MetaRendererViewNative is a MetaRendererView which contains logic
specific to views of the native backend. It will be used by following
commits.
In the future, per-view logic from MetaRendererNative can be moved to
MetaRendererViewNative where it makes more sense to have it.

Instead of using the "discarded" page flip callback when the
"discarding" happened during actual immediate processing, communicate
the same via the KMS update feedback.
The "discarded" page flip callback is instead used only for when a
posted page flip is discarded. In the atomic backend, this only happens
on shutdown, while in the simple backend, this also happens when a
asynchronous retry sequence eventually is abandoned.
This allows further improvements making KMS handling fully async.

At first it was called seal(), but then updates could be amended after
being posted, given a flag. That flag has been removed, so we can go
back to sealing, since it's once again acts more as a seal.

We test direct client buffer scanout using a TEST_ONLY commit on atomic,
and with various conditions in non-atomic, but if we end up failing to
actually commit despite this, handle the fallout asynchronously. What
this means is that we'll reschedule a new frame immediately.
For this to work, the same scanout buffer needs to be avoided for the
same CRTC. This is done by using the newly added signal on the
CoglScanout object to let the MetaWaylandBuffer object mark the current
buffer as non-working for the onsrceen that it failed on. This allows to
re-try buffers on the same onscreen when new ones are attached.
This queues a full damage, since we consumed the qeued redraw rect. The
redraw rect wasn't lost - it was accumulated to make sure the whole
primary plane was redrawed according to the damage region, whenever we
would end up no longer doing direct scanout, but this accumulation only
works when we're not intentionally stopping to scanout. For now, lets
just damage the whole view, it's just an graceful fallback in response
to an unexpected error anyway.

If we get a "ready" page flip feedback, it means the page flip was
symbolic, i.e. not real, e.g. as a result of an update that didn't
change the state of the primary plane. Warn if there is a "next fb"
meaning we expected to have a new buffer that we flipped to.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2854>
This is intended to be used only for plane assignment, and CRTC like
changes, so that one can e.g. change a cursor plane on a pending update
that changes the primary plane, before it has been committed to KMS.
The kms-updates test overrides the get-state function MetaKmsCrtc. This
is needd to not have the update mechanism not clamp the gamma size to 0,
as vkms reports the gamma length 0. By pretending it's 3, we can test a
simple and small gamma lut is merged correctly when merging updates.

Screen-casted windows need to be considered visible in various situations
but existing APIs such as `clutter_actor_is_effectively_on_stage_view()`
don't do so. Add new API that allows checking if a surface belongs to a
screen-casted window for the respective cases.

From the scale factors available to it, Mutter will now try to select
the scale factor that makes the UI's size as close as possible to the
size it would be, w/o scaling, on a display at 135 PPI (for mobile
displays) or at 110 PPI (for stationary displays)

The pointer to the manager, the peer name and the ID are things that are
always metadata related to a session, so make them properties on the
interface instead of duplicating them. The implementations still need to
keep track of them, but their existance is shared.

This class is intended to be used as a base class for D-bus interface
implementations that deal with "session" objects, i.e. a D-Bus object
representing a certain session of some kind, e.g. a screen cast session.
It handles things such as hooking up to the D-Bus client watcher,
generates IDs, handles shutdown procedures.

It's currently not set by anything, and will only be used by
non-abstract implementations of a future D-Bus interface session
manager. When interface implementations gets ported to this new type,
their MetaDbusSession implementations will set this vfunc.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2713>
This means the MetaDbusSession interface takes a more active role
instead of being something that more or less sends signals to the
interface implementor. This will allow better control when using
MetaDbusSession to manage these sessions, instead of their non-abstract
variants.

Allows for creating LUTs at some fixed size which maintains enough
precision for concatenating or otherwise manipulating the LUT without
having to care about the precision of the hardware.

If the device supports the atomic API the property based API is used to
write gamma updates and the legacy API is used in the non-atomic case.
The current state is read from the legacy API always though which can be
different from the property API. This commit always uses the correct API
to update the state.

With detach meaning having the onscreen stop listening on configuration
changes on the corresponding backing mode setting objects. We need to do
this as there is a time between rebuilding the views, and that the new
mode sets are called, where the old onscreen is kept alive, but the
stage view is gone. At this point in time, if privacy screen or gamma
configuration changes, e.g. by the night light temperature changing, the
onscreen would attempt to schedule an update on the now gone stage view.
This commit also renames the "keep onscreen alive" to "detached
onscreens" to more clearly communicate that it's detached onscreens from
their corresponding mode setting objects.

For the coordinates of pointers or stylii, we translate the ones we store
using the viewport matrix already. For touch events otoh, we store coords
untranslated and translate them later only for event emission.
Let's be consistent here and store the coordinates of touch events
translated, just like we do for pointer events.
This fixes touch window dragging on rotated monitors. MetaWindowDrag calls
clutter_seat_query_state(), which uses those stored coordinates. So in case
of a touch sequence the coords returned by query_state() would be
untranslated.

Streams are generally recoverable by the client and errors may happen
e.g. on negotiation failures. Right now we close the stream and
corresponding session, which is neither necessary nor expected by
clients.
Just disable the stream instead and let clients handle things as they
seem fit. This allows clients to e.g. try several Gstreamer pipelines
with limited caps on a single stream.

Doing it in dispose means the backend is actively tearing down itself,
meaning various components might or might not be there, depending on how
the tearing down is implemented. Make things a bit more robust by doing
any work that might rely on the backend being there before shutdown is
done in response to the 'prepare-shutdown' signal being emitted by the
backend.

The first monitor in stacking tests is the primary monitor but that
doesn't have to stay this way forever. Instead of special casing the
name "primary" to refer to whatever monitor happens to be the primary
monitor, we add an `assert_primary_monitor` command to verify that the
monitor that should be the primary monitor actually is.

The previous logic tried to keep the position of the top left corner of
the window relative to the top left corner of the monitor. This allowed
the window to move out of the target monitor. This change keeps the
proportions of the distance between the window and the monitor borders
instead if possible. Otherwise it keeps the relative position of the
center of the window clamped to [0,1] to make sure the window lands on
the right output.
This also slightly changes what monitor is considered to be on: the
monitor which contains the center of the window and, if the center is on
no monitor, the monitor wich overlaps the most with the window.
