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.

When stage views are scaled with fractional scales, the cursor rectangle
won't be aligned with the physical pixel grid, making it potentially
blurry when positioned in between physical pixels. This can be avoided
by aligning the drawn rectangle to the physical pixel grid of the stage
view the cursor is located on.

Attaching a NULL buffer should hide the cursor sprite. In these cases,
we we'll have neither surface nor buffer damage, so also update when we
just attached a NULL buffer.
Fixes: https://gitlab.gnome.org/GNOME/mutter/issues/630
When 252e64a0ea moved the texture
ownership to MetaWaylandSurface, it failed to handle the case when a
NULL-buffer is attached, leaving the texture reference in place. This
caused issues when the surface should have been hidden (e.g. attaching a
NULL buffer to a cursor surface for hiding the cursor sprite).

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.

Starting from commit 7713006f5, during X11 disposition we also unmanage the
windows using the xids hash table values list.
However, this is also populated by the X11 Meta barrier implementation and then
contains both Windows and Barriers.
So when going through the values list, check whether we're handling a window or
a barrier and based on that, unmanage or destroy it.

As per commit 7718e67f, destroying the compositor causes destroying window
actors and this leads to stack changes, but at this point the stack was already
disposed and cleared.
So, clear the stack when any component that could use it (compositor, and X11)
has already been destroyed.
As consequence, also the stamps should be destroyed at later point.

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.

Naming the keyboard accessibility settings `a11y_settings` wrongly
assumes there will never be any other type of accessibility settings.
Rename `a11y_settings` to `keyboard_a11y_settings` to avoid future
confusion.
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.

To emulate X11 grabs, mutter as a Wayland compositor would disable its
own keyboard shortcuts and when the X11 window is an override redirect
window (which never receives focus), it also forces keyboard focus onto
that X11 O-R window so that all keyboard events are routed to the
window, just like an X11 server would.
But that's a bit of a “all-or-nothing” approach which prevents
applications that would legitimately grab the keyboard under X11 (like
virtual machine viewers) to work by default.
Change “xwayland-allow-grabs” to control whether the keyboard focus
should be locked onto override redirect windows in case of an X11 grab.
For stringent needs, careful users can still use the blacklisting
feature (i.e. a list containing “!*”) to prevent grabs from any X11
applications to affect other Wayland native applications.

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`.

MetaProfiler is not built when -Dprofiler=false, and that
breaks the build since MetaBackend unconditionally imports
and uses it.
Fix that by wrapping MetaProfiler in compile-time checks.

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.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/197
Add the ability to add tracing instrumentation to the code. When
enabled, trace entries will generate a file with timing information
that will be processable by sysprof for generating visualization of
traces over time.
While enabled by default at compile time, it is possible to disable the
expansion of the macros completely by passing --disable-tracing to
./configure.
Tracing is so far only actually done if actually enabled on explicitly
specified threads.
This will be used by Mutter passing the write end of a pipe, where the
read end is sent to Sysprof itself via the D-Bus method 'Capture()'.
By passing that, we have to detect EPIPE that is sent when Sysprof stops
recording. Fortunately, we already ignore the signal at meta_init(), so
no need to add a custom signal handler.
