This allows for some further cleanups, since it is the sole consumer of

9db9793f33 clutter: Clarify clutter_stage_get_actor_at_pos docs
When a user moves their cursor the perceived behaviour is that it will
pick what is under the cursor. However this isn't how picking works.
Picking does a virtual redraw of the screen, so in some cases what gets
picked isn't the same as what the user could see on the previous frame.
It more represents what will be drawn on the next frame than what is on
screen at present.

It may be unsafe to change these semantics, and they are useful anyway.
Just document it better.

clutter/stage-cogl: Protect against extremely high refresh rates
After 4faeb12731, the maximum time allowed for an update to happen
is calculated as:

  max_render_time_allowed = refresh_interval - 1000 * sync_delay;

However, extremely small refresh intervals -- that come as consequence
to extremely high refresh rates -- may fall into an odd numerical range
when refresh_interval < 1000 * sync_delay. That would give us a negative
time.

To be extra cautious about it, add another sanity check for this case.

Change suggested by Jasper St. Pierre.

clutter/master-clock: Remove fallback throttles
The presentation timing logic (via `master_clock_get_swap_wait_time`) now
works unconditionally. By "works" we mean that a result of zero from
`master_clock_get_swap_wait_time` actually means zero now. Previously
zero could mean either a successful result of zero milliseconds or that
the backend couldn't get an answer. And a non-zero result is the same as
before.

This works even if the screen is "idle" and even if the backend doesn't
provide presentation timestamps. So now our two fallback throttling
mechanisms of relying on `CLUTTER_FEATURE_SWAP_THROTTLE` and decimating
to `clutter_get_default_frame_rate` can be deleted.

clutter/stage-cogl: Reduce while loop iterations
If `last_presentation_time` is zero (unsupported) or just very old
(system was idle) then we would like to avoid that triggering a large

without iterating.

clutter/stage-cogl: Stop schedule_update repeatedly returning now
That could happen if the backend did not provide presentation timestamps,
or if the screen was not changing other than the hardware cursor:

  if (stage_cogl->last_presentation_time == 0||
      stage_cogl->last_presentation_time < now - 150000)
    {
      stage_cogl->update_time = now;
      return;
    }

By setting `update_time` to `now`, master_clock_get_swap_wait_time()
returns 0:

  gint64 now = g_source_get_time (master_clock->source);
  if (min_update_time < now)
    {
      return 0;
    }
  else
    {
      gint64 delay_us = min_update_time - now;
      return (delay_us + 999) / 1000;
    }

However, zero is a value unsupported by the default master clock
due to:

  if (swap_delay != 0)
    return swap_delay;

All cases are now handled by extrapolating when the next presentation
time would be and calculating an appropriate update time to meet that.

We also need to add a check for `update_time == last_update_time`, which
is a situation that just became possible since we support old (or zero)
values of `last_presentation_time`. This avoids getting more than one
stage update per frame interval when input events arrive without
triggering a stage redraw (e.g. moving the hardware cursor).

1d76eace1e clutter: Hook up pointer accessibility
When using evdev (for Wayland), the backend receives all device events
and queue them for clutter.

Hook up the pointer accessibility handlers in clutter's main processing
queue, so that we get better accuracy for pointer location.

We need to avoid doing this on X11 though because X11 relies on the raw
events for this to work reliably, so the same is already done in the
X11 backend when using X11.

a859d76c72 meson: Cleanup debug build handling

This allows custom build configurations to behave like a debug or release build.

Add `-fno-omit-frame-pointer` to Mutter/Cogl. Not to Clutter though, as that would
require more changes to how Clutter's gir is created

Remove `-DG_DISABLE_CAST_CHECKS` from Clutter in debug builds

Add `-DG_DISABLE_CHECKS`, `-DG_DISABLE_ASSERT` and `-DG_DISABLE_CAST_CHECKS` to all
non-debug builds but `plain`, which explicitly should not have any compile flags

Use `cc.get_supported_arguments`, so it becomes more obvious to the user which flags
are set during compilation

f99cd18254 clutter/tests/actor-destroy: Check destroying the actor clears the children
Commit df7d8e2cb highlights a crash on test_destroy_destroy, in fact it could
happen that calling clutter_actor_destroy on a child while iterating on the
list, would implicitly call test_destroy_remove that tries to modify the list
at the same time. Causing a memory error.

So instead of manually free the children list, just ensure that this list is
valid and that when the object destruction is done, this is free'd.

Commit cabcad185 removed the call to cogl_set_source_color4ub() before
cogl_fill_path(), so instead of the previously assigned selection color,

the correct color, switch from cogl_fill_path() to the (deprecated!)
cogl_framebuffer_fill_path() method.

4faeb12731 clutter/stage-cogl: Reschedule update on present
If an update (new frame) had been scheduled already before
`_clutter_stage_cogl_presented` was called then that means it was
scheduled for the wrong time. Because the `last_presentation_time` has
changed since then. And using an `update_time` based on an outdated
presentation time results in scheduling frames too early, filling the
buffer queue (triple buffering or worse) and high visual latency.

So if we do receive a presentation event when an update is already
scheduled, remember to reschedule the update based on the newer
`last_presentation_time`. This way we avoid overfilling the buffer queue
and limit ourselves to double buffering for less visible lag.

