The final tick of a timeline is >= its duration, but when using ticks that
are slightly in the future ("next presentation time") this means the final
tick will execute and complete the timeline up to one frame interval before
the timestamp of that final tick.
For the single clock test we now just check if the overall duration is
within one frame of the expected timeline duration.
The dual clock (switching) test needs a threshold of two frames because
starting each new clock creates a phase shift (error) of up to one frame.

We're in the destructor, it's pointless to unset the userdata as we'll
never ever see a request being invoked with it ever again, since the
resource itself will be destroyed or marked as destroyed.

When rendering to a buffer that is not the stage view buffer, we can not
know where the buffer will be displayed on the screen. As a result we
also can not know what translation would need to be applied to culling.
This was causing glitches when the gnome-shell magnifier was applying
offscreen effects. ClutterOffscreenEffect causes MetaWindowGroup to be
rendered to an offscreen buffer at an offset, because it draws to a
slightly larger texture with an accordingly translated origin. This
translation then later is canceled out again when the offscreen buffer
is drawn. To meta_actor_painting_untransformed() however which only sees
the translation used when drawing to the buffer this looked like the
window group was being rendered at the offset. This then lead to
redraw_clip getting translated accordingly, resulting in wrong
coordinates used for culling.
Similarly this was leading to issues when taking area screenshots while
at 1x zoom.

Refresh rates >60Hz become ever more common. In order to allow users
to keep hight refresh rates when not running at a natively advertized
resolution, add common refresh rates to our fallback modes.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2189>
Right now we often add a duplicate fallback mode that's almost
identical to the native mode. This adds unnecessary clutter to
UIs, thus filter out such modes.
In order to keep the code small, use `MetaCrtcModeInfo` directly
instead of recalculating the values. And to keep consistency, do
the same in the loop above.

This is so that it can unregister from it on tear down. The tracker owns
references to cursors too, but this cycle is already broken as the
backend calls 'g_object_run_dispose()' when tearing the cursor tracker
down.

An incorrect assumption that after mode set there would be no pending
page flips was made. This meant that if there was a mode set, followed
by a page flip, if that page flip was for a CRTC on a now unused GPU,
we'd crash due to the renderer GPU data having already been freed. This
commit avoids that by keeping it alive as long as the page flips are
still in the air. It fixes crashes with backtraces such as

During tear down, if anything teared down after the seat tries to get
the cursor renderer, we'd crash trying to get it as the seat would
already be gone. Avoid this by returning NULL when there is no seat.
It's assumed that any path that will happen during tear down that relies
on getting the cursor renderer will gracefully handle it not being
present, e.g. by relying on the cursor rendering cleaning up itself.

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.

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
wl_surface, if a new xdg_popup object is created. To properly handle
this, we need to reset the 'dismissed_by_client' boolean to false, as
otherwise we won't allow new buffer commits.

The roundtrip in the handle-configure function could in theory (and in
practice in the future) happen to receive another configure event. If we
send yet another invalid geometry the second time, we log one time too
many in the server, which fails the test. Avoid this by ignoring the
second configure event; it's enough to pass through the error handling
path once.
