This uses the luminance levels of the color states to anchor the white
of content instead of hard-coding the levels.
This also starts using uniforms for parts of the mapping which means we
don't have to generate and compile a shader when the luminance levels
change.

They represent the minimum and maximum luminance levels of the primary
color volume and the reference luminance level (reference white, SDR
white, ...) in the reference viewing environment.
They help anchoring the white level, optionally help with preserving the
dynamic range and help with adjusting from a "dark" to a "bright"
viewing environment.
The values have defaults which depend on the transfer characteristics.
This reflects the wayland color management protocol.

Actions might get detached sometime during event processing,
at a time that the stage did already prepare an emission chain
holding references to the actions and actors that need to handle
events. This means actions might become detached, but still handle
the incoming event, or possible crossing events generated in-place
when the actor becomes unparented.
Avoid this situation, by skipping event handling on actions that
went detached, we will just instruct to continue event processing.

Instead, get it from the context. See next commit
For ClutterText, we had to switch to using constructed
as the ClutterContext will be set for the ClutterActor in the
constructor phase

See previous commit log on the effects of this.
This means the deadline evasion needs to be added in both cases in
clutter_frame_clock_notify_presented.

As a writable property, nothing sets it in both Mutter/GNOME Shell
making it a dead-code. As we will be moving pango related bits to
gnome-shell, remove this one already
Removes pango-ft2 dependency

As GNOME Shell always sets that to FALSE anyways
This does not drop the separate caching whether the mipmapping is
disabled or not, in case shell wants to make use of that in the future

And stop passing in the color states from the RendererNative. We also
keep the color states updated by listening for changes in the color
device.
The RendererX11Cm has a single view and no mapping to a specific color
device, so we handle the absense of a color device as well and rely on
ClutterStageView to have the default color states.

This allows us to destroy and create a new offscreen dynamically, when
the rotation or color state changes.
An idle gsource with priority higher than CLUTTER_PRIORITY_REDRAW is
used to ensure the an offscreen exists when required without having to
allocate in the redraw process.

Currently, we would only disable a11y if a certain flag is passed
but the function is always called with NONE flag. Instead
drop the flag, use a new environment variable for that
That value is then used by actors to short-circuit get_accessible
implementation and return NULL if the accessibility is not enabled
Also clean the other accessibility functions

As GNOME Shell has a more complete solution with StScrollable /
StViewport / StScrollbar and does not make use of the Clutter actor.
We might want to "upstream" GNOME Shell infrastructure later at some
point but the current "solution" is too poor, so just drop it
