Most clients nowadays switched to buffer damage, most notably Mesa
and Xwayland. Thus lets avoid the extra cost of allocating three
`cairo_region_t`s and doing some calculations.

If no viewport is set, the neutral viewport is the surface size
without viewport destination size applied - i.e. transform and
scale applied to the buffer size. Change it accordingly, giving
us the same values we'd return in `get_width` in this case.
As result, this only changes cases where a viewport destination
size but no viewport source rectangle is set.
The change fixes exactly such cases, e.g. the Gstreamer Wayland
sink. Can be tested with: `gst-play-1.0 --videosink=waylandsink`.

When checking panel orientation on logical monitors we should take
panel orientation transform to check it's properly applied, so ensure
that we're checking the right one.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2090>
Commit 2289f56112 ("monitor-manager: Don't apply unneeded orientation
changes") added an early return to handle_orientation_change () in case
the transform is unchanged.
But this did not take the correction of the transform for devices
with 90° mounted panels into account causing a desired orientation
change to get skipped if the new orientation matches the corrected
logical orientation from the previous transform setting.
Fix this by calling meta_monitor_crtc_to_logical_transform () on the
transform before comparing it, matching the
meta_monitor_crtc_to_logical_transform () call in
create_for_builtin_display_rotation ().

When Xwayland was not initalized, we'd still clean things up. What this
accidentally meant was that the uninitialized display number 0 was
cleanud up, which very likely was main display of the host session.
What this meant in practice was that /tmp/.X11-unix/X0 was often
removed, causing every Flatpak X11 application to fail to start until
Xwayland was restarted nad the X0 socket file was restored.
Fix this in two ways: firstly only shutdown Xwayland if we ever started
it, i.e. if the X11 display policy was not 'disabled'. This should fix
the issue most of the times. Secondly only clean up the socket if it was
ever initialized. This should fix things if the socket creation failed,
as if it did, the name would be set.

A popup surface can be remapped multiple times using the same

The roundtrip in the handle-configure function could in theory (and in
practice in the future) happen to receive another configure event. If we

We created pipes for the stdout of the spawned mock services. This

(default) - where things are logged directly to /dev/null.

Since this signal is in a hot path during input handling, it makes sense
not to have this be a signal at all, currently most of the time spent in
it is in GLib signal machinery itself.
Replace it with a function/user data pair that are set on the sprite

one ::prepare-at behavior per sprite, so we can do with a single pair.

Change some things in these "app is alive" checks:
- The dialog timeout is separated from the ping timeout, in order
to show it again at a constant rate after dismissing, despite in
flight pings. It still shows immediately after the first failed
ping.
- As we want to tap further into is-alive logic, MetaWindow now
made it a property, that other places in code can fetch and
subscribe.
- Motion events trigger ping (as long as there was none other in
flight for the same window), and are counted between ping and
pong, in order to preemptively declare the window as not alive
before there is trouble with event queues being overflown.
This results in a separate logic between "the application does
not respond" and "we are showing the close dialog" so that the
former may get triggered independently.

This is a strange thing to do since MetaInputMapper also does take care of
devices with an output configured through settings, since we might have
devices that were configure through settings exclude other devices that
belong together with an output (e.g. a display-integrated tablet).
This was essentially here as a last resort to avoid matching two very
similar looking tablets to one of two very similar looking outputs. There
was a 50% chance already that the choice was wrong, and now these devices
can all be configured specifically through settings, so this shouldn't
be missed either.

This can happen if a texture was newly assigned to the actor, but the

Previously we chose to only anti-alias texels inside the boundary
(`clip_radius - 1.0`) but zoomed in you could see it was slightly smaller
than the correct curve (#2024).
Similarly if you choose to only anti-alias texels outside that edge
(`clip_radius + 1.0`) then you'd get an overly convex curve that doesn't
match up with the straight line sections.
So now we anti-alias texels that intersect the circle boundary, regardless
of which side they are mostly on. For efficiency we define "intersect" to
mean any texel whose center is within 0.5 of the theoretical edge.

When an activation times out, we'll be signalled two signals on the
startup sequence object: "timeout", and "complete".
Normally, the "complete" signal is emitted when a startup sequence is
completed succesfully by it being used for activation, and in this case,
the xdg_activation implementation should remove the sequence from the
startup notification machinery.
However, in the timeout case, we should not remove it, as the startup
notification machinery itself will deal with this. If we would, we'd end
up with use-after-free issues, as the sequence would be finalized when
removed the first time.
To avoid this, just clean up the Wayland side in the "timeout" signal
handler, leaving the "complete" signal handler early out if it was
already handled by it.
This avoids crashes like:

The previous code was trying to detect client resizes by only
considering resizes without any pending configurations as client
resizes. There can however be pending configurations that do not involve
resizing, such as ones triggered by state changes. These may also stay
unacknowledged by the client until the next size change. This was
causing client resizes after showing the window (and therefore changing
its status to focused) to not be detected as client resize.
Fix this by checking whether the queue has any configuration with size
changes rather than just whether it is empty.

