The debug controller can optionally, when passing --debug-control,
enable manipulating debug state, so far enabling/disabling HDR, via
D-Bus.
It's always created, in order to have a place to store debug state and
emit signals etc when it changes, but so far, it doesn't have its own
state it tracks, it just mirrors that of the monitor manager.

In profilers with a timeline or flame graph views it is a very common
scenario that a span name must be displayed in an area too short to fit
it. In this case, profilers may implement automatic shortening to show
the most important part of the span name in the available area. This
makes it easier to tell what's going on without having to zoom all the
way in.
The current trace span names in Mutter don't really follow any system
and cannot really be shortened automatically.
The Tracy profiler shortens with C++ in mind. Consider an example C++
name:
SomeNamespace::SomeClass::some_method(args)
The method name is the most important part, and the arguments with the
class name will be cut if necessary in the order of importance.
This logic makes sence for other languages too, like Rust. I can see it
being implemented in other profilers like Sysprof, since it's generally
useful.
Hence, this commit adjusts our trace names to look like C++ and arrange
the parts of the name in the respective order of importance.

Scoped traces are less error prone, and they can still be ended
prematurely if needed (this commit makes that work). The only case this
doesn't support is starting a trace inside a scope but ending outside,
but this is pretty unusual, plus we have anchored traces for a limited
variation of that.

meta_display_ping_window() does nothing when check-alive-timeout is set
to 0, but meta_window_check_alive_on_event() was relying on it to reset
the events_during_ping. Without this events_during_ping was just
counting up until the threshold was reached and the window was marked as
not alive, preventing further pointer events from being sent to the
window.
Fix this by not doing anything in meta_window_check_alive_on_event() if
check-alive-timeout is 0, similar to meta_display_ping_window().

Assigning the corresponding stack layer of DESKTOP windows is
currently X11 specific, because there is no way for wayland

This is about to change, so move the code to the generic layer

Focus follows mouse is meant to avoid focusing windows that happened
to pop up under the pointer, e.g. due to mapping, workspace changes,
etc... On X11, this has been done since ancient times through a
moderately complex synchronization mechanism, so mutter would know
to ignore crossing events caused on those situations.
This mechanism is much prior to XInput 2 though, where we may know
this in a more straightforward way: If the sourceid of the crossing
event is a logical pointer (i.e. equals deviceid), the crossing event
was triggered logically, and not through user input.
Perform this simpler check, and drop the existing mechanism to
ignore logically induced crossing events.

After an event has been handled such that it bypasses both Clutter and
Wayland, e.g. when handling a keybinding, bypass_clutter would get
unset in the presence of a wayland grab. This means that the event is
handled both as a keybinding and by Clutter.
In the case of switcher popups in gnome-shell in the presence of a gtk4
autohide popover this meant that instead of selecting the next element,
it would select the one after that. If there are only two elements, as
is common with input sources, this would mean going back to the current
one, preventing switching them with a single press of the keybinding.

Commit 3bfcb6d1 fixed the check for tiling via keybindings, but
ignored a subtle edge case when tiling with the pointer: The
monitor used for tiling is the monitor with the pointer, which
is not necessarily the one that contains the largest part of the
window.
That is, the correct monitor to check against depends on the
context where the function is called. We can either figure
it out automatically via the current window drag, or make it
a parameter.
The latter is clearer, because the callers already decide which
monitor to use for tiling anyway.

Use work area from the monitor that the window is currently on to
determine if tiling should be allowed.
Window tiling is disabled for monitors with portrait orientation, but
the work area we use to detect portrait orientation is taken from the
monitor that currently has the mouse pointer.
This works fine for edge tiling using the mouse, but this is broken when
using keybindings for window tiling because your mouse pointer could be
on a different monitor that has horizontal orientation.

Under strange timings, the GTK frames client may implicitly queue
relayouts that end up disagreeing with the latest frame size as
given by Mutter, this results in GTK calling XResizeWindow, and
Mutter plain out ignoring the resulting XConfigureRequestEvent
received.
This however makes GTK think there's pending resize operations,
so at the next resize it will freeze the window, until enough
resizes happened to thaw it again. This is seen as temporary
loss of frame-sync ness (e.g. frozen frame, and other weird
behavior).
In order to make GTK happy and balanced, reply to this
XConfigureRequest, even if just to ignore it in a more polite
way (we simply re-apply the size Mutter thinks the frame should
have, not GTK), this results in the right amount of
ConfigureNotify received on the frames client side, and the
surface to be thawed more timely, while enforcing the size as
managed by Mutter.

