Since we schedule frames for each stage view seperately now, surfaces receive
frame callbacks for each stage view they are visible on.
Only emit frame callbacks for the primary stage view.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1468>
Our main use case of `is_obscured()` is frame callback emission.
Since we now support stage views running at differt speeds, we
need to know whether an actor is visible on a specific stage view
in order to schedule frame callbacks accordingly.

Commit e28c1ab4 added a hints_have_changed() function to only
recalculate windows features when the WM_NORMAL_HINTS change.
That function hints_have_changed() however was merely checking whether
the various XSizeHints flags where flipped, which is not sufficient
because the hints may remain the same while the actual values are
changed.
Not checking for the actual value differences would prevent some windows
from being able to switch fullscreen.
Improve the helper function hints_have_changed() to check not only for
flags being flipped, but also for the values being changed for each
relevant XSizeHints flags being set currently.

Sometimes the automatically selected primary GPU isn't suitable with no
way to make an well educated guess to do it better. To make it possible
for the user to override the automatically calculated default, make it
possible to override it using a udev rule.
E.g. to select /dev/dri/card1 as the primary GPU, add a file e.g.
/usr/lib/udev/rules.d/61-mutter-primary-gpu.rules (path my vary
depending on distribution) containing the fellowing line:
ENV{DEVNAME}=="/dev/dri/card1", TAG+="mutter-device-preferred-primary"
Reboot or manual triggering of udev rules to make it take effect may be
required.

Instead of aborting with an error, display a half transparent gray
square instead of cursors and log a warning in the journal, allowing the
user to fix their system withotu having to rely on switching to a TTY.
It will be immediately obvious the cursor is silly looking, which will
be a better hint than just aborting.

It'd happen that the test runner would get CPU starved, and not see the
frame-clock changed notification before the timeline stopped. Decrease
the risk for this by moving the initial position of the actor having its
position transitioned to be closer to the view edge. This means the
frame clock will be changed earlier, increasing the chance of the
timeline not stopping before the relayout happens.

For X11 grabs, the pattern matching mechanism would simply ignore
applications which have neither WM_CLASS nor WM_NAME set.
When dealing with an override redirect window however, it is not
uncommon that these window have neither value set as these window are
supposed to be ignored by the window manager.
When the WM_CLASS or the WM_NAME is not set by the client, assume the
value is empty so the pattern matching can allow for these.

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.

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.

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.

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.
