This looks like a relic of glReadPixels-based picking, the pointer
might well be outside redrawn areas, yet still require a device
update (e.g. in order to reflect the actor layout changes in the
"clear area" info).
Instead, always update all devices that are inside the view after
relayouts, the tracking on the need for that update is now done
on each ClutterStageView, instead of globally in the ClutterStage.
This theoretically fixes situations where pointers might miss
updating their "clear area" after the actor tree changed.

When using Xwayland-on-demand (default), if the (experimental) autoclose
features is enabled, we can rely on Xwayland's auto-terminate feature
instead of explicitly killing the Xwayland process.
With it, gone is the mechanism that was added to check the X11 clients
connected and their executable to check whether we can (safely) kill
Xwayland.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1794>
The connection to the Xserver for the X11 window manager part of mutter
even on Wayland may prevent the Xserver from shutting down.
Currently, what mutter does is to check the X11 clients still connected
to Xwayland using the XRes extension, with a list of X11 clients that
can be safely ignored (typically the GNOME XSettings daemon, the IBus
daemon, pulseaudio and even mutter window manager itself).
When there is just those known clients remaining, mutter would kill
Xwayland automatically.
But that's racy, because between the time mutter checks with Xwayland
the remaining clients and the time it actually kills the process, a new
X11 client might have come along and won't be able to connect to
Xwayland that mutter is just about to kill.
Because of that, the feature “autoclose-xwayland” is marked as an
experimental feature in mutter and not enabled by default.
Thankfully, the Xserver has all it takes to manage that already, and
is even capable of terminating itself once all X11 clients are gone (the
-terminate option on the command line).
With XFixes version 6, the X11 clients can declare themselves
"terminatable", so that the Xserver could simply ignore those X11
clients when checking the remaining clients and terminate itself
automatically.
Use that mechanism to declare mutter's own connection to the Xserver as
"terminatable" when Xwayland is started on demand so that it won't hold
Xwayland alive for the sole purpose of mutter itself.

This is to get support for the “-terminate delay” option in Xwayland
with libXfixes 6.0.
libXfixes 6.0 provides the new ClientDisconnectMode that clients can
use to declare themselves as to-be-terminated.
This can be used to let Xwayland terminate itself automatically when no
other (“non-terminatable”) X11 client is left.

Adding a <dbus/> element containing a boolean (yes/no) determines
whether org.gnome.Mutter.DisplayConfig ApplyMonitorsConfig will be
callable. The state is also introspectable via the
ApplyMonitorsConfigAllowed property on the same interface.
For example
<monitors version="2">
<policy>
<dbus>no</dbus>
</policy>
</monitors>
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2030>
The test aims to verify that setting the following policy
<policy>
<stores>
<store>system</store>
</stores>
</policy>
only applies monitor configurations from the system level.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2030>
This adds a way to define a way, at the system level, to define a policy
of how monitor configuration files are loaded.
The intended use case is to e.g. either prefer system level monitor
configurations before user levels, or only allow system level
configurations.
Examples:
Prefer system over user level configurations:
<monitors version="2">
<policy>
<stores>
<store>system</store>
<store>user</store>
</stores>
</policy>
<configuration>
...
</configuration>
</monitors>
Only allow system level configurations:
<monitors version="2">
<policy>
<stores>
<store>system</store>
</stores>
</policy>
<configuration>
...
</configuration>
</monitors>

strncmp() always return 0 if the passed length is 0. What this means is
that whatever the first string check happens to be, if the parsed XML
cdata was empty (e.g. if we got <element></element>), the first
condition would evaluate to true, which is rather unexpected.
Fix this by making sure the string length is correct first. Also move it
into a helper so we don't need to repeat the same strlen() check every
time.

The way device backends implement power saving differ, and power saving
needs to contain nothing incompatible in the same update. Make it
impossible to e.g. mode set, page flip, etc while entering power save by
not using MetaKmsUpdate's at all for this.

When we're predicting state, i.e. when having posted an update while
avoiding reading KMS state, copy the predicted state, update the actual
state, and check that the predicted state matches the newly updated one.

It was a bit scattered, with it being split between MetaKms and
MetaKmsImpl, dealing with MetaKmsDevice and MetaKmsImplDevice
differentation. Replace this by, for now, single entry point on
MetaKmsDevice: meta_kms_device_process_update_sync() that does the right
thing.

As other KMS tests, depends on being DRM master and vkms being loaded.

Right now gamma is set only via the D-Bus API (from gsd-color), but the
actual gamma isn't right after SetCrtcGamma(), meaning if one would call
GetCrtcGamma() right after setting it, one would get the old result.
Avoid this by getting the "current" CRTC gamma from the cache we manage.

In order to support dynamic imports, gjs added an implicit mainloop
that can drive the main context independently from other mainloops
like the one from GApplication or MetaContext.
That means that sources can now get dispatched to the main context
from the moment the plugin is started, resulting in a crash as the
association between compositor and plugin manager doesn't exist until
meta_plugin_manager_new() returns.
Make sure this doesn't happen by only starting the plugin after
meta_plugin_manager_new() has returned.

The code style in the remote-desktop API is currently a mess.
While, the overall code style in mutter and gnome-remote-desktop is to
use spaces as tabulator, the remote-desktop API is mixed with both
spaces as tabulators and actual tabulators.
In addition to that, the code style in the XDG desktop portal APIs uses
spaces as tabulators as well.
To unify the code style, replace all actual tabulators with spaces.

When privacy screen is changed and this happens on explicit user request
(that is not a setting change) we should notify about this via an OSD.
To perform this, we keep track of the reason that lead to a privacy
screen change, and when we record it we try to notify the user about.
When the hardware has not an explicit hotkey signal but we record a
change we must still fallback to this case.
