On big endian architectures the mapping of drm formats to cogl
formats is significantly trimmed compared to on little endian
architectures.
meta_wayland_init_shm tries a bunch of formats, including some
that just aren't mapped on e.g. s390x.
The code asserts the mapping will exist, however, leading to
crashes when Xwayland starts.
This commit makes failure to find a mapping non-fatal.

When multiple configure requests sent to the wayland client within a sort period, maximized windows may end up in wrong position and cover struts.

The gnome-shell magnifier listens to the `visibility-changed` signal
and calls meta_cursor_tracker_set_pointer_visible(false) when the
cursor became visible.
This leads to a reentrance in meta_cursor_tracker_set_pointer_visible()
and clutter_seat_uninhibit_unfocus() gets called twice, once from the
meta_cursor_tracker_set_pointer_visible(false) by the magnifier and then
the original meta_cursor_tracker_set_pointer_visible(true) continues,
after the first call has set is_showing to false again. This breaks the
inhibitor counting and the ability to use the cursor while using the

X11 server side focus changes, such as when a focus change was requested
by mutter for a globally active window, did not go through
meta_display_set_input_focus(), which is responsible for emitting the
`focus-window` signal. Since this signal is what triggers the display
server specific code to handle focus changes, this was leading to a
problem on Wayland where the focus remained on the last active Wayland
window when the focus got changed to a globally active XWayland window.
This commit now changes handling X11 server side focus changes to also
go through the code path that emits the signal while making sure to not
trigger another focus change and keeping the same serials as the
previous code to not interfere with future focus changes.

Note that if the surface is visible on multiple monitors with different
transforms, we pick the transform of the monitor which we choose for the
scale as well. This doesn't really matter at the moment, as the

Some clients - notably the Gstreamer vapostproc element when using Intel
GPUs - only support BGRA, not BGRx. We already assume that we can
support this format for window screen casts, and even in case of failure
we now have a re-negotiation fallback in place. Thus it's pretty safe to
support it for all screen cast types.
The possible duplication in case of window screen casts doesn't seem to
be a problem for either Pipewire or existing clients like OBS.
Note that the implementation lays the foundation to make it easy to add
more formats in the future.

The POINTER_EMULATED flag was a convenience to filter either
side of smooth/discrete events that we should ignore based on
the source.
This distinction was challenged, first by v120 mice that use
Clutter smooth events to deliver semi-discrete changes, second
by commit e0c4b2b241 ("backends/native: Mark the emulated smooth
scroll event as such") which made the smooth events be flagged
as emulated, and the discrete whole-step events marked as
real.
This distinction feels convenient for the time being, since
upper layers might be confused by real smooth scroll events
without finish flags. Adapt to this change at MetaWaylandPointer
so that we drop the POINTER_EMULATED check, and the events are
perhaps filtered based on their source and the preferred
wl_seat version of the client that we are talking to.
This handles the whole grid of combinations:
- wheel sources with wl_seat >=8 result in wl_pointer.axis_value120
from "emulated" smooth scroll events, with value120 information.
- wheel sources with wl_seat < 8 result in wl_pointer.axis_discrete
from "real" discrete scroll events.
- finger/continuous sources prefer smooth events. Previously, always
non-emulated for those.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3642>
The wl_pointer.axis_discrete axis (applicable to wl_seat <= v8) is
meant to be sent together with wl_pointer.axis events in the same
frame. And the wl_pointer.axis_value120 event replaces it in
wl_seat >= v9, but has the same relation with the other information
available in a frame.
This emission should not be conditional to anything, so drop the
various checks leading to maybe sending wl_pointer.axis or not.
This fixes emission of wl_pointer.axis in conjunction with discrete
events, for some combinations of versions and (non)value120 mice.

discrete events, as we don't send wl_pointer.axis_value120 for these.
Fix this by assigning a value120 value to discrete scroll events. This
makes wl_pointer.axis_value120 events actually sent on non-v120 mice.

