The modifier state of the input device is supposed to be set to the
newest state, while the modifier state detail of the event is set to the
last state before the event (so not including the changes triggered by
the event).
So since the modifier state of the event is the last state anyway, the
state of the ClutterInputDevice is supposed to be set by the backend and
not by the stage while queuing the event, so stop setting the state
here.

Make the clutter_input_device_get_actor() API public and remove
clutter_input_device_get_pointer_actor() in favour of the new function.
This allows also getting the "pointer" actor for a given touch sequence,
not only for real pointer input devices like mice.

Switch from clutter_seat_list_devices() to the new peek_devices() method
of ClutterSeat in cases where we're only looping through the returned
list without manipulating it. This way we don't have to unnecessarily
copy around the list of devices.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1275
Add a method to ClutterSeat that allows peeking the list of input
devices and allow looping through devices a bit faster. The API left is
private so we can make use of peeking the GList internally, but don't
have to expose any details to the outside, which means we'd have to
eventually stick with a GList forever to avoid breaking API.
Since we now have the peek_devices() API internally, we can implement
ClutterSeats public list_devices() API using g_list_copy() on the list
returned by peek_devices().

While it's strongly discouraged, it is possible to queue a new relayout
of an actor in the middle of an allocation cycle, we warn about it but
don't forbid it.
With the introduction of the "shallow relayout" API, our handling of
those relayouts silently changed: Before introducing "shallow
relayouts", we'd handle them on the next stage update, but with the
priv->pending_relayouts hashtable and the
priv->pending_relayouts_version counter, we now do them immediately
during the same allocation cycle (the counter is increased by 1 when
queuing the relayout and we switch to a new GHashTableIter after
finishing the current relayout, which means we'll now do the newly
queued relayout).
This change in behavior was probably not intended and wasn't mentioned
in the commit message of 5257c6ecc2, so
switch back to the old behavior, which is more robust in preventing
allocation-loops. To do this, use a GSList instead of GHashTable for the
pending_relayouts list, and simply steal that list before doing the
relayouts in _clutter_stage_maybe_relayout().

As explained in the last commits, we'll let gnome-shell take care of
this since freezing and thawing needs to be decoupled from the effect
starting and ending.
So stop freezing the MetaWindowActor when starting the effect and
thawing the actor when ending the effect.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1250
As explained in the last commit, gnome-shell needs to be able to thaw
window actor updates during its size-change effect is active.
So make meta_window_actor_freeze() and meta_window_actor_thaw() public
API, which will allow the shell to freeze and thaw actor updates itself.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1250
The size-change animation in gnome-shell needs to sync the window actors
geometry during the animation, it currently does this by notifying the
compositor that the animation was finished before it actually is.
This causes a few bugs in Mutter though, since it will now emit the
"effects-completed" signal on the window actor even though they aren't
completed.
To fix that, we need to decouple freezing and thawing of actor updates
from window effects and allow gnome-shell to thaw actor updates before
it notifies Mutter that the effect is completed.
The first step for this is allowing to sync the actor geometry while an
effect is active, this should be redundant since effects which actually
need to inhibit those updates will freeze the actor anyway. Also a
geometry change happening while another effect is active will kill the
old effect anyway because MetaPluginManager kills all the active window
effects before starting a new one; so the new size-change effect for any
geometry change is going to kill the current effect.

ClutterAlignConstraint currently assumes the source actor is positioned
in the same coordinate system as the actor it's attached to and
automatically offsets the adjusted allocation by the origin of the
source actor.
This behavior is only valid though in case the source actor is a sibling
of the constraint actor. If the source actor is somewhere else in the
actor tree, the behavior gets annoying because the constraint actor is
offset by (seemingly) random positions.
To fix this, stop offsetting the constraint actors allocation by the
position of the source.
To still make it possible to align the constraint actors origin with the
origin of the source, no longer override the origin of the allocation
in the AlignConstraint. This allows users to align the origin using a
BindConstraint, binding the actor position to the position of the
source, which is more flexible and also more elegant.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/737
Add a new pivot-point property to the ClutterAlignConstraint, similar to
the pivot point used by ClutterActor, defining the point in the
constraint actor around which the aligning is applied to the actor.
Just as the ClutterActor property, this property is defined using a
GraphenePoint.
By default this property remains set to (-1, -1) and the actor
will always be aligned inside the source actor, preserving the existing
behavior of ClutterAlignConstraint.

