Clutter has two motion event toggles: one in the global context, and
one per stage. The global one is deprecated, and currently unused.
Remove the global motion event handling.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/666
The “togglekeys” setting is to emit a sounds whenever the state of one
of the modifiers keys (CAPS lock, NUM Lock, SCROLL lock) is changed, it
has nothing to do with the rest of the accessibility settings.
Therefore, there is no need to reset the various timers used by
accessibility whenever the “togglekeys” setting is changed.

ClutterStage:after-paint now does not guarantee a valid
implicit framebuffer pushed to the stack. Instead, use
the new 'paint-view' signal, that is emitted at a point
in the drawing routine where a framebuffer is pushed.
In addition to that, stop using the implicit framebuffer
API and port the actor-shader-effect test to read from
the view's framebuffer directly.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/623
Now that ClutterStageView is embraced as part of the public
set of Clutter classes, is it possible to give consumers
of this API more information and control over the drawing
routines of ClutterStage.
Introduce ClutterStage:paint-view, a signal that is emitted
for painting a specific view. It's defined as a RUN_LAST
signal to give anyone connecting to it the ability to run
before the view is actually painted, or after (using the
G_CONNECT_AFTER flag, or g_signal_connect_after).
This signal has a corresponding class handler, which allows
Mutter to have much finer control over the painting routines.
In fact, this will allow us to implement a "paint phase watcher"
mechanism in the following patches.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/623
ClutterStage:after-paint is supposed to be emitted after all
painting is done, but before the frame is finished. However,
as it is right now, it is being emitted after each view is
painted -- on multi-monitor setups, after-frame is being
emitted multiple times.
Send after-paint only once, after all views are painted and
before finishing the frame.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/623
As a compositor toolkit, it makes sense to allow consumers
of Clutter interact with the stage views themselves. As such,
ClutterStageView should be a public class.
As such, it is now included in clutter.h and should not be
included directly.

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.

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.

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.
Closes: https://gitlab.gnome.org/GNOME/mutter/issues/406 and
https://bugzilla.gnome.org/show_bug.cgi?id=781835https://gitlab.gnome.org/GNOME/mutter/merge_requests/363
If `last_presentation_time` is zero (unsupported) or just very old
(system was idle) then we would like to avoid that triggering a large
number of loop interations. This will get us closer to the right answer
without iterating.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/363
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).
https://gitlab.gnome.org/GNOME/mutter/merge_requests/363
Instead of crazy refresh rates >1MHz falling back to 60Hz, just honour
them by rendering unthrottled (same as `sync_delay < 0`). Although I
wouldn't actually expect that path to ever be needed in reality, it just
ensures an infinite `while` loop never happens.

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.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/512
Pointer accessibility features requires to receive all pointer events
regardless of X11 grabs.
Add XI2 raw events mask and hook up the pointer accessibility handlers
to the raw motion and button press/release events.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/512
Add support for click assist, namely simulated secondary click (on a
long primary button press) and hover click support (simulate a click when
the pointer remains static for some time).
https://gitlab.gnome.org/GNOME/mutter/merge_requests/512
Add the required signaling in place in clutter device manager to notify
the upper layers (namely, the shell) whenever a click assist delay or
gesture is started or stopped.
This will allow the shell to implement a visual feedback for click
assist operations.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/512
For accessibility features, being either keyboard accessibility to
implement mousekeys, or pointer accessibility to implement simulated
secondary click or dwell click, we need to have a virtual device.
Add that virtual device in ClutterInputDevice so it can be used either
for keyboard or pointer accessibility.

Certain arguments like `-fno-omit-frame-pointer` break GIR creation.
Lets handle this like we do for the rest of mutter and duplicate the
relevant arguments from `clutter_c_args`.

Spotted while adding tracing to swap buffers, we only enter
the first part of the if condition when use_clipped_redraw
is TRUE, so it's pretty safe to assume it's TRUE.

The idea here is to be able to visualize and immediately
understand what is happening. Something like:
```
[ view1 ] [ view2 ]
[---- Layout ---][------ Paint ------][ Pick ]
[================== Update =====================]
```
But with colors. A few of the previous profiling data
sections were removed, since they didn't really add to
reading the graph.

Add debug flags based on meson's `debug` option instead of `buildtype`.
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

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 background is drawn with the last set source.
In order to honour the newly added framebuffer parameter and still apply
the correct color, switch from cogl_fill_path() to the (deprecated!)
cogl_framebuffer_fill_path() method.

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.

Pango functions pango_unichar_direction() and pango_find_base_dir() have been
deprecated in pango 1.44, since these are used mostly clutter and gtk, copy the
code from pango and use fribidi dependency explicitly.
This is the same strategy used by Gtk.
