There is no way to set any gamma luts, or do anything other color
management related. Eventually we'll probably want to, but that requires
bringing color management plumbing to PipeWire.
Doing this is also needed when running a headless session, as when
headless, polkit doesn't let us create colord devices without explicit
user permission, meaning we'll spam the session with useless dialogs
each time a session is started.

Given destruction order, the display goes away before the stage, so
this lingering signal connection may trigger unintended crashes.

`count_mode_setting_devices` was incorrect in both name and in function.
What it was actually doing was counting GPUs that had been registered with
the backend so far (during the `init_gpus` loop). What it was intended to
do was to count the number of `MetaRenderDeviceEglStream` instances, which
is the thing we're limited to only one of. So `count_mode_setting_devices`
would return zero whenever the first GPU initialized happened to be a
`MetaRenderDeviceEglStream`, which would in turn prevent
`MetaRenderDeviceEglStream` from successfully initializing. Seems it only
ever worked in the case of a hybrid system where the first GPU initialized
was GBM-based.
Now we count `MetaRenderDeviceEglStream` instances (zero or one) externally.
This allows initialization to succeed when it happens to be the first (or
only) GPU. And so `MUTTER_DEBUG_FORCE_EGL_STREAM=1` now works.

For scanout on a secondary GPU, for the time being try only formats
which are guaranteed to be renderable with GLES3, which notably excludes
10 bpc formats without alpha channel.
v2:
* Use separate format array for 10 bpc formats without alpha.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3139>
If the EGL_KHR_no_config_context extension is supported, use it to
choose a format per onscreen which is compatible with the scanout CRTC
and the GL rendering API used.
Suggested by Jonas Ådahl.
v2:
* Drop code which checked for GLES3 renderability. Makes no sense for
various reasons, in particular that EGLconfigs are about EGLSurfaces,
whereas secondary GPU contexts use an FBO for blitting.
* Use error parameter directly for meta_renderer_native_choose_gbm_format
call (Jonas Ådahl)

Preparation for the following commits, no functional change intended.
v2:
* Pass through MetaEgl pointer
v3:
* Make it return gboolean (Robert Mader)
v4:
* Add debug logging and corresponding purpose parameter
v5:
* Fix excessive function parameter indentation (Jonas Ådahl)

If the EGL_KHR_no_config_context extension is supported, pass
EGL_NO_CONFIG_KHR to eglCreateContext. This will allow binding the
context to surfaces created with different configs.

Split the struct into mutable and immutable parts. Access the mutable
parts via getters and the immutable parts via a single struct. This
avoids copying around the immutable parts.

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.

Now that the monitor screencast records to DMA-BUF buffers immediately
(since bc2f1145d8), and we know which phase of the paint rountines we
are (since last commit), we have the opportunity to bring back the
blitting technique.
Bring back blitting. This time, instead of simply failing if the blit
fails, add a fallback path that does a stage paint if something goes
wrong. Unlike the previous implementation of blitting, this one only
blits the current view - it does not blit all views that intersect
with the screencasted monitor.
Embedded cursors should still be fine because hardware cursor is
inhibited while embedded cursor screencasts are running.

Track where we are in terms of the paint cycle. Do this through an
enumeration that is passed through the paint vfuncs of screencast
sources.
Right now, this information is not used by any one of the sources,
but next patch will use it to prevent blitting when detached from
the paint cycle.

NULL actor pointers seem to arise sometimes in `clutter_stage_update_device`
when using a touchscreen, but that's only fatal with `CLUTTER_DEBUG=event`.
So just handle NULL where it was crashing: `_clutter_actor_get_debug_name`.

With the existing ClutterInputMode terminology (inherited from XI2),
hardware devices may be "physical" (i.e. attached to a logical device),
or "floating" (i.e. detached from all logical devices).
In the native backend, tablet devices are closer to "floating" than
"physical", since they do not emit events relative to the ClutterSeat
pointer logical device, nor drive the MetaCursorTracker sprite. This
is in contrast to X11 where all tablet devices drive the Virtual
Core Pointer by default, along with every other pointing device.
Change this mode in the Wayland backend to be more coherent. The
existing checks on the ClutterInputMode along Mutter seem appropriate
for handling these as floating devices, since they mainly care about
logical vs non-logical.

The window actor can be mapped every frame, e.g. when it is dragged in
the overview. This commit keeps track when the geometry changed and we
didn't managed to sync the geometry yet and need to sync it at a later
time.

At the end of the sync_actor_geometry function the window buffer_rect
and the WindowActor position and size are the same and consistent.
Call the virtual method at the end and let the implementations look at
either the buffer_rect or the actor position/size itself.

In some cases the window is not mapped when the geometry changes.
Without the mapped window the surfaces are not mapped either and don't
have a sensible allocation.
This patch makes sure we abort syncing the geometry if the window is not
mapped and also make sure we sync geometry when the actor eventually
does get mapped.

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.
