When the stage views the stage is shown on are changed, ClutterStage
currently provides a clutter_stage_update_resource_scales() method
that allows invalidating the resource scales of all actors. With the new
stage-views API that's going to be added to ClutterActor, we also need a
method to invalidate the stage-views lists of actors in case the stage
views are rebuilt and fortunately we can re-use the infrastructure for
invalidating resource scales for that.
So since resource scales depend on the stage views an actor is on,
rename clutter_stage_update_resource_scales() and related methods to
clutter_stage_clear_stage_views(), which also covers resource scales.

While the layout manager of a ClutterActor does get properly unset when
destroying an actor, we currently forget to disconnect the
"layout-changed" signal from it.
So do that, and while at it, also switch to using the signal id for
disconnecting from the signal instead of
g_signal_handlers_disconnect_by_func(), which caused problems before
because it might traverse the signal handler list.

We currently are confusing g_param_spec_enum and g_param_spec_flags for
the offscreen-redirect property of ClutterActor. Since it's actually a
flag, make it a flag everywhere.
Fun fact: This was already partly done with
d7814cf63e, but that commit missed the
setter.

Just like the ClutterBindConstraint, the ClutterAlignConstraint should
listen to "queue-relayout" of its source actor, not
"notify::allocation". That's because the latter will queue a relayout
during an allocation cycle and might cause relayout loops.

When an app disappears after some data from it has been copied to the
clipboard, the owner of the clipboard selection becomes a new memory
selection source. The initial reference this new selection source is
never unref'ed, which leads to this being leaked on the next clipboard
selection owner change.

Using XDG_CONFIG_HOME allows users to place their keyboard configuration into
their home directory and have them loaded automatically.
libxkbcommon now defaults to XDG_CONFIG_HOME/xkb/ first, see
https://github.com/xkbcommon/libxkbcommon/pull/117
However - libxkbcommon uses secure_getenv() to obtain XDG_CONFIG_HOME and thus
fails to load this for the mutter context which has cap_sys_nice.
We need to manually add that search path as lookup path.
As we can only append paths to libxkbcommon's context, we need to start with
an empty search path set, add our custom path, then append the default search
paths.
The net effect is nil where a user doesn't have XDG_CONFIG_HOME/xkb/.

Hiding a compositor stage is not something that's really supported, but
will still be used by tests, to get closer to a "fresh" stage for each
test case, when the tests eventually start using the mutter provided
stage.
It'll use that stage simply because creating standalone stages isn't
supported.

The script parser only included G_PARAM_CONSTRUCT_ONLY parameters when
constructing objects. This causes issues if an object requires a
parameter to be set during construction, but may also change after. Fix
this by including G_PARAM_CONSTRUCT parameters when constructing script
objects as well.

We would get the MetaDisplay from the backend singleton before creating
the MetaCompositor, then in MetaCompositor, get the backend singleton
again to get the stage. To get rid of the extra singleton fetching, just
pass the backend the MetaCompositor constructors, and fetch the stage
directly from the backend everytime it's needed.
This also makes it available earlier than before, as we didn't set our
instance private stage pointer until the manage() call.

Start follow the convention used in ClutterFrameClock by including the
meaning as well as time granularity in the variable name. The
constructor takes the intended duration of the constructed timeline in
milli seconds, so call the constructor argument `duration_ms`. This is
done in preparation for adding more constuctors.

Also fix a test that dependends on a specific element order in a list
that wasn't defined to have any particular order.
The frames per second is decreased from 30 to 10, to make the test less
flaky when running in CI.

The shadow was disabled for the X11 client as it was far to unreliable
when comparing sizes.
It seems that the Wayland backend has been somewhat unreliable as well,
where some race condition causing incorrect sizes thus a flaky test.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1288
A "show" command calls gtk_window_show() and gdk_display_sync(), then
returns. This means that the X11 window objects are guaranteed to have
been created in the X11 server.
After that, the test runner will look up the window's associated
MetaWindow and wait for it to be shown.
What this doesn't account for is if mutter didn't get enough CPU time to
see the new window. When this happens, the 'default-size' stacking test
sometimes failed after hiding and showing the X11 window.

If a test is not expected to succeed, then running it could be considered
to be a waste of resources, particularly if the failure might manifest
as an indefinite hang (see cogl!11), or if the test is likely to dump core
and trigger "expensive" crash-reporting mechanisms like systemd-coredump,
corekeeper, abrt or apport.
Skip the tests that are expected to fail. They can still be requested via
an environment variable, which can be set after fixing a bug to check which
tests are now passing.
Originally cogl!15, adapted for mutter's fork of cogl to use gboolean
instead of CoglBool.

