If an actor sets flag `CLUTTER_ACTOR_NO_LAYOUT` then that means it
is (or should be) unaffected by `queue_relayout` calls in its children.
So we can avoid propagating `queue_relayout` all the way up to the stage
and avoid a full stage relayout each time.
But those children whose parent has `CLUTTER_ACTOR_NO_LAYOUT` still need
to be allocated at some point. So we do it at the same point where it
happened before. Only we now queue a *shallow* relayout so the `allocate`
run on the next frame doesn't need to descend the whole actor tree anymore.
Only a subtree and hopefully very small.
For free-floating and top-level actors this provides a measurable
performance benefit. According to Google Profiler, calls to
`_clutter_stage_maybe_relayout` are now so cheap that they no longer show
up in performance profiles.

The meta_seat_native_constrain_pointer() function receives the current
pointer position, and the new pointer position as in/out parameters.
We were however calculating the new coordinates based on the last pointer
position if there was no pointer constrain in place.
Fortunately to us, this didn't use to happen often/ever, as a pointer
constrain function is set on MetaBackend initialization. This behavior
did also exist previously in MetaDeviceManagerNative.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/1028
The backend being initialized triggers a pointer warp (and motion event)
where we want to observe the callbacks put in place. So ensure we set
up the hooks before that could happen.

Just go ATM through backend checks, and looking up directly the
native event data, pretty much like the rest of the places do that...
Eventually would be nice to have this information in ClutterEvent,
but let's not have it clutter the MetaBackend class.

This is unlikely to happen, and unlikely to be right (eg. we don't translate
input event coordinates, since those are not in display coordinate space, we
don't offer any feedback for those either).
This can simply be dropped, we listen to XIAllMasterDevices, which suffices
for what we want to do.

When a Wayland window is mapped or unmapped, the Wayland compositor is
expected to send the coorespoindign `wl_pointer` enter/leave events to
the affected clients.
To do so, mutter calls `meta_wayland_compositor_repick()` which
eventually calls `meta_wayland_pointer_repick()` and
`repick_for_event()`.
If pointer input device has not been updated yet, the old clutter actor
is picked and no enter/leave event is emitted.
Make sure we update the pointer input device prior to do the repick to
get the actual `ClutterActor` under the pointer.
Closes: https://gitlab.gnome.org/GNOME/mutter/issues/1016https://gitlab.gnome.org/GNOME/mutter/merge_requests/1026
The private function `_clutter_input_device_update()` is not currently
exported.
This function calls `_clutter_input_device_set_actor()` which updates
the `ClutterActor` under the pointer, so making that function available
outside of Clutter will allow to make sure the pointer device actor is
updated prior to do picking.
Also, now that the functions is exported to the upper layers, drop the
underscore suffix from the function name.

As we now call `meta_wayland_compositor_repick()` when the effects are
complete for Wayland surfaces, we can safely remove the Wayland specific
code to do the same from `meta_window_show()`.

When mapping/unmapping windows, an animation may be played which can
change the actual actor size and location, hence defeating picking if
done too early.
Make sure we repick when the affects are completed, once the actor is
sized and placed.

When building the frame mask, the current reported frame size may not
match when is actually on screen if the buffer has not been updated
yet.
So instead of getting the frame size from the meta window, deduce it
from the texture size.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/1009
Currently, `meta_frame_get_mask()` and `meta_ui_frame_get_mask()` will
return the frame mask applied to the current frame size, by querying the
frame themselves.
To be able to get the frame mask at an arbitrary size, change the API to
take a rectangle representing the size at which the frame mask should be
rendered.

With Xwayland, the shape region is recomputed and reapplied even when
the actor is frozen to prevent the black shadows effect.
However, while recomputing the shape region, the current client size is
taken into account, rather than the size when the client was frozen,
which is ahead of the actual client size using the NET_WM_SYNC protocol.
Keep the current client area and to reuse them when the X11 window actor
is frozen for rebuilding the client mask texture.

Right now the CONTENT_SIZE request mode for a ClutterActor is only
respected by `clutter_actor_get_preferred_size()`, but not by
`get_preferred_width()` and `get_preferred_height()`. Those simply try
to ask the layout manager and will return [0, 0] for actors without
children. So be consistent and also return the content size in those two
functions.

In XDND, we just get a hint on XdndPosition about what's the action
chosen by the user. Make the data source actions the full set on
XdndEnter (as we can't know better), and pass the hint in XdndPosition
as the user chosen action as it should be.
Makes Wayland drop sites aware of the user action as per XDND with X11
drag sources, and still makes modifiers during DnD work.

The gamma value pointers of the current_state are overwritten by the
calls to memdup causing a small leak. while the leak itself is small, it
can be triggered quite often from things like night light.
