If the EGL header is not new enough, it will not contain that relatively
new macro definition, so to avoid breaking compilation, define it
ourselves for now. Should be possible to remove after some time.

We save the window rect before going fullscreen to a dedicated variable,
so we can go back to the correct dimension. We also have a dedicated
variable for returning from other window states, e.g. maximized, and
this one we initialized when creating the MetaWindow. This meant that we
could always rely on this being up to date on X11 windows that were
mapped maximized or fullscreen.
What the commit that introduced the saved rect dedicated for going
unfullscreen missed was to initialize the new saved rectangle too when
creating the MetaWindow. This resulted in windows mapped as fullscreen
often ending up misbehaving when unfullscreening, as mutter would tell
them to unfullscreen to 0x0.

Since every input stream now uses its own window, the X property used to
transfer the data no longer has to be unique, so we can stop generating
those unique names. This avoids creating a new atom for every transfer
since those are never freed, neither on the shell nor on the server
side. Also don't unnecessarily duplicate other strings that are
(almost) never used and get them from the atom in the rare case when
they are needed.

When there are two (or more) concurrent XConvertSelection requests with
the same target, selection and window and the data is large enough for
SelectionNotify events to overlap. This can result in the affected streams
being considered completed without any data being transferred.
While regular mutter/shell code does not make use of concurrent
XConvertSelection requests with the same targets, some extensions might.
Such as for example a clipboard manager that like the built-in clipboard
manager tries to read the selection on owner-changed.
One potential solution would be to make sure the event is for the correct
property, but not all clients seem to support concurrent requests for the
same targets but different properties on the same window.
This commit instead changes the streams to use their own window which
seems to be more widely supported.

This is a preparation for each input stream creating its own window. It
moves deleting the property from meta_x11_selection_input_stream_xevent
where it can run after the stream has been finalized to a spot where
the stream still exists. Use an error trap in case the property was not
set by the client, such as when the conversion failed.

This significantly increases the chance of a fullscreen surface buffer
being scanned out instead of being painted via composition. This is
assuming the client supports the DMA buffer feedback Wayland protocol.

This API can be used to construct a MetaKmsUpdate with plane assignments
that in isolation will be tested against the current KMS state. How it
is tested depends on the KMS implementation; in the simple / legacy KMS
backend, the tests are identical to the current scanout requirements
(dimension, stride, format, modifiers, all must match), and with atomic
KMS, it uses the TEST_ONLY on a real constructed atomic mode setting
commit.

Whenever a surface is promoted as a scanout candidate by
MetaCompositorNative, it'll get a CRTC set as the candidate CRTC.
When a client asks for DMA buffer surface feedback, use this property to
determine whether we should send a scanout feedback tranche.

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

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`.