meta_window_handle_ungrabbed_event() triggers the show of the window menu in
gnome-shell via meta_window_show_menu() on hold of Meta + right mouse button
click.
Since meta_display_handle_event() was refactored lately and now forwards a
lot more events to Clutter (including the one triggering the window menu),
gnome-shell now sees this event after the menu has opened, figures that the
source-actor is outside of the menu, and immediately closes the menu again.
This is the correct behavior from the PopupMenuManager on the gnome-shell
side, it is the responsibility of the event handler that opens the menu (aka
meta_window_handle_ungrabbed_event()) to return CLUTTER_EVENT_STOP and stop
event propagation.
So fix this issue by adding a return value to
meta_window_handle_ungrabbed_event() and stopping event propagation in case
the event opened the window menu.
While at it, also return CLUTTER_EVENT_STOP for events triggering window
drags, so we can drop the extra check for that in

priv->current_drag is the property that
meta_compositor_get_current_window_drag() and therefore also
meta_display_is_grabbed() bases its check on. We use
meta_display_is_grabbed() to select which cursor to use (window cursor
vs root cursor) when updating the cursor in MetaCursorTracker.
Since meta_window_drag_begin() sets a new cursor, and therefore triggers the
cursor tracker to update the current visible cursor, we should set
priv->current_drag before the call to meta_window_drag_begin(). This makes
sure the cursor tracker sees that there's a window drag and changes the
cursor right away when the window drag begins (instead of doing so on
subsequent pointer events).

Find a surface actor that meets the criteria to drive the refresh
rate for the view. If a new surface actor is found, add a
reference to it and request frame synchronization to be enabled
for the relevant MetaRendererViewNative.
Whenever the surface actor schedules a repaint or an update, and
in case frame synchronization is enabled for the
MetaRendererViewNative, schedule the update to occur "now". This
effectively makes the surface actor's frame rate drive the refresh
rate of the monitor.
If the actor is frozen or destroyed, it is no longer expected to
schedule repaints or updates and should stop driving the refresh
rate.
When there is no surface actor to drive the refresh rate, request
frame synchronization to be disabled for the MetaRendererViewNative.

This makes all stage updates that result from applying the pending
state of a Wayland surface emit an "update-scheduled" signal in the
context of the relevant surface actor.
A common case where an "update-scheduled" signal is needed is
when applying "empty" client commits. In this case a
"repaint-scheduled" signal would not be emitted since the commit
doesn't trigger a repaint. However, it is still important to add
handling for such updates with variable refresh rate when the
releavnt actor is also driving the refresh rate.

Use a sufficiently low refresh rate to calculate the CRTC deadline
when variable refresh rate is enabled. This is done to avoid cursor
updates from driving the monitor refresh rate.
It's not great solution and is sometimes not enough, but it avoids
stutter in the main content as a result of cursor movement in most
cases.
The unfortunate downside of this approach is that cursor movement
would usually only update with the main content and would not be
smooth when the main content updates are not frequent enough.
A better solution may use an approach similar to LFC (Low Framerate
Compensation) to insert cursor-only updates between updates of the
main content, but achieving adequate results with an approach of this
nature requires more research and experimentation.

Currently, we don't handle too well the removal of a MetaWaylandEventInterface
during meta_wayland_event_interface_invalidate_all_focus(), since the
MetaWaylandEventInterface may be freed at an intermediate point in that function
while handling the focus change for all input devices.
Turn this invalidate_all_focus() function into a MetaWaylandInput method, and
always ensure to use the currently effective MetaWaylandEventInterface when
resetting the focus for each device.
This fixes the situation through handling reentrancy naturally, a focus
sync (say, triggered by a grab) would reset a device focus (say, pointer), which
would remove an event interface (say, a pointer constraint), which would
invalidate_all_focus() again underneath using the new effective
MetaWaylandEventInterface. When that is done, the initial invalidate_all_focus()
call would re-apply the same focus to the same currently effective

