d29c8e290c clutter/frame-clock: Add explicit destroy function
The frame clock owner should be able to explicitly destroy (i.e. make
defunct) a frame clock, e.g. when a stage view is destructed. This is so
that other objects can keep reference to its without it being left
around even after stopped being usable.

a9a9a0d1c5 clutter: Paint views with individual frame clocks
Replace the default master clock with multiple frame clocks, each
driving its own stage view. As each stage view represents one CRTC, this
means we draw each CRTC with its own designated frame clock,
disconnected from all the others.

For example this means we when using the native backend will never need
to wait for one monitor to vsync before painting another, so e.g. having
a 144 Hz monitor next to a 60 Hz monitor, things including both Wayland
and X11 applications and shell UI will be able to render at the
corresponding monitor refresh rate.

This also changes a warning about missed frames when sending
_NETWM_FRAME_TIMINGS messages to a debug log entry, as it's expected
that we'll start missing frames e.g. when a X11 window (via Xwayland) is
exclusively within a stage view that was not painted, while another one
was, still increasing the global frame clock.

Addititonally, this also requires the X11 window actor to schedule
timeouts for _NET_WM_FRAME_DRAWN/_NET_WM_FRAME_TIMINGS event emitting,
if the actor wasn't on any stage views, as now we'll only get the frame
callbacks on actors when they actually were painted, while in the past,
we'd invoke that vfunc when anything was painted.

37326e4a32 compositor: Use stage signals instead of clutter repaint callbacks
The repaint callbacks are not tied to repaint, thus a bit misleading.
What the functionality in the pre/post-paint callbacks here cares about
is when actually painting; the non-painting related parts has already
moved out to a *-update signal.

This also renames the related MetaWindowActorClass vfuncs, to align with
naming convention of the signals that it listens to.

8cff3b84f7 wayland/compositor: Process frame callbacks on 'after-update'
Instead of going via MetaCompositor to know about when we updated
(confusingly named post-paint), use the new stage signal directly.

Note that this doesn't change the time frame callbacks are dispatched;
it's still not tied to actual painting even though it seemed so before
given the function names.

551101c65c compositor-x11: Move synchronization to before-update
The synchronization must happen no matter the painting, as it in itself
might result in reported damage, making the stage actually painted. Thus

110ed7ff8a laters: Use 'before-update' signal from stage
Instead of the 'pre-paint' signal on MetaCompositor, rely directly on
the 'before-update' signal on the stage. A reason for this is that the
callback should not only invoked in connection to painting, but updating
in general. Currently the 'pre-paint' signal is emitted no matter
whether there were any painting or not, but that's both misleading and
will go away.

2afe3e9223 clutter/stage: Add signals for different update stages
Right now the stage only had a signal called 'after-paint' which was not
tied to painting but updating. Change this to offer 4 signals, for the 4
different stages:

 * before-update - emitted in the beginning before the actual stage
   updating

 * before-paint - emitted before painting if there will be any stage
   painting

 * after-paint - emitted after painting if there was any stage painting

 * after-update - emitted as a last step of updating, no matter whether
   there were any painting or not

Currently there were only one listener, that should only really have
been called if there was any painting, so no changes to listeners are
needed.

847e89d31f clutter/frame-clock: Handle reschedule then dispatch results in idle
A frame clock dispatch doesn't necessarily result in a frame drawn,
meaning we'll end up in the idle state. However, it may be the case that
something still requires another frame, and will in that case have
requested one to be scheduled. In order to not dead lock, try to
reschedule directly if requested after dispatching, if we ended up in
the idle state.

2a6e8bda8d cogl/onscreen: Let swap buffer caller create frame info
We currently have mutter set a global frame counter on the frame info in
the native backend, but in order to do this from clutter, change the
frame info construction from being implicitly done so when swapping
buffers to having the caller create the frame info and passing that to
the swap buffers call.

While this commit doesn't introduce any other changes than the API, the
intention is later to have the caller be able to pass it's own state
(e.g. the global frame count) along with the frame info.

fc0b8f9d9c laters: Use clutter_stage_schedule_update() instead of timeline
The MetaLater functionality needs to make sure an update is scheduled so
that it can run its callbacks etc. This used a ClutterTimeline (which is
an object more or less meant to drive animations markers, frames etc)
just to keep the master frame clock running. We're moving away from a
single master clock, so just schedule updates directly instead, with the
newly exposed API.

3944daf3c0 clutter/stage: Find devices to update after finish queue redraw
Devices are updated (repicked) as part of the stage update phase, as
their stacking, position and transform might have changed since since
the last update.

The redraw clip was used to avoid unnecessary updating of devices, if
the device in question had it's position outside of the redraw clip. If
the device coordinate was outside of the redraw clip, what was
underneith the device couldn't have changed.

What it failed to do, however, was to update devices if a relayout had
happened in the same update, as it checked the state whether a layout
had happened before attempting to do a relayout, effectively delaying
the device updating to the next update.

This commit changes the behavior to always update the device given the
complete redraw clip caused by all possible relayouts of the same update
as the device update happens in.
