Require the "variable-refresh-rate" keyword under the
"experimental-features" gsetting to enable the feature for now.
It would no longer be required once the experience with variable
refresh rate is good enough for general use and handles all common
use cases well.

To paraphrase jadahl: we have a dedicated KMS thread now, which also
has realtime scheduling enabled unconditionally. realtime scheduling
on the main thread isn't too great of an idea, considering GC can
take a hot minute.
And to quote rmader: we most likely won't be able to make the main
thread rt as long as we use GJS and thus have GC.
So let's get rid of it! It's just been breaking things anyways.
This just ignores the setting; we'll fully remove it when GNOME 46
comes around.

This adds the actual input capturing rerouting that takes events and
first hands them to the input capture session, would it be active.
Events are right now not actually processed in any way, but will
eventually be passed to a libei client using libeis.
A key binding for allowing cancelling the capture session is added
(defaults to <Super><Shift>Escape) to avoid getting stuck in case the client
doesn't even terminate the session.
The added test case makes sure that the pointer moves again after
pressing the keybinding.

We now only enable DMA buffer based PipeWire screen casting if a
format/modifier has been negotiated. This practically means a consumer
is aware about what is needed, and we should not try to predict that it
uses the DMA buffer the right way (i.e. not mmap:ing directly).
However, in case we're not hardware accelerated, we never want to
attempt to use DMA buffer screen sharing, as we want to avoid
compositing into a DMA buffer on such hardware as doing so can be very
slow.

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.

Defining valid values makes
1. changing settings less error prone
2. sure they are discoverable.
This does reset the values once on update, but fortunately does *not*
change the way to set the values. Thus e.g. enabling fractional scaling
via terminal command still works as before and internet guides stay valid.

Closing automatically Xwayland once all relevant X11 clients are gone is
inherently racy, if a new client comes along right at the time we're
killing Xwayland.
Fixing the possible race conditions between mutter, Xwayland and the X11
clients may take some time.
Meanwhile, make that an experimental feature "autoclose-xwayland".

The check-alive feature is there for the user to be able to terminate
frozen applications more easily. However, sometimes applications are
implemented in a way where they fail to be reply to ping requests in a
timely manner, resulting in that, to the compositor, they are
indistinguishable from clients that have frozen indefinitely.
When using an application that has these issues, the GUI showed in
response to the failure to respond to ping requests can become annoying,
as it disrupts the visual presentation of the application.
To allow users to work-around these issues, add a setting allowing them
to configure the timeout waited until an application is considered
frozen, or disabling the check completely.

This commit adds basic screen casting and remote desktoping
functionalty. This works by exposing two D-Bus API services:
org.gnome.Mutter.ScreenCast and org.gnome.Mutter.RemoteDesktop.
The remote desktop API is used to create remote desktop sessions. For
each session, a D-Bus object is created, and an application can manage
the session by sending messages to the session object. A remote desktop
session the user to emit input events using the D-Bus methods on the
session object. To get framebuffer content, the application should
create an associated screen cast session.
The screen cast API is used to create screen cast sessions. One can so
far either create stand-alone screen cast sessions, or a screen cast
session associated with a remote desktop session. A remote desktop
associated screen cast session is managed by the remote desktop session.
So far only remote desktop managed screen cast sessions are implemented.
Each screen cast session may have one or more streams. A screen cast
stream is a stream of buffers of some part of the compositor content.
So far API exists for creating streams of monitors and windows, but
only monitor streams are implemented.
When a screen cast session is started, the one PipeWire stream is
created for each screen cast stream created for the session. When this
has happened, a PipeWireStreamAdded signal is emitted on the stream
object, passing a unique identifier. The application may use this
identifier to find the associated stream being advertised by the
PipeWire daemon.
The remote desktop and screen cast functionality must be explicitly be
enabled at ./configure time by passing --enable-remote-desktop to
./configure. Doing this will build both screen cast and remote desktop
support.
To actually enable the screen casting and remote desktop, the user must
enable the experimental feature. See
org.gnome.mutter.experimental-features.

Moved from g-s-d's media keys plugin, where it was called "video-out",
since it requires changing the current monitor configuration and we
want to remove the old DBus API.
This implementation is intentionally simple and not really meant for
more than debugging and validating the various configurations. A
better user experience will be introduced in gnome-shell with a custom
keybinding handler.
The default value includes <Super>P in addition to the standard keysym
for historical reasons.

We'll need to drop the old monitor configuration system to pave way to
better hi-dpi and multi-gpu support. Let's start by defaulting to the
new system in order to give it more real world testing.

This commit adds support for rendering onto enlarged per logical
monitor framebuffers, using the scaled clutter stage views, for HiDPI
enabled logical monitors.
This works by scaling the mode of the monitors in a logical monitors by
the scale, no longer relying on scaling the window actors and window
geometry for making windows have the correct size on HiDPI monitors.
It is disabled by default, as in automatically created configurations
will still use the old mode. This is partly because Xwayland clients
will not yet work good enough to make it feasible.
To enable, add the 'scale-monitor-framebuffer' keyword to the
org.gnome.mutter.experimental-features gsettings array.
It is still possible to specify the mode via the new D-Bus API, which
has been adapted.
The adaptations to the D-Bus API means the caller need to be aware of
how to position logical monitors on the stage grid. This depends on the
'layout-mode' property that is used (see the DisplayConfig D-Bus
documentation).

This gsetting will allow the adding of keywords to a array, where each
keyword may enable an experimental feauter, if the given mutter version
supports that particular experimental feature. Emphasis is put on the
lack of guarantee that any such keyword has any effect. Currently no
keywords are defined.

intltool is unmaintained nowadays while upstream gettext gained
support for formats like GSettings schemas and .desktop files,
and offers a mechanism to teach it about other XML formats not
yet supported out of the box which we can use for the rest.
So there's nothing stopping us, just make the switch ...
