It's the impl side that wants to add impl side idle sources, or fd
sources, etc, so make it part of MetaThreadImpl.
This changes things to be GAsyncQueue based. While things are still
technically single threaded, the GAsyncQueue type is used as later we'll
introduce queuing tasks asynchronously, then eventually queuing across
thread barriers.

It currently does exactly what MetaKms and MetaKmsImpl did regarding the
context separation, which is to isolate what may eventually run on a KMS
thread into a separate unit. It works somewhat like a "user thread",
i.e. not a real thread, but will eventually learn how to spawn a
"kernel thread", but provide the same API from the outside.

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).

Accessibility should be handled on the receiving end, if needed. Make
sure this is the case by listening on some signals, verifying they are
only triggered if we're not capturing input.

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.

When a relative pointer motion gets constrained (e.g. a monitor edge or
barrier), save the constrained relative motion delta too.
This will later be used to send the remaining motion delta to input
capture clients.

An input only grab is a ClutterGrab on the stage that doesn't have an
explicit actor associated with it. This is useful for cases where event
should be captured as if focus was stolen to some mysterious place that
doesn't have anything in the scene graph that represents it.
Internally, it's implemented using a 0x0 sized actor attached directly
to the stage, and a clutter action that consumes the events. An
input-only grab takes a handler, user data and a destroy function for
the user data. These are handed to the ClutterAction, which handles the
actual event handling.

Adding a barrier and later enabling the input capture session will
create MetaBarrier instances for each added input capture barrier.
The barriers are created as "sticky" which means that when a pointer
hits the barrier, it'll stick to the point of entry, until it's
released.
The input capture session is also turned into a state machine with
explicit state, to more easily track things.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2628>
This allows for a sticky barrier to hold the pointer until it is
released, but the owner of the barrier doesn't need a barrier event to
release it. It will be used to implement input capturing.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2628>
A sticky barrier means that a pointer in motion intersecting a barrier
doesn't move once having hit it. The intention with this is to allow an
input capture clients to continue a motion once a barrier is hit.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2628>
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.
v2: Remove absolute/relative pointer, keep only pointer (ofourdan)

A 2D actorless paint volume can't ever need `enlarge_for_effects` because
it has no depth. Clamping to the pixel boundary is sufficient in this case
and avoids extending volumes on the edge of the view into the next view.
Which then avoids unnecessary secondary monitor updates.
Paint volumes correctly become actorless where `clutter_actor_finish_layout`
calls `_clutter_paint_volume_transform_relative`.

This was a temporary fix until there was a better crossing event
delivery mechanism that accounted for actor changes beneath the pointer.
We nowadays have that, and don't seem to need this extra kick to get
crossing events triggered (and cursor changes, etc) when windows appear
or disappear under the pointer.
This commit is effectively a revert of commit
a64dba4d7a.

With window_is_terminal gone, "strict" and "smart" focus mode have no
behavioural difference. Let's broaden the scope of strict focus mode,
such that windows never automatically focus unless they are an ancestor
to the transient.

As noted in the comments of window_is_terminal, this is a hack. This
code has not been touched for the better part of a decade. App res_class
tends to differ between Wayland and X11, so it is likely that none of
these apps have been recognised as terminals under Wayland ever. Also,
there are reports that strict focus mode also does not work under X11,
likely due to changes in these terminal apps over the years resulting
in different res_class than those manually specified in here. Let's remove
this hack and change strict focus mode accordingly.

Instead of using `clutter_actor_get_resource_scale()`, we now deduce the
intended buffer scale from the window by dividing the unscaled size by
the final actor size. This is more correct as while the return value of
`clutter_actor_get_resource_scale()` depends only on the monitor where
the surface resides, the actual scale of the surface is determined
solely by the application itself. `get_resource_scale` will differ from
the actual buffer scale if the application only supports 100% scaling
(Xwayland), or is performing scaling with wp_viewporter (clients using
fractional_scale_v1).
This also fixes a mismatch between the calculated buffer sizes between
`meta_window_actor_get_buffer_bounds` and
`meta_window_actor_blit_to_framebuffer` which causes broken
screencasting for Chromium 114 and later when using the native Ozone
Wayland backend.
Additionally, this commit also changes
`meta_window_actor_blit_to_framebuffer` from using a simple translation
to using an inverted matrix transformation of the transformation matrix
between the parent of the window actor and the surface actor to ensure
maximum sharpness for fractionally scaled windows.

Previously, restarting mutter in an X11 session resulted in
the previously set color temperature not being applied.
Fix that by applying the color temperature right after
the org.gnome.SettingsDaemon.Color proxy has been created.
Furthermore, only call `update_all_gamma()` from `on_gsd_color_ready()`
when the temperature has actually changed. Otherwise there is no need
since the current temperature has already been (or will soon be) applied
to all ready color devices.

We'd get a re-entry like scenario when destroying the PipeWire stream
object, where PipeWire would call the stream process vfunc. When this
happened, we had already destroyed the stream, so don't try to dequeue
or anything, just do an early exit. Fixes the following crash in the
test case client:
