This is no longer necessary to prevent the bits we wanted to be
prevented by the presence of this grab. We can drop this, and
let it work through the MetaWaylandPointerGrab interface.

The whole reason for META_GRAB_OP_WAYLAND_POPUP to exist is to
avoid windows from being activatable/movable/resizable when a
grabbing xdg_popup is active.
Use the meta_display_is_grabbed() method which can tell this
from existing MetaWaylandCompositor grabs, so that this remains
true after dropping META_GRAB_OP_WAYLAND_POPUP.

Make this public API check just return a boolean about whether
there is an existing grab, instead of exposing MetaGrabOp.
It is desirable to avoid exposing details like
META_GRAB_OP_WAYLAND_POPUP, so that MetaDisplay and wayland
grabs can port to ClutterGrab at their own pace, but also
this further information is unused.
This is likely to be temporary API anyways, after both
MetaDisplay and wayland grabs port to Clutter, it will be
possible to check the ClutterStage for all of them.

Rewrite this codepath so it handles the grab ops that it cares
about, and ignores the rest. This way the code works despite
possible future modifications to MetaGrabOp (e.g.
META_GRAB_OP_WAYLAND_POPUP removal).

This piece of event handling only applies on windows receiving events while
the display is ungrabbed (i.e. for raising it, or beginning a move/resize
operation).
Move the checks on the current grab operation outside of window.c and into
events.c, so all checks about the current grab operation move closer to the
main event handler.

Currently subschemas in org.gnome.mutter are marked as child schemas,
but subschemas in org.gnome.mutter.wayland are not. There's no harm
with that, it's just nice to be consistent, and having schemas show
up in `gsettings list-children` is a nice touch.

The GQueue node for transactions are inlined in the transaction struct,
meaning we should never let the GQueue API free the node itself, as that
actuall frees the transaction itself.
We did this during tear down if there were left-over transactions,
meaning we ended up with use-after-free issues after having popped
transactions from the queue.
Fix this by just popping the link itself, which won't attempt to free
it. It is effectively freed when freeing the transaction itself so we
won't leak any memory.

During grabs, it is expected that the X11 focus does not correspond
to the display's focus window, as focus should be on the stage's
XWindow instead.
This still messes up the keyboard focus even after we stopped moving
the X11 focus, because we end up with a presumed X11 focus window
of None, and as a result the stage is considered unfocused.

When the pointer crosses monitors, we account for a single motion event
resulting in the pointer moving across more than 2 monitors, in order
to correctly account each monitor scale and the distance traversed
across each monitor in the resulting relative motion vector.
However, memory on the direction is kept short, each iteration to
find the target view just remembers the direction it came from. This
brings a pathological case with 4 monitors with the same resolution
in a 2x2 grid, and a motion vector that crosses monitors at the
intersection of all 4 in a perfect diagonal. (Say, monitors are
all 1920x1080 and pointer moves from 1920,1080 to 1919,1079).
In that case, the intersection point at the crossing between 4
monitors (say, 1920,1080) will be considered to intersect with 2
edges of each view. Since there is always at least 2 directions to
try, the loop will always find the direction other than the one
it came from, and as a result endlessly jump across all 4 possible
choices.
In order to fix this, consider only the global v/h directions,
we already know if the pointer moves left/right or up/down, so
only consider those directions to jump across monitors.
For the case at hand, this will result in three monitors visited,
(either bottomright/bottomleft/topleft, or bottomright/topright/topleft)
with a total distance of 0,0 in the middle one, effectively
resulting in a correct diagonal motion.

Refactor code so that variables don't depend the on motion line
content, but the other way around. This makes it clearer what each
vector means.
This has no functional changes.

Some tests expect warnings to be logged, and handle that using
g_test_expect_message(). However, if debug topics are enabled, this
causes g_logv() to expect expected messages to also contain entries with
the debug level 'message' or higher to be listed in the expected message
list. Since meta_topic() always logged using g_message(), enabling debug
topics caused any test that used g_test_expect_message() and had debug
logging somewhere along the code path to fail.
Fix this by changing the log level of meta_topic() to 'debug' if we're
in a test. This doesn't mean they won't be visible, they still will
since debug log entries are printed by default during testing.

That means before-update, prepare-paint, before-paint, paint-view, after-paint,
after-update. While yet to be used, it will be used as a transient frame
book keeping object, to maintain object and state that is only valid
during a frame dispatch.

It was missing a cairo_region_t. This also needs adapting the test case,
since prior to this, we didn't actually bump the paint counter when
painting.
When a scanout test isn't waiting to go from compositing to scanout, but
from scanout to compositing, we should not early out when we actually
composited, since that's what we're expecting to see.

Fix a silly copy-paste mistake. Since `GObject` is the parent class,
chaining up to `dispose()` from within your `finalize()`
implementation just leads to a little memory leak and nothing worse.

We might end up with a NULL opaque_region here in some circumstances
(client deleted _NET_WM_OPAQUE_REGION, or passed invalid data or a
region with 0 rectangles), account for that when freeing the variable.

These frames client will use a visual with alpha information, and
report the opaque frame shapes through the _NET_WM_OPAQUE_REGION
window property. We can use this information in the Mutter side
for accurate opaque shapes, despite X11 windows with frames now
being seen as possibly transparent.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2758>
Since the windows created by the frames client will have a RGBA visual, we
no longer can perform simple tests about whether the window is opaque. For
that, we will need to additionally know whether the client-side window has
a visual with an alpha channel.

This does nothing wrt making race conditions shorter in the
X11 window manager switch case, but is a nice to have in order
to ensure an orderly shutdown of X11 stuff.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2796>
Restarting a X11 window manager is a busy process, trying to leniently
quit the main loop may result in old and new instances each having a
frames client up and running, and the window handover to be less clean
than it should due to the frames client that is about to exit still
being able to react to the batch of events resulting from the window
manager switch that is already undergoing.
In order to avoid extending this transition period any long, make
the frames client exit() the process immediately when SIGTERM is
gotten from the parent process.
