Syncronized subsurfaces that call into `merge_pending_state` might
otherwise not create new destroy handlers, ending up with a invalid
handler ids, throwing errors and leaking.

As we will start adding support for more pixel formats, we will need to
define a notion of planes. This commit doesn't make any functional
change, but starts adding the idea of pixel formats and how they (at
this point only theoretically) can have multple planes.
Since a lot of code in Mutter assumes we only get to deal with single
plane pixel formats, this commit also adds assertions and if-checks to
make sure we don't accidentally try something that doesn't make sense.

We were just looking at DnD actions which might still be unset at that
point. Instead of doing these heuristics, store the selection type on
the data offer.
Fixes: https://gitlab.gnome.org/GNOME/mutter/issues/845
Requesting a selection with a NULL data source means "unset the clipboard",
but internally we use an unset clipboard as the indication that the
clipboard manager should take over.
Moreover, this unset request may go unheard if the current owner is someone
else than the MetaWaylandDataDevice.
Instead, set a dummy data source with no mimetypes nor data, this both
prevents the clipboard manager from taking over and ensures the selection
is replaced with it.
The MetaSelectionSourceMemory was also added some checks to allow for this
dummy mode.
Fixes: https://gitlab.gnome.org/GNOME/mutter/issues/793
Instead of taking resource and send/cancel funcs, take a
MetaWaylandDataSource, which exposes all the vfuncs to do the same on the
internal resource.
This has the added side effect that only MetaWaylandDataSource has a
pointer to the wl_resource, which may be unset untimely.
Fixes: https://gitlab.gnome.org/GNOME/mutter/issues/842
If a data source is destroyed we first unset the resource, and then try to
unref the related selection source. At this point the only event that might
be emitted by the internal selection machinery is .cancelled, so make sure
we avoid it on destroyed sources.
Fixes: https://gitlab.gnome.org/GNOME/mutter/issues/842
We are still poking the mimetypes from the previous selection when creating
the new offer. This may come out wrong between changes of the copied
mimetypes.

A frame callback without damage is still expected to be responded to.
Implement this by simply queuing damage if there are any frame callbacks
requested and there is no damage yet. If there already is damage,
we'll be queued already, but with more correct damage. Without we simply
need to make sure we flush the callbacks if any area of surface is not
occluded.
Fixes: https://gitlab.gnome.org/GNOME/mutter/issues/457https://gitlab.gnome.org/GNOME/mutter/merge_requests/839
For the most part, a MetaWindow is expected to live roughly as long as
the associated wl_surface, give or take asynchronous API discrepancies.
The exception to this rule is handling of reparenting when decorating or
undecorating a window, when a MetaWindow on X11 is made to survive the
unmap/map cycle. The fact that this didn't hold on Wayland caused
various issues, such as a feedback loop where the X11 window kept being
remapped. By making the MetaWindow lifetime for Xwayland windows being
the same as they are on plain X11, we remove the different semantics
here, which seem to lower the risk of hitting the race condition causing
the feedback loop mentioned above.
What this commit do is separate MetaWindow lifetime handling between
native Wayland windows and Xwayland windows. Wayland windows are handled
just as they were, i.e. unmanaged together as part of the wl_surface
destruction; while during the Xwayland wl_surface destruction, the
MetaWindow <-> MetaWaylandSurface association is simply broken.

Dropping the grab has the side effect that the pointer will be re-picked,
and it might find another surface with a pointer constraint. If that were
the case, the focus change would try to add the pointer constraint before
the now old focus surface released its own.
Just invert these operations, so the constraint is unset before the repick
that might enable another pointer constraint.
Closes: https://gitlab.gnome.org/GNOME/mutter/issues/779
Just like sync_focus_surface() does, we shouldn't set a focus surface while
the pointer is hidden, so the illusion that there is none remains.
Closes: https://gitlab.gnome.org/GNOME/mutter/issues/779
After commit 75cffd0e ("shaped-texture: Implement ClutterContent"), the
input to the meta_wayland_tablet_tool_get_relative_coordinates function
is already scaled correctly. By scaling it again, all stylus events are
getting mapped to the screen incorrectly (for anything != 100% scaling).

Correct silly mistake where the MetaWaylandSurface was passed as the
user_data of the surface actor destroy signal handler, instead of the
expected MetaWaylandActorSurface.
Fixes: https://gitlab.gnome.org/GNOME/mutter/issues/844
Since the recent clutter-content work, legacy scaling (in contrast
to the new stage-view-scaling) only applies to surfaces that belong
to a window. This broke scaling of DnD surfaces.
As a workaround, apply the same scaling on DnD-surface-actors until
we use stage-view-scaling by default and can remove this again.
Also: small corrections of geometry calculation
https://gitlab.gnome.org/GNOME/mutter/merge_requests/780
This allows us to implement more sophisticated logic for the different
cases. For DnD surfaces, use the geometry scale of the monitor where
the pointer is, instead of incorrectly assuming '1' as it was before.

Some drivers expose EGL_EXT_image_dma_buf_import_modifiers so you can
query supported formats, but don't support any modifiers. Handle this by
treating it like DRM_FORMAT_MOD_INVALID.

When using xdg-output v3 or later, the Wayland compositor does not send
xdg_output.done events which are deprecated.
Instead, it should send a wl_output.done event for the matching
wl_output.

When starting a DnD operation, mutter would remove keyboard focus from
the client, only to restore it on the data offer destroy.
However, if the DnD fail, the keyboard focus is not restored, leaving
the user unable to type in the focused window, even after clicking in
the window.
That issue would show only on first attempt, as further DnD attempts
would destroy the previous data offer which would also restore the
keyboard focus.
Make sure we restore the keyboard focus on drag end as well.
https://gitlab.gnome.org/GNOME/mutter/issues/747
On drag start, `data_device_start_drag()` issues a keyboard grab, which
in turn will unset the current input focus.
There is not need to unset the input focus in `data_device_start_drag()`
as this is redone in `meta_wayland_keyboard_start_grab()`
https://gitlab.gnome.org/GNOME/mutter/issues/747
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.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/664
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 b12c92e206 ("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.

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.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/672
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.
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.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/735
There may be cases where a X11 client does not spawn any X11 windows (eg.
simple clients like xinput --list, or xlsclients), in this case the Xwayland
server would remain running until X11 windows happen to come and go in the
future.
Firing the shutdown timeout on restart caters for this, and would be undone
if the client maps X11 windows.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/728
Where the prepare_auth_file() call is, it does create a new one on every
respawn of Xwayland. This is not benefitial, as the XAUTHORITY envvar is
already fixed in the session.
Only create the XAuthority file once, and reuse it on future Xwayland
respawns.
