The shell might raise and make windows recent for another workspace when
an app gets activated on another workspace. Making the windows only
recent on the current workspace thus results in inconsistent focus when
another window of the same app is closed.

There are existing extensions that implement desktop icons as
a combination of a GTK program and a small extension to make
the wayland window behave as if it was of type DESKTOP on X11.
That's quite painful, as it requires reimplementing WM behavior
that is already implemented in mutter itself (stacking, stickiness,
skip-taskbar, ...), as well as modifying gnome-shell to consider
the window in addition to "real" DESKTOP windows (workspace-switch
animations, ctrl-alt-tab, ...).
In addition to that, other extensions may also have special handling
of DESKTOP windows, and their code cannot easily be monkey-patched
to handle "alternative" desktop icons.
This whole game of whack-a-mole can easily be avoided by allowing
desktop-icons extensions to mark their desktop windows as DESKTOP,
so do just that.

It's the 10 bit equivalent to NV12 and uses the same layout as P016, i.e.
16 bit components with the lowest 6 bits set to 0 (padding), allowing us
to use 16 bit "subformats".
Thus adding support is quite trivial as we can reuse the NV12 shader.
The format is widely supported in decoding and display hardware (on Intel
since Kaby Lake), as well as modern codecs (AV1, VP9, HEVC) and has
visible quality advantages over NV12.
Note that the additional colors are lost if composited to a 8 bit RGB
framebuffer. Switching between direct scanout and compositing can thus
cause quality differences. This is no new phenomena, however, as the
same is the case already for e.g. GL clients using 10 bit formats -
including video players.
Also note that P012 and P016 could trivially added as well - it's not
done here as they are uncommen and thus hard to test.

We can change power save mode for two reasons: gsd-power told us to, or
we saw a hotplug event. Sometimes it's useful to be able to make the
distinction to why a power save mode changed, so add a reason to the
signal.

This is meant for compatibility purposes with the shell extensions
avoiding to break a bunch of them in the last minute and we would
drop it in the GNOME 46 release.

These "features" are somewhat less featured, it's becoming too ugly
to handle all of them with a single API call. The clear outlier are
buttons, so move them to a separate function.

To be able to later support more complex YUV formats, we need to make
sure that MetaShapedTexture (the one who will actually render the
texture) can use the MetaMultiTexture class.

In future commits, we want to be able to handle more complex textures,
such as video frames which are encoded in a YUV-pixel format and have
multiple planes (which each map to a separate texture).
To accomplish this, we introduce a new object `MetaMultiTexture`: this
object can deal with more complex formats by handling multiple
`CoglTexture`s.
It supports shaders for pixel format conversion from YUV to RGBA, as
well as blending. While custom bleding is currently only required for
YUV formats, we also implement it for RGB ones. This allows us to
simplify code in other places and will be needed in the future once
we want to support blending between different color spaces.

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.

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.

Commit 7e9d9c7eb9 added new API to replace GTK for accelerator
parsing.
Unfortunately there is another case in gnome-shell, where we have
to get the label from the logical binding name rather than the
modifier+keysym combination.
Add another small method to cover that use case.

After !2489, the active workspace's MRU list is now used to pick
the next focus window instead of the stack order.
This list is currently only updated on focus, which can lead to
surprising behavior when closing a window after activating its
ShellApp in the shell.
That is because raising a window (as part of shell_app_activate())
will only change the stacking order, so when closing the active
app window, the focus will switch to whatever had focus before the
app was activated, not the app's next window.
In order to allow gnome-shell to address this, add a new
raise_and_make_recent() method that also adjust the MRU order.

This API will be used by GNOME Shell to handle X11 events
in the relevant places, as a substitute to gdk_window_add_filter().
It is ATM still a bit ironic, since the Mutter X11 event handler
is itself a GdkFilterFunc, but it may move away from that eventually.

This is a public API change. Add device/sequence parameters to this
operation, so that window dragging and resizing can stick to one