45244852ac clutter/stage-cogl: Don't skip over the next frame
The `last_presentation_time` is usually a little in the past (although
sometimes in the future depending on the driver). When it's over 2ms
(`sync_delay`) in the past that would trigger the while loop to count up so
that the next `update_time` is in the future.

The problem with that is for common values of `last_presentation_time`
which are only a few milliseconds ago, incrementing `update_time` by
`refresh_interval` also means counting past the next physical frame that
we haven't rendered yet. And so mutter would skip that frame.

**Example**

Given:
```
  last_presentation_time = now - 3ms
  sync_delay = 2ms
  refresh_interval = 16ms
  next_presentation_time = last_presentation_time + refresh_interval
                         = now + 13ms

          -3ms now        +13ms           +29ms           +45ms
        ----|--+------------|---------------|---------------|----
            :               :
  last_presentation_time  next_presentation_time
```

Old algorithm:
```
  update_time = last_presentation_time + sync_delay
              = now - 1ms
  while (update_time < now)
        (now - 1ms   < now)
    update_time = now - 1ms + 16ms
  update_time = now + 15ms
  next_presentation_time = now + 13ms
  available_render_time = next_presentation_time - max(now, update_time)
                        = (now + 13ms) - (now + 15ms)
                        = -2ms  so the next frame will be skipped.

          -3ms now        +13ms           +29ms           +45ms
        ----|--+------------|-+-------------|---------------|----
            :               : :
            :               : update_time (too late)
            :               :
  last_presentation_time  next_presentation_time (a missed frame)

```

New algorithm:
```
  min_render_time_allowed = refresh_interval / 2
                          = 8ms
  max_render_time_allowed = refresh_interval - sync_delay
                          = 14ms
  target_presentation_time = last_presentation_time + refresh_interval
                           = now - 3ms + 16ms
                           = now + 13ms
  while (target_presentation_time - min_render_time_allowed < now)
        (now + 13ms - 8ms < now)
        (5ms < 0ms)
    # loop is never entered
  update_time = target_presentation_time - max_render_time_allowed
              = now + 13ms - 14ms
              = now - 1ms
  next_presentation_time = now + 13ms
  available_render_time = next_presentation_time - max(now, update_time)
                        = (now + 13ms) - now
                        = 13ms  which is plenty of render time.

          -3ms now        +13ms           +29ms           +45ms
        ----|-++------------|---------------|---------------|----
            : :             :
            : update_time   :
            :               :
  last_presentation_time  next_presentation_time
```

The reason nobody noticed these missed frames very often was because
mutter has some accidental workarounds built-in:

 * Prior to 3.32, the offending code was only reachable in Xorg sessions.
   It was never reached in Wayland sessions because it hadn't been
   implemented yet (till e9e4b2b72).

 * Even though Wayland support is now implemented the native backend
   provides a `last_presentation_time` much faster than Xorg sessions
   (being in the same process) and so is less likely to spuriously enter
   the while loop to miss a frame.

 * For Xorg sessions we are accidentally triple buffering (#334). This
   is a good way to avoid the missed frames, but is also an accident.

 * `sync_delay` is presently just high enough (2ms by coincidence is very
   close to common values of `now - last_presentation_time`) to push the
   `update_time` into the future in some cases, which avoids entering the
   while loop. This is why the same missed frames problem was also noticed
   when experimenting with `sync_delay = 0`.

v2: adjust variable names and code style.

706c5a7565 clutter: LEQUAL depth_testing on ClutterDeformEffect
Moving an actor with a ClutterDeformEffect applied flickers because
the depth_testing, setting the depth testing test function to
COGL_DEPTH_TEST_FUNCTION_LEQUAL fixes the problem.

24b3467584 clutter: Send touch crossing events only to grab actor
When the pointer is grabbed, we send the crossing events that are
initiated by this pointer only to the actor that has the grab. For
grabbed touch sequences, we always capture and bubble the crossing
events right now.

Fix this and make grabbed pointers and touch sequences behave the same
by sending touch crossing events only to the grab actor.

9e0e35d2a7 clutter/click-action: Handle touch cancel events
It's important to cancel click actions when we get a touch cancel event,
otherwise the long press event might get emitted after the compositor
took over the touches because it detected a gesture.

63c40a9711 meson: Define srcdir and builddir using meson functions
No need to redefine paths starting from top src/build dirs, as meson can give us
this information for free using its functions.

a934fa07b8 tests: Use suites for test cases
They allows to filter tests better and so we can just launch tests with:
  meson test --suite [core|cogl|clutter] [single-test-name]

ba8f5a1178 clutter: Use g_signal_handler_disconnect to disconnect frequent signal
Clutter does the nicety of connecting just created PangoContexts to
ClutterBackend signals in order to update it on resolution/font changes.
However the way the signals are disconnected (automatically via
g_signal_connect_object() auto-disconnect feature) may incur into
performance issues with a high enough number of ClutterActors with a
PangoContext (eg. ClutterText) as the lookup by closure is linear across
all signals and handlers.

Keep the handler IDs around, and disconnect them specifically on dispose
so it is more O(1)-ish.