Currently the stored unconstrained_rect is only ever updated if there
was a move, resize or state change according to the move_resize_internal
implementation. For Wayland windows however resizes or state changes
are done in two steps, first the new configuration is sent to the client
and then once client acknowledges it, it is set on the mutter side in
another move_resize_internal call. Only the second call would result in
the unconstrained_rect being updated.
This started causing problems when unfullscreening windows was
immediately followed by a strut change. These strut changes started
happening in gnome-shell due to the visibility of the panel now being
considered for the struts and the presence of a fullscreen causing it to
be hidden until unfullscreen. In this situation first the unfullscreen
would resize the window to its pre-fullscreen size as expected, but then
the strut change triggers another window resize. This window resize is
based on the stored unconstrained_rect, which is still at the fullscreen
size because the unfullscreen resize only has sent its configuration,
but it has not been acknowledged yet. As a result the strut change
causes a resize to the fullscreen size which due to the constraints now
looks like a maximized window.
To fix this always update the unconstrained_rect when the requested size
has changed, but not when a previous request has been acknowledged
unless it is originating from the client itself.
If this included the move_resize_internal call from acknowledging the
size as well, it would be possible for this to be delayed long enough on
the client side to overwrite an intermediate resize originating from
mutter. And if this did not include resizes originating from the client,
clients would not be able to set an initial window size.

meta_window_wayland_finish_move_resize() is called for both, finishing
a resize that has been requested through/by mutter and for resizes
directly done by the client. This introduces a CLIENT_RESIZE flag to
differentiate the former from the latter. Having this distinction is
required to know what the last requested size by either the client or
mutter is while ignoring older requests that might only have been
applied now.
This excludes client resizes when there are still pending
configurations, because the resize is known to be only temporary.

If one would end up with an actor attached to mapped actor, where the
attached actor doesn't itself have an up to date stage view list while
listening on the stage for updating, when clearing the stage views of
the list, anything that would query the stage views list at this time
would end up accessing freed memory.
This could happen if
1) An actor was added to a newly created container actor attached to
the stage
2) The actor got a timeline attached to it
3) The actor was moved to a container that already was mapped
4) A hotplug happened
After (1) both the container and actor would not have any stage views.
After (2) the timeline would listen on the stage for stage views
updates. After (3) the actor would still listen on the stage for stage
views updates. When (4) happened, the actor would be signalled when the
stage got its stage view cleared, at which point it would traverse up
its actor's tree finding an appropriate stage view to base its animation
on. The problem here would be that it'd query the already mapped
container and its yet-to-be-cleared stage view list, resulting in
use-after free, resulting in for example the following backtrace:
0) g_type_check_instance_cast ()
1) CLUTTER_STAGE_VIEW ()

12) _clutter_actor_traverse ()
13) clutter_actor_clear_stage_views_recursive ()
14) clutter_stage_clear_stage_views ()
...
Avoid this issue by making sure that we don't emit 'stage-views-changed'
signals while the actor tree is in an invalid state. While we now end up
traversing tree twice, it doesn't change the Big-O notation. It has not
been measured whether this has any noticible performance impact.

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

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

* 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.

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.

When we use gbm together with the NVIDIA driver, we want the EGL/Vulkan
clients to do the same, instead of using the EGLStream paths. To achieve
that, make sure to only initialize the EGLStream controller when we
didn't end up using gbm as the renderer backend.

This switches the order of what renderer mode is tried first, so that
the gbm renderer mode is preferred on an NVIDIA driver where it is
supported.
We fall back to still try the EGLDevice renderer mode if the created gbm
renderer is not hardware accelerated.
The last fallback is still to use the gbm renderer, even if it is not
hardware accelerated, as this is needed when hardware acceleration isn't
available at all. The original reason for the old order was due to the
fact that a gbm renderer without hardware acceleration would succeed
even on NVIDIA driver that didn't support gbm.

This replaces functionality that MetaRenderDevice and friends has
learned, e.g. buffer allocation, EGLDisplay creation, with the usage of
those helper objects. The main objective is to shrink
meta-renderer-native.c and by extension meta-onscreen-native.c, moving
its functionality into more isolated objects.

All render devices that have a device file backing them might be able to
allocate dumb buffers, so add a helper for doing that. Will indirectly
result in an error up front on a surfaceless render device due to lack
of a device file.

It might not be needed by the user of the buffer, so don't always
require it up front. Instead make sure that any user that needs it first
calls "meta_drm_buffer_ensure_fb_id()" to create the ID.
Only the plain gbm implementation creates the ID lazilly, the other
still does it on construction due to the objects used to create them
only existing during construction.

Mostly calls into gbm_bo_* API, or something somewhat similar when on
dumb buffers. Added API are:
* get offset for plane
* get bpp (bits per pixel)
* get modifier
This will allow users of MetaDrmBuffer to avoid having to "extract" the
gbm_bo to get these metadata.
