Since Clutter's backend relies on MetaBackend now, initialzation has
to go through meta_init(), both in mutter and in gnome-shell.
However the compositor enum and backend gtype used to enforce the
environment used for tests are private, so instead expose a test
initialization function that can be used from both mutter and
gnome-shell.

If an application provides its window icon via wmhints, then mutter
loads the pixmap specified by the application into a cairo xlib surface. When
creating the surface it specifies the visual, indirectly, via an XRender
picture format.
This is suboptimal, since XRender picture formats don't have a way to specify
16bpp depth, which an application may be using.
In particular, applications are likely to use 16bpp depth pixmaps for their
icons, if the video card offers a 16bpp framebuffer/root window.
This commit drops the XRender middleman, and just tells cairo a visual to use
directly.

This reverts commit b95d7e8276e31a3414ec4d5ee13191c3f253fa1c.
It's poisoning cairo's GC cache with a GC that has the wrong
colordepth, leading to a crash in unrelated code later on.

This currently uses a hack where it pushes a CoglFramebuffer backed by a
texture to the framebuffer stack, then calls clutter_actor_paint() on
the window actor causing it to render into the framebuffer. This has the
effect that all subsurfaces of a window will be drawn as part of the
window.

We are really more interested in when a window is damaged, rather than
when it's painted, for screen casting windows. This also has the benefit
of not listening on the "paint" signal of the actor, meaning it'll open
doors for hacks currently necessary for taking a screenshot of a window
consisting of multiple surfaces.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/752
Make it possible to listen for damage on a window actor. For X11, the
signal is emitted when damage is reported; for Wayland, it is emitted
when any of the surfaces associated with the window is damaged.

Flatten the subsurface actor tree, making all surface actors children
of the window actor.
Save the subsurface state in a GNode tree in MetaWaylandSurface, where
each surface holds two nodes, one branch, which can be the tree root
or be attached to a parent surfaces branch, and a leaf, which is
used to save the position relative to child branch nodes.
Each time a surface is added or reordered in the tree, unparent all
surface actors from the window actor, traverse all leaves of the
tree and readd the corresponding surface actors back to the window
actor.

This object can be generally triggered without a X11 display, so make sure
this is alright. For guard window checks, use our internal
meta_stack_tracker_is_guard_window() call, which is already no-x11 aware.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/730
We indirectly were relying on the MetaX11Stack for this. We strictly
need the _NET_CLIENT_LIST* property updates there, so move our own
internal synchronization to common code.
Fixes stacking changes of windows while there's no MetaX11Display.

The MetaShapedTexture created by MetaSurfaceActor used to
be a ClutterActor, which means destruction was taken care
by Clutter.
Now that it's a plain GObject, we need to manually clean it
up.
Cleanup the shaped texture on disposal.

The surface offset allows an application to move itself in relative
coordinates to its previous position. It is rather ill defined and
partly incompatible with other functionality, which is why we ignore
it generally.
For dnd-surfaces though, it is the de-facto standard for applications
to properly position the dnd-icon below the cursor. Therefore apply
the offset on actor sync by setting the feedback actor anchor.

Commit b12c92e20639 ("wayland: Add MetaWaylandSurface::geometry-changed signal")
Added a "geometry-changed" signal on MetaWaylandSurface, but the matching
changes to src/wayland/meta-pointer-confinement-wayland.c made it listen
for geometry-changed on the surface-actor instead of on the surface itself,
leading to errors like these:
gnome-shell[37805]: ../gobject/gsignal.c:2429: signal 'geometry-changed' is invalid for instance '0x5653aa7cfe50' of type 'MetaSurfaceActorWayland'
This commit fixes this.

And add the necessary glue so those initialize a X11 clutter backend.
This should get Clutter tests that are dependent on windowing to work
again, thus they were enabled back again.

The end goal is to have all clutter backend code in src/backends. Input
is the larger chunk of it, which is now part of our specific
MutterClutterBackendNative, this extends to device manager, input devices,
tools and keymap.
This was supposed to be nice and incremental, but there's no sane way
to cut this through. As a result of the refactor, a number of private
Clutter functions are now exported for external backends to be possible.