Relying on the content size_allocate() to determine the content position
can fail in situations where the position of the content has changed,
but not its size.
This happens for example when the window initially is sized fullscreen
height + headerbar height while not considered fullscreen yet. Then when
the window is resized to just the fullscreen height and marked as
fullscreen, the content size has not changed and size_allocate() is not
called on the content. Thus the previous position which assumes the
presence of a headerbar still applies. As a result the window is shifted
down, revealing a headerbar sized area showing the gtk window background
color.
This issue can be avoided by using the frame's size_allocate(), which
gets called in response to all relevant events, such as any headerbar
size changes, headerbar visibility changes, window resizes and
fullscreen status changes.

Turns out there is a better solution: Almost always, MetaWindow already has
an idea on which monitor it will be, even if it isn't positioned yet. Since
the last commit we're now using that monitor for setting the
highest-output-scale of the window, so this fallback is no longer necessary.
While we could keep this fallback around and also return a valid scale in
case the surface is not even mapped yet, this means we report fractional
scale twice for new surfaces: Once from
wp_fractional_scale_manager::get_fractional_scale() (here we'll enter the
fallback), and a second time (this time with correct scale) right after
creating the MetaWindow.
Note that wp_fractional_scale_v1 doesn't specify that a preferred_scale
event must be sent immediately after
wp_fractional_scale_manager::get_fractional_scale(), so we can safely remove
the fallback.

MetaWindow always tries to have a main monitor: If the frame rect is empty
and the window has not been positioned, in meta_window_constructed() we fall
back to asking the backend for the current monitor, and in
meta_window_wayland_update_main_monitor() we fall back to
meta_window_find_monitor_from_id(), which then falls back to the primary
monitor.
In general this means that window->monitor is always set as long as there is
a monitor around.
For getting the highest-scale-monitor the window is on, we currently rely
completely on the frame rect. If the frame rect is empty, we set the
highest-scale-monitor to NULL. Since we usually know though which monitor
the window is, or will be on, and window->monitor is even set to that, we
can just fall back to window->monitor for the highest-scale-monitor.
This makes sure ::highest-scale-monitor-changed is emitted right after the
window is created, and it's set to the correct monitor that the window will
be on. This in turn means that we can send a correct wp_fractional_scale
fraction_scale event to clients right away.

synchronization is necessary before-update. Assuming both are correct
then it needs to be done in both places.
I did try optimizing out the second sync to only do it if damage
arrived during the update, but that doesn't seem to be the issue.
The damage event is arriving before the update starts and it's some
secondary changes within the damage region running late that need
flushing. So this means the client is reporting damage more frequently
than the frame rate and we're ignoring the secondary damage reports
for efficiency (XDamageReportBoundingBox), which is still a good thing.

This change adds modifier-aware screencasting support to Mutter.
Implicit modifier support is kept for backward compatibility and the
code fallbacks to implicit modifiers in case any new functionality added
for explicit modifier support fails.
The advertised modifiers are retrieved by a call to
eglQueryDmaBufModifiersEXT() function. The "external only" modifiers are
excluded as Mutter uses the buffers created with the explicit modifiers
as renderbuffers. Support for implicit modifiers is checked with a test
allocation since there are drivers that do not support them.
This change also removes various implicit modifier support checks that
disable DMA-BUF screen casting support globally as they are no longer
needed. DMA-BUF support for screencasting is determined by the available
formats and modifiers case-by-case now.
It also effectively enables DMA-BUF screencasting on NVIDIA hardware as
well since GBM buffer objects with linear modifiers are no longer used
by default to create a renderbuffer object for screencasting.

meta_render_device_gbm_allocate_dma_buf() function is updated to take a

Currently, we blindly apply the transformation matrices of all parent
actors when calculating the absolute coordinates. This means if this
function is called while the window actor containing the surface is in
the middle of a transition (e.g. window open animation), it may return
incorrect values. As this function is used for calculating pointer
confinement bounds for a specific surface, this will result in incorrect
bounds value being used if pointer constraints are applied by the
application at the same time the window is created and the mouse is
inside the surface's bounds when it's created.
Fix this by only applying transformation matrices up to the window actor
of the surface and then calculating the absolute coordinates by adding
the position of the window actor.

