The type has been deprecated, so stop using it. The easiest replacement
would be to add our own struct, but considering that separate name/value
arrays are easier to free (g_auto!) and we already do the split in one
place, go that route.

Glib stopped providing any fallback implementations on systems without
memmove() all the way back in 2013. Since then, the symbol is a simple
macro around memmove(); use that function directly now that glib added
a deprecation warning.

Currently nothing in the clutter machinery prevents hidden portions
of the actor tree from calling queue_relayout() (and having it fully
honored).
But that allocation should not be necessary till the actor is shown,
and one of the things we do on show() is queueing a relayout/redraw
after flagging the actor as visible.
We can simply defer clutter_actor_allocate() calls till that show()
call, and leave the needs_allocate and other flags set so we ensure
the allocation is properly set then.
This should cut down some needless operations when invisible portions
of the actor tree change indirectly due to user interaction, or due
to background activity.

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 libwacom is configured disabled, this error appears:
../clutter/clutter/x11/clutter-input-device-xi2.c: In function ‘clutter_input_device_xi2_finalize’:

Fix it with the "obvious" solution.

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.