The 'suspend state' is meant to track whether a window is likely to be
visible any time soon. The hueristics for this are as follows:
* If a window is hidden, it will enter the 'hidden' state.
* If a window is visible, and unobscured, it will enter the 'active'
state.
* If a window is visible, but obscured by another window, it will enter
the 'hidden' state.
* If there is a mapped clone of a window, it will enter the 'active'
state.
* If the window has been in the 'hidden' state for 3 seconds, it will
enter the 'suspended' state.
This will eventually be communicated to Wayland clients so that they can
change their behaviour to e.g. save power.

This adds the actual input capturing rerouting that takes events and
first hands them to the input capture session, would it be active.
Events are right now not actually processed in any way, but will
eventually be passed to a libei client using libeis.
A key binding for allowing cancelling the capture session is added
(defaults to <Super><Shift>Escape) to avoid getting stuck in case the client
doesn't even terminate the session.

With window_is_terminal gone, "strict" and "smart" focus mode have no

As noted in the comments of window_is_terminal, this is a hack. This
code has not been touched for the better part of a decade. App res_class
tends to differ between Wayland and X11, so it is likely that none of
these apps have been recognised as terminals under Wayland ever. Also,
there are reports that strict focus mode also does not work under X11,
likely due to changes in these terminal apps over the years resulting
in different res_class than those manually specified in here. Let's remove
this hack and change strict focus mode accordingly.

Current behavior pushes a window which receives focus to the start of
the MRU list on every workspace it is on. By focusing a sticky window
the default focus on all other workspaces changes as well. This is fine
for sticky windows explicitly marked as sticky by the user but if a
window is on a secondary output and workspaces are only on the primary
output the behavior is unexpected. Instead we want the window to be the
default focus only on the current workspace but also keep those windows
in a relative MRU order to each other on all workspaces.

We need to juggle with some things here to keep key event ordering
and accounting consistent.
The keyboard internal state changes (and maybe modifier event emission)
happening through meta_wayland_seat_update() should ideally happen
from the same key events that reach the client through wl_keyboard.key,
so that wl_keyboard.modifier events are emitted in the right relative
order to other key events.
In order to fix this, we need to decide at an earlier point whether
the event will get processed through IM (and maybe be reinjected),
thus ignored in wait of IM-postprocessed events.
This means we pay less attention to whether events are first-hand
hardware events for some things and go with the event that does
eventually reach to us (hardware or IM).

When the X11 display is actually XWayland there's no point to delay the
compositor selection, given that mutter itself is the compositor and
doing this may cause the first X11 client that starts not to receive the
right information (and in some cases misbehave).
Since some toolkits are not handling the compositor selection changes
properly at later times, let's make their life easier by just
initializing the selection as early as the other X11 properties, given
that in this case there's nothing to replace.

Since on Wayland X11 windows are also Wayland surfaces,

When selecting the default focus window, is_focusable() was not
considering the new conditions for whether a window should be shown or
hidden that were added to meta_window_should_be_showing() in 39942974.
As a result the default focus window could end up a window already
hidden or hidden once meta_window_flush_calc_showing() is called by
meta_window_focus() when focusing the default window. This would cause
meta_window_focus() to fail, which is an issue if it prevents us from
unfocusing a window when it is getting unmanaged.

With the frames client, we do no longer handle events for the

With the move away from GTK3, and the indirect dependency on GTK4
grown in the GNOME Shell side, we've indirectly gotten a small sneaky
behavioral change: The GTK4 library will, right on dlopen, get
DESKTOP_AUTOSTART_ID for itself and delete it from the environment.
This happens before our own X11 session management code is
initialized, which confuses the hell out of it, into thinking
initialization is actually shutdown, gnome-session does not follow
along with this request, which leaves GNOME Shell into a confused
startup state where it never calls SmcSaveYourselfDone() and grinds
startup to a halt until gnome-session decides to move things forward.
In order to fix this, get the DESKTOP_AUTOSTART_ID before we lend
control to GNOME Shell bits and GTK4 is possibly initialized, and
feed it directly to our X11 session manager bits.

In order to make things more and more asynchronus and to each time we
paint be an isolated event, that can be potentially be applied
individually or together with other updates, make it so that each time
we draw, we use the transient MetaFrameNative (ClutterFrame) instance to
carry a KMS update for us.
For this to work, we also need to restructure how we apply mode sets.
Previously we'd amend the same KMS update each frame during mode set,
then after the last CRTC was composited, we'd apply the update that
contained updates for all CRTC.
Now each CRTC has its own KMS update, and instead we put them in a per
device table, and whenever we finished painting, we'll merge the new
update into any existing one, and then finally once all CRTCs have been
composited, we'll apply an update that contains all the mode sets for all
relevant CRTCs on a device.
