The value returned from clutter_frame_get_target_presentation_time()
is always same as the value returned from
clutter_frame_get_min_render_time_allowed() when they are called
consecutively because both functions effectively return the value of
frame->has_target_presentation_time. This is with the assumption
that this variable is only ever modified by the same thread that
also executes on_after_update().
As such, a case where the former returns FALSE after the latter
returned TRUE is not possible, which means the line that sets
"target_presentation_time_us = 0;" is effectively unreachable.
Acknowledging this fact allows the call to
clutter_frame_get_target_presentation_time() to be moved outside the
"else" case and into the "if" condition itself. This is done in
preparation for the next commits.
No change in behavior.

In various public APIs, Clutter used to return a PangoDirection
while we have a text direction enum defined in Clutter.
This allows us to drop pango dependency from meta making it specific
to cogl-pango & clutter

It adds the following clarification:
```
Starting from version 5, the invalid_format protocol error is sent if
all planes don't use the same modifier.
```
We already send an error, just the wrong one.

Set the deadline timer state as "inhibited" in case a permission error
is returned while attempting to arm the deadline timer. This makes each
device enable its deadline timer again after a VT switch.
Also print a note in this case instead of a warning as such errors are
expected during a VT switch and should not raise concerns.

For now, this function only enables the deadline timer in case it was
inhibited. This would result in an attempt to use the deadline timer
again after a device is resumed.
If the conditions that resulted in the timer becoming inhibited
remain, it is expected to return to this state after the next frame
and before being armed.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3534>
The "disabled" state indicates that the deadline timer is disabled
for the lifetime of the device, while the "inhibited" state indicates
that it is disabled temporarily for the device.
This distinction is needed to handle each state differently in a
following commit. For now, only "disabled" is used.
No change in behavior.

This allows GNOME Shell to communicate the user desired XKB model
to the compositor instead of sticking with the pc105 default.
Particularly useful for those with a custom keyboard layout/irregular
keyboards.

Transient dialogs are meant to be placed centered over their
parent. However as we don't use the DIALOG window type on
wayland, this currently only works for modal dialogs.
To fix this, also apply the policy to NORMAL windows for
wayland clients.

Some panels only support fixed resolutions and fixed refresh rate with reduced blanking:
Established Timings I & II: none
Standard Timings: none
Detailed Timing Descriptors:
DTD 1: 2560x1600 120.001823 Hz 8:5 203.283 kHz 552.930000 MHz (345 mm x 215 mm)
Hfront 48 Hsync 32 Hback 80 Hpol P
Vfront 3 Vsync 6 Vback 85 Vpol N
DTD 2: 2560x1600 48.000295 Hz 8:5 81.312 kHz 221.170000 MHz (345 mm x 215 mm)
Hfront 48 Hsync 32 Hback 80 Hpol P
Vfront 3 Vsync 6 Vback 85 Vpol N
...
Minimum Pixel Clock: 552922 kHz
Maximum Pixel Clock: 552922 kHz
When using mirror mode, resolutions like 2560x1440 120Hz can be too high
to meet the pixelclock limitation, so 2560x1440 90Hz is selected
instead. However, the panel only supports 120Hz so using 90Hz result to
failed mode set.
So add reduced blanking to fallback mode, so correct refresh rate can be
used.

Since StDrawingArea in gnome-shell is the only user of ClutterCanvas,
it is possible to move ClutterCanvas completely out of Mutter to
gnome-shell. This allows to remove another Cairo dependency from
Mutter.
This patch removes ClutterCanvas code from Mutter.

COGL_DEBUG_ENABLED is a macro to check if a debug flag is set.
COGL_ENABLE_DEBUG is set by the build system if it's a debug build. The
check `#ifdef COGL_DEBUG_ENABLED` always evaluates to true. Use the
appropriate macro to guard some debugging code.

it is possible to move ClutterCanvas completely out of Mutter to

This patch makes clutter_actor_create_texture_paint_node() function
public to be used by StDrawingArea in gnome-shell that replaces

To paraphrase jadahl: we have a dedicated KMS thread now, which also
has realtime scheduling enabled unconditionally. realtime scheduling
on the main thread isn't too great of an idea, considering GC can
take a hot minute.
And to quote rmader: we most likely won't be able to make the main
thread rt as long as we use GJS and thus have GC.
So let's get rid of it! It's just been breaking things anyways.
This just ignores the setting; we'll fully remove it when GNOME 46
comes around.

This is the unified focus (key, IM, pads, ...) for the focus window.
Just like MetaWaylandPointer and others keep track of the "current"
surface, this is the "current" surface for those (not necessarily
the focused surface, e.g. in the case of compositor grabs).
Since this unified focus will exist regardless of keyboard
capabilities (e.g. even if just for "logical" focus like IM/clipboard
that does not depend on input devices), it does not make sense
to trigger a focus sync on keyboard capability changes, the focus
is staying the same, we however need to focus the keyboard interface
to the already existing focus when the capability is enabled.

Instead of letting the MetaDisplay be aware of the Wayland compositor,
and take care of updating its focus. This makes the MetaWaylandCompositor
able to track focus changes by itself, using MetaDisplay as the source
of truth.