For actors which don't have needs_allocation set to TRUE and where the
new allocation wouldn't be different from the old one, the allocate()
vfunc doesn't have to be called. We still did this in case a parent
actor was moved though (so the absolute origin changed), because we
needed to propagate the ABSOLUTE_ORIGIN_CHANGED allocation flag down to
all actors.
Since that flag is now removed and got replaced with a private property,
we can simply notify the children about the absolute allocation change
using the existing infrastructure and safely stop allocating children at
this point.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1247
With commit 0eab73dc2e we introduced an optimization of not doing
allocations for actors which are hidden. This broke the propagation of
absolute origin changes to hidden actors, so if an actor is moved while
its child is hidden, the child will not get
priv->needs_compute_resource_scale set to TRUE, which means the resource
scale won't be updated when the child gets mapped and shown again.
Since we now have priv->absolute_origin_changed, we can simply check
whether that is TRUE for our parent before bailing out of
clutter_actor_allocate() and if it is, notify the whole hidden sub-tree
about the absolute origin change.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1247
Since clutter_stage_set_viewport() is only used inside clutter-stage.c
anyway, we can make it a static method. Also we can remove the x and y
arguments from it since they're always set to 0 anyway.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1247
When getting the last allocation using
clutter_actor_get_allocation_box(), Clutter will do an immediate
relayout of the stage in case an actor has an invalid allocation. Since
the allocation is always invalid when the allocate() vfunc is called,
clutter_stage_allocate() always forces another allocation cycle.
To fix that, stop comparing the old allocation to the new one to find
out whether the viewport changed, but instead use the existing check in
_clutter_stage_set_viewport() and implement the behavior of rounding the
viewport to the nearest int using roundf() (which should behave just as
CLUTTER_NEARBYINT()) since we're passing around floats anyway.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1247
When manipulating the allocation of a ClutterActor from an allocate()
vfunc override, clutter_actor_set_allocation() is used to let Clutter
know about the changes.
If the actors allocation or its absolute origin did not change before
that, this can also affect the actors absolute_origin_changed property
used by the children to detect changes to their absolute position.
So fix this bug (which luckily didn't seem to affect us so far) and set
priv->absolute_origin_changed to TRUE in case the origin changes inside
clutter_actor_set_allocation_internal(). Since this function is always
called when our allocation changes, we no longer need to update
absolute_origin_changed in clutter_actor_allocate() now.
Since a change to the absolute origin always affects the resource scale,
too, we also need to move that check from clutter_actor_allocate() here
to make sure we update the resource scale.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1247
Since the introduction of the shallow relayout functionality it's
possible to start an allocation cycle at any point in the tree, not only
at the stage. Now when starting an allocation at an actor that's not the
stage, we'd still look at the absolute_origin_changed property of this
actors parent, which might still be set to TRUE from the parents last
allocation.
So avoid using the parents absolute_origin_changed property from the
last allocation in case a shallow relayout is being done and always
reset the absolute_origin_changed property to FALSE after the allocation
cycle.
This broke with the removal of the ABSOLUTE_ORIGIN_CHANGED
ClutterAllocationFlag that was done in commit dc8e5c7f.

When we created the DMA buffer backed CoglFramebuffer, we handed it over
to CoglDmaBufHandle which took its own reference. What we failed to do
was to release our own reference to it, effectively leaking it.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1283
The stream will clean up the buffers, so let it do that before we
destroy them under its feet. Note that it'll only do this after the
following PipeWire commit:

wait_reconfigure ensures that the whole configure back and forth
completes before continuing. Doing this after every state change ensures
that we always end up with the expected state, thus fixes flakyness of
the restore-position stacking test.

This cannot be made to work reliably. Some factoids:
- Internal devices may be connected via USB.
- The ACPI spec provides the _PLD (Physical location of device) hook to
determine how is an USB device connected, with an anecdotal success
rate. Internal devices may be seen as external and vice-versa, there is
also an "unknown" value that is widely used.
- There may be non-USB keyboards, the old "AT Translated Set 2 Keyboard"
interface does not change on hotplugging.
- Libinput has an internal series of quirks to classify keyboards as
internal of external, also with an "unknown" value.
These heuristics are kinda hopeless to get right by our own hand. Drop
this external keyboard detection in the hope that there will be something
more deterministic to rely on in the future (e.g. the libinput quirks
made available to us directly or indirectly).
