Certains keys (such as ~ and |) are in the keyboard map behind the
second shift level. This means in order for them to be input, the
shift key needs to be held down by the user.
The GNOME Shell on-screen keyboard presents these keys separately on
a page of keys that has no shift key. Instead, it relies on mutter
to set a shift latch before the key event is emitted. A shift latch
is a virtual press of the shift key that automatically gets released
after the next key press (in our case the ~ or | key).
The problem is using a shift latch doesn't work very well in the face
of key repeat. The latch is automatically released after the first
press, and subsequent repeats of that press no longer have shift
latched to them.
This commit fixes the problem by using a shift lock instead of a shift
latch. A shift lock is never implicitly released, so it remains
in place for the duration of key repeat.

The `guess_candidates()` function scores each display that an input
device could be mapped to and then uses the `sort_by_score()` comparator
to find the best option. The function expects the list to be sorted from
best to worst, but the comparator currently sorts them in the opposite
order. This causes the function to end up returning the _worst_ match
rather than the the best. This commit reverses the sort order of the
comparator so that the best display can be returned as intended.

This does two things to frown upon:
- Modifies ClutterEvent structs, while the effort is to have those
completely opaque, and readonly after creation from the input
thread side.
- Stores state in the ClutterInputDevice struct, event though those
are also considered static after creation, managed by the input
thread, etc.
Stop doing that. This makes all events just forwarded as-is in
the ClutterStage/clutter-main.c code.
Handling of click count sounds like material for a ClutterGestureAction
(or perhaps ClutterClickAction), all of both callers now do it in place
at the moment, while gestures lack a better state tracking and management.

This will not try the captured-event shenanigans to emulate grab
behavior, instead relying on event delivery being influenced by
other grab mechanisms.
While at it, improve handling of additional touchpoints by
cancelling the click action right away, as the differences in
event handling make this unwanted behavior surface.

By default, the pan action performs matrix translations on the
child widget. Nobody wants that (or, nobody wants *just* that).
It's cleaner not to mix mechanism and effect in ClutterGestureAction
subclasses, so drop this base implementation, and change the signal
accumulator so it's more similar to event signals (not that it's
used any longer, anyway).

Mutter already calculates and tracks the damage rectangles to redraw
only areas of the screen that change since the last time a buffer was
used.
This patch extends this by using the EGL_KHR_partial_update extension to
inform the GPU in advance that only those areas will be changed, which
may allow for further optimization.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2023>
Add support for a cogl function to set the damage_region on an onscreen
framebuffer.
The goal of this is to enable using the EGL_KHR_partial_update extension
which can potentially reduce memory bandwidth usage by some GPUs,
particularly on embedded GPUs that operate on a tiling rendering model.

Defining valid values makes
1. changing settings less error prone
2. sure they are discoverable.
This does reset the values once on update, but fortunately does *not*
change the way to set the values. Thus e.g. enabling fractional scaling
via terminal command still works as before and internet guides stay valid.

This will make clients immediately aware of the output disappearing,
while still allowing for a grace period of 10 seconds for attempting to
bind to it before it turning into a protocol error. This API added as
part of wayland 1.18.
This requires us to not add the output resource to the output resource
list, if the output was made inert. This effectively makes the resource
useless, but that is harmless, since shortly after, the client will
clean it up anyway.

This will be crucial when we start to remove the global directly when an
output is removed, as that means Xwayland might have removed the output
before we managed to get our queries in.

We setup Xwayland in an early phase of the X11 display, before we had a
MetaX11Display, and teared down in a couple of places happening when
tearing down the Xwayland integration if the X server died or
terminated. It was a bit hard to follow what happened and when it
happened. Attempt to clean this up a bit, with things being structured
as follows:
* Early during X11 display connection setup, only setup the rudimentary
X11 hooks, being the libX11 error callbacks, and adding the local
user to XHost.
* Move "initialize Xwayland component" code to a new
'x11-display-setup' signal handler. Things setup here are cleaned up
in the 'x11-display-closing' handler.
* Connect to 'x11-display-setup' and 'x11-display-closing' up front,
and stay connected to these two.

This old handling of session files looked on ~/.mutter, which has
been unused and unsupported for a long time. It also had paths were
the GError was leaked. Fix both by dropping the legacy code, and
falling back to the common error paths.

This warning is actually dead code, since should_be_mapped and
must_be_realized are always set to the same value, so it does not
make sense to check for "a && !b".
Turn this into an assert so we avoid the dead branch, but do not
remove the variable duplication so the more aptly named variable
is used where it belongs, for clarity.

When grabbing the devices, there's no error paths that would quit
late enough that both pointer and keyboard would need ungrabbing,
so the keyboard checks were dead code.
Fix this by dropping the boolean variable checks, and adding goto
labels to unroll the operation properly at every stage.

The monitor orientation tests do a lot of things in sequence. Replace
some of the comments with g_test_message() so that the log from a failed
test gives us a better idea of how far we got.

Previously, we were waiting up to 300ms for the signal, then proceeding
anyway. However, 300ms is not necessarily long enough to wait on an
autobuilder that might be heavily loaded, particularly if it's a non-x86
with different performance characteristics.
Conversely, if mutter responds to the D-Bus signal from the mock sensor
before we have connected to the signal, then we cannot expect to receive
the signal - it was already emitted, but we missed it. In this case, we
need to avoid waiting.
One remaining use of wait_for_orientation_changes() that would previously
always have timed out was in
meta_test_orientation_manager_has_accelerometer(), which does not
actually expect to see an orientation-changed signal. Make this wait
for the accelerometer to be detected instead.
