`gdctl show` now prints "monitor preferences", which currently consists
of only the luminance setting.
`gdctl prefs` is introduced, where one can run e.g. `gdctl prefs
--monitor DP-1 --luminance 80.0` to set the output luminance of the
monitor connected to DP-1 to 80%.

This replaces the DISPATCHED state with new sub-states that are possible
with triple buffering:
DISPATCHED_ONE: Double buffering
DISPATCHED_ONE_AND_SCHEDULED: Scheduled switch to triple buffering
DISPATCHED_ONE_AND_SCHEDULED_NOW: Scheduled switch to triple buffering
DISPATCHED_ONE_AND_SCHEDULED_LATER: Scheduled switch to triple buffering
DISPATCHED_TWO: Triple buffering
Triple buffering is currently disabled until the test cases get updated to
handle it in the next commit.

Chronologically they already overlap in time as presentation may
complete in the middle of the dispatch function, otherwise they are
contiguous in time. And most switch statements treated the two states
the same already so they're easy to merge into a single `DISPATCHED`
state.
Having fewer states now will make life easier when we add more states
later.

Although since all SCHEDULED* states basically have the same transitions
it's easier to show them as a single state. The mermaid diagram also won't
render correctly if there is a mix of combined and singular states. We
must use either always combined states or always singular states.

As that is where the whole text rendering integration happens
And would allow us to get rid of some over-abstraction in cogl-pango,
simplify
ClutterSnapshot integration as well

Except the X11 backend test, it still needs an X server. Eventually we
can replace it with the equivalent that uses Xwayland, but that needs a
"scaled down" mutter that runs as the host compositor for Xwayland, that
doesn't expose anything on the session bus.

The new CLUTTER_FRAME_CLOCK_STATE_SCHEDULED_NOW state is almost
identical to CLUTTER_FRAME_CLOCK_STATE_SCHEDULED, with one important
difference being that it avoids updates from being repeatedly
rescheduled "now" when multiple calls to
clutter_frame_clock_schedule_update_now() are done before the source
is actually dispatched.
Such repeated calls to schedule an update "now" may actually postpone
the dispatch if the CPU is very busy and the source dispatch is
delayed, defeating the purpose of scheduling a frame "now".
It also allows rescheduling "now" when the frame clock is uninhibited
after being inhibited while an update was scheduled "now". This may
be important in cases where the frame clock is inhibited for very
short periods in which it would otherwise lose the state of being
scheduled "now".
Scenarios such as this would become more common with the introduction
of variable refresh rate since it makes scheduling "now" a commonplace
occurrence.

Eventually we want to have all the high-level code documentation in the
component API reference documentation. However, gi-docgen is currently
missing support for mermaid so we just keep the files in `doc/` and link
to them from `code-overview.md`.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3505>
Let's try to consolidate our documentation in doc/ in the repo. This
includes some documentation from README.md, the HACKING.md coding style
and the gitlab wiki.
The README.md file now links to all top-level topics (i.e. not reachable
via other topics).
This also includes a few small changes to make things more consistent.

Currently, Meta/Cogl/Clutter makes use of cairo_rectangle_int_t despite
the existance of MetaRectangle.
In order to make MetaRectangle usable in Cogl/Clutter as well, Mtk would
provide such base types that are shared across the various private
libraries

Since MetaWindowDrag took a lot of this code to handle window drags
internally with less interactions with the rest of the stack, this
code in display/window/keybindings is unused.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2683>
Flip the switch in using MetaWindowDrag, leaving display grab
ops and a bunch other code unused. Some places checked the grab op
and/or window in complex ways, others just checked for grab existence
and should now look for clutter ones, and others already were already
doing this in addition.