Trying to figure out what this comment was actually about, it turns out
that MSC means Media Stream Counter, and as mentioned in an article[0]
is related to DRI3 and the X11 Present extension. Anyway, the comment
has been there raising questions for some years now, I think we can
remove it.

The ID and name are just moved into the instance private, while the rest
is moved to a `MetaCrtcModeInfo` struct which is used during
construction and retrieved via a getter. Opens up the possibility to
add actual sub types.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1287
Just as with MetaOutput, instead of the home baked "inheritance" system,
using a gpointer and a GDestroyNotify function to keep the what
effectively is sub type details, make MetaCrtc an abstract derivable
type, and make the implementations inherit it.

It's used for two things: avoid reading configs, and actual hotplug
update mode. The former requires the suggested position to be (-1, -1)
to trick the monitor configuration generator to skip using the suggested
position even if hotplug update mode is set to TRUE. The latter should
use the actual hotplug mode coordinates.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1287
Now set as a property during construction. Only actually set by the
Xrandr backend, as it's the only one currently not supporting all
transforms, which is the default.
While at it, move the 'ALL_TRANFORMS' macro to meta-monitor-tranforms.h.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1287
The output info is established during construction and will stay the
same for the lifetime of the MetaOutput object. Moving it out of the
main struct enables us to eventually clean up the MetaOutput type
inheritence to use proper GObject types.

MetaCrtcInfo and MetaOutputInfo did not represent information about
MetaCrtc and MetaOutput, but the result of the monitor configuration
assignment algorithm, thus rename it to MetaCrtcAssignment and
MetaOutputAssignment.
The purpose for this is to be able to introduce a struct that actually
carries information about the CRTCs and outputs, as retrieved from the
backend implementations.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1287
That is is_presentation, is_primary, is_underscanning and backlight.
The first three are set during CRTC assignment as they are only valid
when active. The other is set separately, as it is untied to
monitor configuration.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1287
It was used during configuration to ensure that we always dealt with
every output and CRTC. Do this without polluting the MetaOutput and
MetaCrtc structs with intermediate variables not used by the
corresponding types themself.

Now that we have a proper way to mark our allocation as uninitialized,
make use of that and only disallow implicit transitions of the
"allocation" property if that is the case.
This fixes a bug where easing the allocation of an actor is impossible
when someone queued a relayout on it (or a child of it) before.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1290
We currently initialize the ClutterActorBox of the actors allocation to
zero, but there's a difference between a valid zero-allocation and an
actor having never been allocated. Currently it's impossible for us to
detect the latter case in a reliable way and we use the needs_allocation
flag for this, which may also be set in other situations.
So initialize the allocation of actors to the newly added UNINITIALIZED
ClutterActorBox, which will make it easier to detect whether an actor
already got its initial allocation.
This also fixes another issue right now: Actors which get allocated a
(valid) zero allocation, will now notify the "allocation" property in
this case.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1290
Add support for an artificial UNINITIALIZED marking for ClutterActorBox,
done by setting the boxes origin to Infinity and its size to -Infinity.
That is a value that's considered an invalid allocation by Clutter and
which can never be set by sane code.
This will allow setting the allocation of ClutterActors to an
UNINITIALIZED box when creating actors or when removing them from the
scenegraph and makes it possible to explicitely detect uninitialized
allocations, which is useful in a few cases.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1290
The current code assumes that the actor will always have the same
size and position of the background texture, but part of the implicit
contract of being a ClutterContent is being able to render itself
at any given actor, at any given size.
For example, if the current code is given an actor with 0x0+100+100
as geometry, and no clipped region, it'll render not the whole
background, but the 0x0+100+100 rectangle of the background. In
practice, the actor geometry acts like a "clip mask" over the
background texture, due to the assumption that the actor will
always have the same size of the monitor.
Make the calculation of the texture slices relative to the actor
box.
