the picked global scale is valid for all active
monitors, and if it's not the case, use a fallback strategy by just picking the
maximum scale level supported by every head.

In Xrandr we were caching the available scaling modes that were computed just
for the current mode, for each monitor, while we can actually reuse the
default implementation, by just passing the proper scaling constraint.
In monitor we need then to properly filter these values, by only accepting
integer scaling factors that would allow to have a minimal logical monitor
size.

Before we first created the MetaWaylandCompositor instance, which would
repare Clutter/Cogl so they could initialize and turn on Wayland display
