This aims to allow configuring the output luminance currently used via
the color state shaders. It will replace the output luminance property
of the debug control API.

This commit adds another way how to disable the a11y manager ACL in development.
Setting the unsafe mode might not be as straightforward as setting an
environment variable for the session, and you can control it invidually too.

This object will for now only provide a way for assistive technologies
to receive keyboard events, however it is expected that it will be used for
the new a11y communication protocol in the future.

Now with the new parsing mechanism we are able to set `Super` as
default for overlay-key. The parsing of the `Super` string will
fail at the new mechanism will kick in by appending `_L` and `_R`.
The parsing of the new two strings then will succeed and we will
be able to use both Super_L and Super_R to activate the overview.

HDR being enabled was controlled by toggling a property on
org.gnome.Mutter.DebugControl, which affected how the color space and
HDR metadata of the output was configured. Replace this with a higher
level MetaMonitor / MetaOutput level "color mode" enum, that is also
reflected in the monitor configuration API.
This enum is then used to derive the color space and HDR metadata at the
lower level where it matters. The ForceHDR debug control property is
still left there, as it only affects the color space and transfer
function of the view related to a monitor.

It will be used to force the color state of all monitors to be as if
they managed to turn on HDR mode. This is useful for debugging shaders
in an environment where an HDR mode capable display is not available,
such as the nested mode.

It is intended to replace using GetResources() and ChangeBacklight().
It moves from a normalized 1-100 numbers, to directly exposing the
hardware. This more closely maps to how gsd-backlight.c in
gnome-settings-daemon normally works, and simplifies the API a bit to
not have to deal with rounding issues.
There is still no KMS uAPI for this, so it still only hooks up to
XRANDR. Being private API, it doesn't try very hard to predict how the
KMS uAPI will look. When that day comes, it will likely need some
adaptations.
Part of the motivation here is to get something for gsd-backlight.c to
use where it can work more similarly to how the current common case
(sysefs) works, while attempting to migrate away from libgnome-rr.

With the next commits we'll introduce a new mode for scaling of Xwayland apps,
we'll want to put this mode behind an experimental setting though, so add
that setting.

This replaces the `legacy-ui-scaling-factor` entry in
`org.gnome.Mutter.DisplayConfig`, with the motivation being to no longer
expose X11 specific state via the monitor configuration API.

Add a new service client type for a filechooser portal client, and

Allow compositing in a linear color space and do so either when forcing
it via the debug controls D-Bus API, or when the experimental HDR mode
is enabled.
This relies on paint nodes etc to actually transform everything into the
linear target color space, which isn't done yet, so enabling it right
now will cause a broken result. Yet, introduce this now, so that
painting can be fixed piece by piece.
Linear blending is automatically enabled on monitors where HDR is
enabled, as this makes it possible to use an linear color space when
blending content from different color spaces with different transfer
functions.
Linear blending requires extra precision, i.e. 16 bit per channel
in the intermediate buffer due how the values are distributed,
so only enable the experimental HDR mode if the Cogl context supports
half float formats.
By default, no intermadiate linear offscreen framebuffer is used.
To test, do e.g.
./tools/debug-control.py --toggle ForceLinearBlending

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.

The debug controller can optionally, when passing --debug-control,
enable manipulating debug state, so far enabling/disabling HDR, via
D-Bus.
It's always created, in order to have a place to store debug state and
emit signals etc when it changes, but so far, it doesn't have its own
state it tracks, it just mirrors that of the monitor manager.

When a stream is destroyed by a consumer, mutter won't be able to
recognize that.
For mutter, the stream just paused, but did not disconnect, because the
connection state of a PipeWire stream only represents, whether the
respective PipeWire context is connected to PipeWire.
In addition to that, it may be the case, that the stream consumer just
recreates the stream.
So even if mutter would be able to know, when the stream consumer
destroyed a stream, but not the whole screencast or remote-desktop
session, then mutter would not know, whether the stream will be resumed
eventually or not.
So, add an explicit API call to the screencast interface to stop a
stream.
For virtual streams, this also means, that the respective virtual
monitor is destroyed.

Remote desktop version 2 added a new method ConnectToEIS .
ConnectToEIS allows clients to requests a file descriptor from the
compositor which can then be used directly from libei.
Once established, the communication between compositor and application
is direct, without the need to go through the portal process(es).

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.

This API aims to provide a way for users to capture input devices under
certain conditions, for example when a pointer crosses a specified
barrier.
So far only part of the API is implemented, specifially the session
management as well as zone advertisement, where a zone refers to a
region in the compositor which edges will eventually be made available
for barrier placement.
So far the remote access handle is created while the session is enable,
despite the input capturing isn't actually active yet. This will change
in the future once it can actually become active.

Xwayland got support for v4 in 23.1.0, thus let's reenable modifiers on
AMD.

The service channel D-Bus interface aims to be a "back door" for
services that needs special casing in Mutter, e.g. have custom private
protocols only meant to be used by that particular service.
There are currently no special casing implemented; only the basic
service channel infrastructure is added. There is a single method on the
interface, that is meant to eventually be used by
xdg-desktop-portal-gnome to open a Wayland connection with a private
protocol needed for the portal backend's rather special window
management needs.
The service channel Wayland client works by allowing one instance of
each "type", where each time needs to be defined to work in parallel. If
a new service client connects, the old one will be disconnected.
MetaWaylandClient's are used to manage the service clients, and are
assigned the service client type.