If we don't have a monitor for a surface - e.g. because the surface is
not mapped yet - return the highest scale of all outputs. This makes us
send a preferred scale before a client draws its first frame. The highest
scale is always correct in single monitor cases and arguably a good
option otherwise as scaling down usually looks better than scaling up.
Note that this is currently only used by the fractional scale protocol,
but will also be used for the core `send_preferred_scale()` once we
implement it.

With Wayland popups and drag-and-drop using grabs, we
should let window cursors prevail when there is one
in effect.
Also, resort always to the actor as known by the

gtk4-demo textview without motion would keep the I-beam
cursor, now results on the right actor/cursor for the

Enable grabbing input for popups, and drag-and-drop. Since the very
switch to using ClutterGrab underneath Wayland grabs will challenge
assumptions in existing code, these had to change in one go. A notable
one is that meta_display_windows_are_interactable() is not 100% true
anymore for xdg_popups, at least not the same.
Another change happening in lockstep is MetaDnD no longer having
to funnel events to Wayland, since the grab triggered by Wayland DnD
is now a cause of "compositor grabs", and will naturally receive events
as long as it hold. while "modal".
A number of ad-hoc checks for grabbing state has also been dropped
from src/wayland/ internals, since again Wayland grabs are a reason
for Clutter grabs, plus the mechanism itself will already take care
of focus loss and restoration.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3420>
Add the mechanism to integrate MetaWaylandEventInterface with grabs,
callers may now specify whether a grab is required, in which case
one is created, shared by all the event interface stack.
ClutterStage grab state is also tracked, so the MetaWaylandEventInterface
in charge will focus or unfocus depending on whether input should be
handled (if ungrabbed, or grabbed by the MetaWaylandInput itself), or
not (if grabbed by something else).
At the moment nothing uses this mechanism yet, later commits will add
the first users.

Now that the backend handles 0-size regions naturally and MetaWaylandPointer
avoids sending wl_pointer.motion on unchanged coordinates, we can use the
default motion handler for the locked pointer constraint.
And since that is the only difference with the pointer constraint event
interface, we can unify them both into a single MetaWaylandEventInterface
handling focus for them both.

The small catch is that MtkRegion (and pixman regions) "optimize away"
0-size rectangles, so a 0-sized region will always be seen as having
a 0,0 origin. We don't want that, so transfer the origin separately from
the region.
While at it, make the Wayland pointer lock use one such 0-size region,
to avoid the 1x1px wiggle room that it currently has (accounting for subpixel
motion).

While every kind of input is seen as coming from the Virtual
Core Pointer in the X11 case, we can largely abstract away from
that fact, and lock XDnD pointer input to the most plausible
source (e.g. a device with a pressed button), instead of only
working with pointer input.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3420>
This collection of event handlers is the most special of them all, as
they want to unset any pointer/touch/stylus/keyboard/pad/etc focus,
and handle events from a selected device/sequence combination through
the MetaWaylandDragDest interfaces.
The same interfaces also replace the MetaWaylandKeyboardGrabInterface
in effect that handled DnD action changes.
On the XDnD special grab side, we mainly need to let the current
client (i.e. the drag source) keep receiving input events, as they
drive the DnD operation from the X11 realm.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3420>
This is again a grab interface that mostly wants to meddle with focus,
logically setting a NULL surface if the surface client does not match
the popup client.
Since popups are meant to naturally work with any input device, the
code has been refactored to not involve the MetaWaylandPointer directly
in MetaWaylandPopup creation or getting the top popup surface (memory
management was shuffled), or compressing multiple grabbing xdg_popups
together (the existing grab maintains a single MetaWaylandEventHandler
for all).
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3420>
Besides the pointer locking/constraining mechanism, these grab interfaces
were more of a focus tracking mechanism, revoking the constraints when
the conditions didn't meet.
This can be handled pretty similarly to keyboard grabs with the new
interface, with the added bonus that we can chain up to let the
parent/default handler handle the events themselves, without poking at
MetaWaylandPointer API.

