6ecd911dd0 backend: Take over seat ownership from the clutter backend
Having the clutter backend owning and managing creates complication for
implementing graceful shutdown, so move it to the real backend.

42d614f6fa backend-native: Add non-functional 'headless' mode
Make it possible to pass --headless as a command line argument in order
to turn the native backend "headless". This currently doesn't do
anything, but the intention is that it should not use logind nor KMS,
and work completely headless with only virtual outputs.

d6f720497a backends: Move HW cursor inhibitors to MetaBackend
We are aiming for a split of HW and SW cursor rendering management.
Given the HW plane is a limited resource and the amount of cursor
renderers may be >1 (due to tablets, even though we currently use an
always-software cursor renderer there), it would ideally be able to
switch between renderers.

Being MetaCursorRenderer not really a singleton, having cursor
inhibitor accounting here doesn't pan out. Make it MetaBackend API
so all cursor renderers get the same picture.

6db7d8f830 backend: Add a backend release function
Mutter still relies heavily on singletons such as its MetaBackend.

For that, the backend implementation has a meta_init_backend() function
which is called at startup from meta_init(), which creates the desired
backend and sets the singleton which is returned by meta_get_backend().

Unfortunately, that means that the backend is never actually freed, and
all the code from the backend finalize function never actually get
called.

Add a meta_release_backend() to free the backend singleton.

1571f8078a Reshuffle Wayland initailization
Move Wayland support (i.e. the MetaWaylandCompositor object) made to be
part of the backend. This is due to the fact that it is needed by the
backend initialization, e.g. the Wayland EGLDisplay server support.

The backend is changed to be more involved in Wayland and clutter
initialization, so that the parts needed for clutter initialization
happens before clutter itself initialization happens, and the rest
happens after. This simplifies the setup a bit, as clutter and Wayland
init now happens as part of the backend initialization.

1f00aba92c backends: Add MetaInputDevice derivable class
This class sits between ClutterInputDevice and the backend implementations,
it will be the despositary of features we need across both backends, but
don't need to offer through Clutter's API.

As a first thing to have there, add a getter for a WacomDevice. This is
something scattered across and somewhat inconsistent (eg. different places
of the code create wacom devices for different device types). Just make it
here for all devices, so users can pick.

e02fef8e2f meta: Hide libmutter symbols by default and selectively export them
Make meson link libmutter using -fvisibility=hidden, and introduce META_EXPORT
and META_EXPORT_TEST defines to mark a symbols as visible.
The TEST version is meant to be used to flag symbols that are only used
internally by mutter tests, but that should not be considered public API.

This allows us to be more precise in selecting what is exported and what is
not, without the need of a version-script file that would be more complicated
to maintain.

97f2c7c161 Add remote desktop and screen cast functionality
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.

Instead of using a environment variable, add a new 'experimental

The D-Bus API is disabled when the experimental feature is not enabled,

response. A new property 'IsExperimentalApiEnabled' is added to let the
D-Bus client know whether it is possible to use the experimental API or

8163ca6821 Add support for scaled logical monitor framebuffers
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).