After the introduction of locate-pointer (commit 851b7d063 -
“keybindings: Trigger locate-pointer on key modifier”), inhibiting
shortcuts would no longer forward the overlay key to the client.
Restore the code that was inadvertently removed so that inhibiting
shortcuts works on the overlay key again.

Geometry scale is applied to each surface individually, using
Clutter scales, and not only this breaks subsurfaces, it also
pollutes the toolkit and makes the actor tree slightly too
fragile. If GNOME Shell mistakenly tries to set the actor scale
of any of these surfaces, for example, various artifacts might
happen.
Move geometry scale handling to MetaWindowActor. It is applied
as a child transform operation, so that the Clutter-managed
scale properties are left untouched.
In the future where the entirety of the window is managed by a
ClutterContent itself, the geometry scale will be applied
directly into the transform matrix of MetaWindowActor. However,
doing that now would break the various ClutterClones used by
GNOME Shell, so the child transform is an acceptable compromise
during this transition.

meta_shaped_texture_update_area() is a private function that
is exposed in the public headers. It is not used anywhere
outside Mutter, and should really be in the private header.
Move it to the private header.

Now that MetaShapedTexture is not a ClutterActor anymore, it does
not make sense to make it a MetaCullable semi-implementation. This
is, naturally, a responsibility of MetaSurfaceActor, since now
MetaShapedTexture is a ClutterContent and as such, it only cares
about what to draw.
Move the MetaCullable implementation of MetaShapedTexture to
MetaSurfaceActor.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/409
By implementing ClutterContent, it is expected that
MetaShapedTexture can draw on any actor. However,
right now this is not possible, since it assumes
that the drawing coordinates and sizes of the actor
are synchronized with its own reported width and
height.
It mistakenly draws, for example, when setting an
actor's content to it. There is no way to trigger
this wrong behavior right now, but it will become
a problem in the future where we can collect the
paint nodes of MetaShapedTexture as part of other
ClutterContent implementations.
Use the allocation box passed by the actor to draw
the pipelines of MetaShapedTexture.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/409
Now that MetaShapedTexture is a ClutterContent implemetation that
is aware of its own buffer scale, it is possible to simplify the
event translation routines.
Set the geometry scale in MetaSurfaceActor, and stop adjusting the
surface scale when translating points. Also remove the now obsoleted
meta_wayland_actor_surface_calculate_scale() function.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/409
MetaWindowActor is the compositor-side representative of a
MetaWindow. Specifically it represents the geometry of the
window under Clutter scene graph. MetaWindowActors are backed
by MetaSurfaceActors, that represent the windowing system's
surfaces themselves. Naturally, these surfaces have textures
with the pixel content of the clients associated with them.
These textures are represented by MetaShapedTexture.
MetaShapedTextures are currently implemented as ClutterActor
subclasses that override the paint function to paint the
textures it holds.
Conceptually, however, Clutter has an abstraction layer for
contents of actors: ClutterContent. Which MetaShapedTexture
fits nicely, in fact.
Make MetaShapedTexture a ClutterContent implementation. This
forces a few changes in the stack:
* MetaShapedTexture now handles buffer scale.
* We now paint into ClutterPaintNode instead of the direct
framebuffer.
* Various pieces of Wayland code now use MetaSurfaceActor
instead of MetaShapedTexture.
* MetaSurfaceActorWayland doesn't override size negotiation
vfuncs anymore

With the addition of xauth support (commit a8984a81c), Xwayland would
rely only on the provided cookies for authentication.
As a result, running an Xclient from another VT (hence without the
XAUTHORITY environment variable set) would result in an access denied.
The same on X11 is granted because the local user is automatically
granted access to Xserver by the startup scripts.
Add the local user to xhost at startup on Xwayland so that the user can
still run a client by setting the DISPLAY as long as it's the same user
on the same host.

Introduce MetaCompositorX11, dealing with being a X11 compositor, and

When double clicking to un-maximize an X11 window under Wayland, there
is a race between X11 and Wayland protocols and the X11 XConfigureWindow
may be processed by Xwayland before the button press event is forwarded
via the Wayland protocol.
As a result, the second click may reach another X11 window placed right
underneath in the X11 stack.
Make sure we do not forward the button press event to Wayland if it was
handled by the frame UI.