This is implemented at the MetaWaylandSeat level, and it governs

MetaWaylandInput is an object that will become in charge of handling
input events on their way to the Wayland socket. It keeps a stack
of event handlers, and propagates events and changes across them in
order to have them emit Wayland events, or change focus.
Each of these event handlers has a MetaWaylandEventInterface, this
is a vtable meant to replace MetaWaylandPointerGrabInterface and
MetaWaylandKeyboardGrabInterface in an unified manner, with the
following methods:
- get_focus_surface: to return the focus surface for a device/sequence.
Since several handlers will want to delegate logic on previous
handlers, it is optional to chain up with
meta_wayland_event_handler_chain_up_get_focus_surface().
- focus: To trigger a focus change for a device/sequence, since
event handlers are daisy chained by default, it is mandatory to
chain up with meta_wayland_event_handler_chain_up_focus(), either
with the given surface, or passing NULL to let later handlers
unset their state.
- press/motion/release: Unified handlers for pointer/touch/stylus
input, they chain up like event handlers do.
- key: Key event handler, propagates like event handlers do.
- other: Fallthrough for other events (pad, scroll, ...), propagates
like event handlers do.
Since there is a variety of expected behaviors, and the possibility
of stacking for some of the existing Wayland "grabs", this provides
the mechanism for that to happen.

That would be the surface under the tool that is being currently used

The MetaWaylandPointer used to put this together through
MetaCursorTracker cursor visibility, and ClutterSeat-level
inhibition API, applying the pointer focus changes due to
visibility logically to Wayland clients.
In order to make this work over all Clutter widgetry
instead of just Wayland clients, make the ClutterSeat-level
inhibition API control this feature at the ClutterStage picking
level, and leave/enter the seat pointer as appropriate.
By default, the seat pointer has (un)focus inhibited. The
MetaCursorTracker has been made another player in unfocus
inhibition, simply asking for the pointer to get its focus
while the cursor is visible.
This in practice means that picking code may return a NULL
actor, some asserts and preconditions had to be changed to
handle this, plus some test code slightly.

Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3177>
Until now we only supported direct scanout to the primary plane if the
buffer size perfectly matched the display size.
Since display controllers usually support scaling and cropping buffers
highly efficiently, try to let them do the job. This is usually helpful
if wp_viewporter is used by the client or Mutter uses fractional
scaling.
This has several advantages:
- Games (e.g. SDL2 based ones) can almost always hit direct scanout
paths in fullscreen mode. Notably when fractional scaling is used or
the game renders in a non-native resolution (or both).
- Video players using YUV buffer formats and wp_viewporter can easily
hit direct scanout paths, making displaying video very power
efficient as the 3D engine is not used at all.
Note that this still only uses the primary plane, no overlay or underlay
planes, making this change comparatively low risk.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3177>
In a following commit we will start supporting scaled and croped
surfaces, thus, in preparation, update the logic to three common cases:
1. only one surface, fullscreen (most apps)
2. a content surface and a black background surface which the client
does not want to unmap, fullscreen
3. top-level subsurface covers the whole window and is opaque (Firefox)
The remaining currently supported cases should be fairly uncommen and
and harder to compute.
Note that we already check that the window cover the stage view in
MetaCompositorView.

