Monitor tile info is possible to fetch when RANDR version 15 is exposed
by the X11 server. We had inverted the check meaning that only if older
versions were advertised would we attempt to init the tile information.
Fix this guard, thus fix monitor tiling on X11.
Closes: https://gitlab.gnome.org/GNOME/mutter/-/issues/1524
Not calling libinput dispatch in the backend constructor defeats the
logic in post init as the device added events have not been processed
yet.
So instead of trying to guess the cursor initial visibility, simply
update it along when devices get added.
Additional benefit, we do not need to walk the all device list looking
for touchscreens anymore, we just need to check the device being added
since the current logic is to hide the cursor as soon as a touchscreen
is found.

At startup, libinput dispatch is called from the MetaSeatNative
constructed callback.
That means that we may get libinput events even before the default seat
is set.
In turn, processing those events may trigger the use the default seat
while it's still not set yet, and cause a crash of gnome-shell/mutter
at startup.
A simple reproducer for this is to start gnome-shell/mutter with a
tablet connected and the stylus in proximity, the proximity event will
cause gnome-shell/mutter to crash at startup.
To avoid that issue, avoid dispatching libinput events early from the
MetaSeatNative constructed callback, those events will eventually get
processed when the seat and the backend are all setup.

Commit 8bdd2aa7 would offset the window position by the difference
between the configured window size and the committed size from the
client to prevent the window from drifting while resizing.
This, however, did not take into account the actual geometry scale, so
when using any scale greater than 1, the window would rapidly drift away
due to that offset.
In order to solve this, we need to make sure we store away the pending
window configuration in the stage coordinate space, in order to not
loose precision. When we then calculate the offset given the result from
the client, it'll use the right scalars, while before, one scalar was in
surface coordinates, while the other in stage coordinates.

We want the bounding box so `ceilf` seems more appropriate. It was
only written using `roundf` before as a workaround for inaccuracies
coming out of `clutter_actor_get_transformed_size` that would have
tricked `ceilf` into landing on the wrong integer. But that's since
been fixed by 67cc60cbda so we can use `ceilf` now.

Because clones may not have identical geometry to their source actors.
So we can't use the geometry of the source actor to decide to take the
more optimized (more clipped) path.
Fixes: https://gitlab.gnome.org/GNOME/mutter/-/issues/1480
The "paint" signal of ClutterActor is deprecated and will be removed. We
have a good replacement to get notified about stage paints nowadays,
that is "after-paint" on ClutterStage, so switch to that signal where it
makes sense.
I didn't bother to update the few tests (namely Clutters
conform/texture-fbo.c, conform/text-cache.c,
interactive/test-cogl-multitexture.c and Cogls
conform/test-multitexture.c, conform/test-texture-mipmaps.c) where it's
harder to replace the signal since we don't build those anyway.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1522
The paint-wrapper test wraps around the painting process of an actor to
paint its own texture before and after painting, it does that using the
"paint" signal.
This signal is deprecated and will be removed from Clutter, and since
this "use-case" won't be supported anymore afterwards (the proper way is
to use a ClutterEffect for things like this), remove the test.

Rely on the seat stage, or other ways to fetch it. Also rely that
there is actually a single stage, so that we assign the right stage
to all events going out of the seat, in a single place.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1486
This is a bit scattered around, with the setter/getter in Clutter, and
it only being only directly honored in Wayland (it goes straight through
device properties in X11).
Make this private native API, and out of public ClutterInputDevice API.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1486
Make the upper part agnostic about the device being relative in order
to avoid applying keep-aspect. The X11 bits already are, so make it
sure it's also the case for the native backend.

The semantics for libinput events are not as expected here. Besides
it's pointless, as those should arrive per-slot in a burst, and we
cancel on the first event.
We can simply use the Clutter event for this.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1486
As it does seem from a read to libinput code, TOUCH_CANCEL events
actually do contain slot information, and are emitted per-slot.
This means we can avoid iterating over the slots ourselves, they
are still expected to be sent altogether.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1486
We want to coalesce multiple touch events into the same wl_touch.frame
event. Instead of poking internals to peek the touch events (and their
slots) coming at us before we handle them, simplify things by queueing
the event at a slightly lower priority than events, so we are ensured
to handle all pending input events before sending the event.
If there's no pending events, we can just send the frame event. As it
doesn't make sense to hold any longer.

When malformed modes are provided and no valid mode spec is found, mutter
will eventually try to access the last element of an empty list. Warn about
this and exit properly.

We will use a dedicated variable when transitioning to/from fullscreen state
and leave the previously used 'saved_rect' exclusively for transitioning
between floating and maximized state.

Implements the "prior window window geometry dimensions" as described in
the documentation of 'xdg_toplevel' request 'unset_maximized':
"If available and applicable, the compositor will include the window
geometry dimensions the window had prior to being maximized in the
configure event."
and 'unset_fullscreen':
"The compositor may include the previous window geometry dimensions in
the configure event, if applicable."
Fixes https://gitlab.gnome.org/GNOME/mutter/issues/792.
If this call is available, we can turn libX11 IO errors (fatal by definition)
into something we can recover from. Try to dispose all X11 resources and close
the display instead, so the compositor can survive the event.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1447
If the MetaX11Display abruptly closed when X11 windows were present,
we would still try to deal with them while freezing/thawing for the
"fade out" animation.
At the bottom of that, the X server may be gone, just try to cope
with it.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1447
We're going to enforce some invariants a bit stricter and will only
allow allocating if an actor is mapped, not only visible.
Since actors are only mapped if their parent is mapped and stages are
hidden by default, we need to show the stage to ensure the actors are
mapped before we allocate them. So do that and call clutter_actor_show()
on the stage before fake-allocating the test actors.
