This way, we can simply pop up the Looking Glass and run:
>>> Meta.add_clutter_debug_flags(Clutter.DebugFlag.PICK, 0, 0)
And measure specific actions or events on GNOME Shell.

As we do not prevent the SwapBuffers call from happening, those also
do count. Results in clip area calculations to be right for monitors
that previously did not get invalidated.

Make ClutterActor paint using ClutterTransformNode, ClutterClip
node, and ClutterActorNode. Essencially, the actor node is a
replacement for clutter_actor_continue_paint().
An interesting aspect of this commit is that the order of the
operations is reversed to be preserved.
Before being able to remove the dummy node hack, we'll need to
make ClutterEffects compatible with paint nodes first -- and
naturally, that's enough content for its own merge request.

ClutterActorNode is a paint node that runs the 'paint'
function of an actor. It is a useful helper node to be
used during the transition to paint nodes.
The role of ClutterActorNode will change over time. For
now, it is just a call to clutter_actor_continue_paint(),
which also paints the effects. When ClutterEffect is
ported to paint nodes, ClutterActorNode will morph to
only notify the actor about the painting, and will become
a private node to Clutter.

Previously picking was done on an int (x,y) to address a particular pixel.
While `int` was the minimum precision required, it was also an unnecessary
type conversion.
The callers (input events mainly) all provide float coordinates and the
internal picking calculations also have always used floats. So it was
inconsistent and unnecessary to drop to integer precision in between those.
ABI break: This changes the parameter types for public function
`clutter_stage_get_actor_at_pos`, but its documentation is already
sufficiently vague to not need changing.

This is an extremely straightforward and minimalistic port of
CoglVector APIs to the corresponding Graphene APIs.
Make ClutterPlane use graphene_vec3_t internally too, for the
simplest purpose of keeping the patch focused.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/458
Mutter requires Clutter, which requires Cogl. That means
Clutter requires all Cogl dependencies, and Mutter requires
all Clutter dependencies as well.
However, currently, Clutter does not pull in its dependencies,
which means we need to link against Cogl manually.
Add Clutter dependencies to declare_dependency() so that the
graphene dependency only needs to be declared once, for Cogl,
and pulled together.

This is a deprecated property that is not used anywhere
in the codebase. Not by GNOME Shell. Because it uses the
deprecated ClutterGeometry type, it's a good target for
cleaning up, given that ClutterGeometry will be dropped
later on.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/458
Fog is explicitly deprecated in favour of CoglSnippet API,
and in nowhere we are using this deprecated feature, which
means we can simply drop it without any sort of replacement.

When clutter actors with key focus are destroyed we emit ::key-focus-out on
them just after their destruction. This is against our assumption that no
signal should be emitted after "::destroy" (see GNOME/mutter!769 [1]), and
in fact could cause the shell to do actions that we won't ever stop on
destroy callback.
To avoid this to happen, use a private function to set its key-state (so we
can avoid looking for the stage) and emit ::key-focus-in/out events and use
this value in both clutter_actor_has_key_focus(),
clutter_actor_grab_key_focus() and on unmap and destruction to unset the
stage key focus before we emit the ::destroy signal.
As result of this, we can now avoid to unset the key focus on actor
destruction in the stage.

Clutter had support for internal children in its early revisions, but they
were deprecated for long time (commit f41061b8df, more than 7 years ago) and
no one is using them in both clutter and in gnome-shell.
So remove any alternative code path that uses internal children.

This is for all intents and purposes the same as
`cogl_object_ref/unref`, but still refers to handles rather than
objects (while we're trying to get rid of the former) so it's a bit of
unnecessary redundant API.

The default value of the ClutterShaderEffect:shader-type
property is CLUTTER_FRAGMENT_SHADER. However, because the
struct field is not actually initialized to it, it ends
up assuming the value 0, which is CLUTTER_VERTEX_SHADER.
Properly initialize ClutterShaderEffect's shader_type to
CLUTTER_FRAGMENT_SHADER.

ClutterActor took a reference in its transition 'stopped' handler,
aiming to keep the transition alive during signal emission even if it
was removed during. This is, however, already taken care of by
ClutterTimeline, by always taking a reference during its 'stopped'
signal emission, so no need to add another one.
This also has the bonus of making reference ownership simpler, as well
as avoidance of double free if an actor was destroyed before a
transition has finished.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/828
Implicit transitions had a referenced taken while emitting the
completion signals, but said reference would only be released if it was
had remove-on-complete set to TRUE.
Change this to instead remove the 'is_implicit' state and mark all
implicit transitions as remove-on-complete. This fixes a
ClutterPropertyTransition leak in gnome-shell triggered by e.g. showing
/ hiding menus.

The final version of the function was changed to allow points that are
touching the edge of a quadrilateral to be counted as "inside". Update
the function documentation to refect this.
Also clarify that the function is written in such a way that it is
agnostic to clockwise or anticlockwise vertex ordering.

In `clutter_stage_view_blit_offscreen()`, the given clipping rectangle
is in “view” coordinates whereas we intend to copy the whole actual
framebuffer, meaning that we cannot use the clipping rectangle.
Use the actual framebuffer size, starting at (0, 0) instead.
That fixes the issue with partial repainting with shadow framebuffer
when fractional scaling is enabled.

Clutter actors might emit property changes in dispose, while unparenting.
However we assume that the ::destroy signal is the last one we emit for an
actor, and that starting from this moment the object is not valid anymore,
and so we don't expect any signal emission from it.
To avoid this, freeze the object notifications on an actor during its
disposition, just before the ::destroy signal emission.
Update the actor-destroy test to verify this behavior.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/769
Clutter actors unset their parent on dispose, after emitting the ::destroy
signal, however this could cause ::parent-set signal emission. Since we
assume that after the destruction has been completed the actor isn't valid
anymore, and that during the destroy phase we do all the signal / source
disconnections, this might create unwanted behaviors, as in the signal
callbacks we always assume that the actor isn't in disposed yet.
To avoid this, don't emit ::parent-set signal if the actor is being
destroyed.
Update the actor-destroy test to verify this behavior.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/769
If there is no transformation, use `cogl_blit_framebuffer()` as a
shortcut in `clutter_stage_view_blit_offscreen()`, that dramatically
improves performance when using a shadow framebuffer.
