cc0ec14712 monitor-manager: Add new backlight D-Bus API
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.

0c2fa8e9a8 clutter/stage-view: Add linear intermediate color space buffer
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

c8c5560916 backends/native: Main thread rt-scheduler: experimental feature no more
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.

a2a4067e07 screencast: Add ability to stop streams
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.

2fb3bdf774 input-capture: Hook up capturing of events to active session
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

a8b013b006 Add beginning of input capture API
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.

74fcdb9a62 Introduce the 'service channel' D-Bus service
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.

9fab8410d7 data/udev: Don't disable KMS modifiers on newer i915 systems
When modifiers are enabled on mutter on some of the older i915 systems observed
Black-screen on 2nd monitor during multi-head use cases, upon debugging observed
that disabling modifiers on these systems resolved the Black-screen issue:!1618.

This issue depends whether we have enough DBuf space to provide required bandwidth
for the userspace demands. Those platforms which have less Display Buffer, will
just have more chance to face lack of it. However it still depends on various
factors like amount of planes(i.e the more planes we have, the more we divide the buffer),
refresh rate, bpp and so on.
This affects watermark calculations and the minimum blocks required for at least
wm level 0. If we don't have sufficient ddb at least for wm0 for all planes in
the configuration then it is rejected.

Until we have TEST_ONLY commit solution is built we could make sure to disable
modifiers support on these older i915 systems based on udev rules defined in this commit.

This commit makes sure that modifiers are still usable on latest i915 systems.

7a1beb817d backends: Expose InputMapping D-Bus path to determine tablet mapping
Currently, the peripheral "output" setting will be unset if Mutter is
deciding automatically the mapped output of a tablet device. In that
case, gnome-control-center will have a hard time figuring out itself
the better output to show the tablet calibration UI, unless it's hand
held by Mutter.

Add this private D-Bus interface so that gnome-control-center can look
up the output as determined by Mutter to bring the missing harmony
between both. This interface consists of a simple method to get the
mapped output for a input device node.

e2d4da8562 screen-cast-stream: Embed the wayland output name to streams
If a screencast session is screencasting from multiple monitors,
it is not possible to distinguish which stream (or PipeWire stream
node id) belongs to which connected monitor (such information may be useful
to the caller e.g. caller might want to embed the stream in a window
and name it after the monitor connector, for example). This change adds
optional metadata for monitor streams to also return the wayland output
name with the stream.

Ideally, this metadata should equip the caller to get more information about
display from the following Wayland interfaces:

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