The code that maybe flushed IM state before processing a key event
became ineffective at commit 7716b62fa2, since the handle_event()

events and touch/button press events causing IM state to be
committed. Basically, the events that directly change the IM state.
Move this ineffective code to the the filter_event() method handling
the key presses in order to let the IM maybe filter them, and handle
them so that any key event that is let through (both key events
previously injected by the IM, and key events that the IM chooses to
ignore) will ensure that the pending IM state is flushed before the
key event is handled and emitted to the client.

When Wayland clients send commits without a buffer attached ("empty"
commits), they may lead to stage updates that do not result in any
frame being submitted for presentation ("empty" updates).
Due to how frame scheduling is handled, there can be many such
"empty" updates in a single refresh cycle. If frame callbacks were
emitted after each of these "empty" updates, and if the client
sending "empty" commits was using frame callbacks to throttle the
same logic that results in these "empty" commits being sent, it would
result in a feedback loop between Mutter and the client where the
client would send "empty" commits and Mutter would reply almost
immediately with a frame callback causing the client to send "empty"
commits continuously.
As such, when an "empty" update is detected, frame callbacks are
scheduled to be emitted only once in every refresh cycle, avoiding the
feedback loop.
When a "non-empty" update is detected, frame callbacks are instead
emitted immediately to allow clients to draw their next frame as soon
as possible. It is safe to emit frame callbacks in this case because
the frame for the current refresh cycle is already "finalized" and
that any commit sent by the client at that point would only be handled
in a future refresh cycle.
To implement this, the previous logic had used
meta_frame_native_had_kms_update() to detect "non-empty" updates,
assuming that those would always result in a KMS presentation with the
native backend.
However, this approach misses the fact that virtual monitors do not
use KMS, and as such do not result in KMS presentation even for
"non-empty" updates. As a result, frame callbacks would not be emitted
immediately, resulting in unintended throttling of client rendering.
Instead, assume that it is safe to emit frame callbacks immediately
whenever an update results in the frame clock waiting to be notified
of presentation, since this is also when commits sent by clients are
scheduled to be handled in a future refresh cycle.
This issue was mostly hidden because frame callbacks would be sent
immediately when the target presentation time for the frame had
changed compared to the previous frame. However, this behavior was
removed in 26d8b9c69 ("wayland: Remove unnecessary dispatch of frame
callback source"), exposing the issue.

The specifics of the deadline calculation for a given frame should be

To avoid communicating lower frame rate to clients through frame
callbacks, it is important to avoid delaying the source dispatch when
a dispatch is already scheduled.
To that end, the previous logic would emit pending frame callbacks
immediately in case a source dispatch was still scheduled for the
previous refresh cycle and then (potentially) schedule another source
dispatch for the current refresh cycle.
However, emitting pending frame callbacks immediately would send
frame events for every pending frame callback, including for the
current "empty" update. Scheduling another source dispatch for the
current cycle was then unnecessary and potentially undesirable
because there may not even be another "empty" update during the cycle.
Instead, let the already-scheduled source dispatch handle emitting any
pending frame callbacks, and do not schedule an additional source
dispatch for the current cycle as it may not be needed.
This approach is useful because it removes an implicit assumption
that the refresh rate is fixed and that target presentation time
remains constant within a refresh cycle. This assumption does not
apply for VRR.

The value returned from clutter_frame_get_target_presentation_time()
is always same as the value returned from

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

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

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.

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.

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.

If we happen to be changing focus to a window *while* taking focus
away from Clutter widgetry, we would unintendedly trigger reentrance
in a way that the old focused window remained in focus, by asking
to focus the default focus window in an untimely manner.
To handle this reentrancy, delay dropping the Clutter key focus
until the window focus changed, so that the focus change will look
up the default focused window in the workspace, and find the up to
date one.

Trying to get the xwindow of a wayland only window would fail when
casting to a x11 window. Which happens as
meta_x11_display_set_input_focus is called whenever the focused
window changes, whether it is a wayland or x11 one
