5eb17a362e tests: Avoid CSD window in test
This ATM triggers missed .commit events for the window in question,
to be addressed in Xwayland. Since the test does not seem to specifically
rely on this window being CSD, make it a regular window instead.

57fdd7efd2 frames: Use cairo renderer on GTK frames
Going for the default GL renderer is known to trigger rendering
artifacts using the NVidia proprietary driver. Since we don't have
too many expectatives about frames being flashy (not to the point
of mandating GL), resort to the cairo renderer in the mean time.

cca07612b8 output: Check the EDID for the supported sink Colorimetry
Just like the HDR Metadata property the Colorspace property values only
indicate that the display driver supports signaling certain colorimetry.
It does not indidcate that the sink actually supports processing the
colorimetry. For this we have to look up the colorimetry support in the
EDID.

The default colorimetry is always supported. If we want bt.2020 we might
get either the RGB or YCC variant even if we ask for the RGB variant but
there is nothing we can do about it so let's just pretend it's a driver
issue.

754a1a1ce6 wayland/dma-buf: Enable modifiers by default on non-native backend
If the used EGL backend supports it. In practice this should currently
only affect the nested backend.

Enabling modifiers can help with app development. An example is
`weston-simple-dmabuf-v4l`, which requires the linear modifier to be
available.

Note that Weston behaves similar already.

a7a7933e03 wayland: Emit frame events in GSource after "empty" updates
Under certain conditions a stage-view update does not trigger a kms
update.

In such cases we still want the next update to run within the same
refresh cycle, as otherwise we'd waste the remaining time in the
current one.
At the same time we currently use the `after-update` signal for Wayland
frame events, which again may result in more "empty" updates -
creating an unthrottled feedback loop. This can trigger excessive
load both in the compositor as well as in clients.

Introduce a new GSource that is dispatched once per refresh cycle at
maximum per stage view and use it to emit frame events. Do so by
computing the time from when on we can be sure that an update resulting
from a client commit would certainly get scheduled to the next refresh
cycle.

Note: this only works on the native backend. Given that chances are
small that we hit the corresponding issue on e.g. the nested backend,
stick to the previous behavior there for now.

6b57ab8975 workspace: Only consider windows that should be showing as focusable
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.

2a600ac98e frames: Forward _NET_WM_STATE during frame initialization
Ensure the frame window is created at the right fullscreen state
before showing it and assigning it to the client window.

A peculiarity of this property on frame windows is that it is
typically single-handedly updated from the Mutter side, in synchronization
with client window state. It can only differ during creation, since
GTK still likes to apply its own state.

Also, the only relevant property seems to be _NET_WM_STATE_FULLSCREEN,
since the others are less relevant to the role of the frames client,
and get applied to the MetaWindow as a whole, instead.

47b6e76578 xdg-shell: Early out of apply if dismissed

f744acefee core: Create passive button grab on topmost Window
With the frames client, we do no longer handle events for the
frame window inside Mutter. This means we do not get events
"for free" to handle focus on a just clicked frame window.
This results in a background window not ending up focused if
clicked on its frame.

In order to fix this, make the passive button grab extend to
the frame window if a window has one. This brings back
focus-on-click behavior, while treating windows further as
a unitary surface.

This change allows clipped redraws for offscreen. The net
effect of this change is to preserve the original redraw clip when
possible (rather than overwriting it with the full view redraw) in
the paint context.

This eventually helps in retrieving the fine grained updated regions of
the frame since last redraw and sending it to the pipewire client
(as shown in a subsquent CL).

018786dab8 output-xrandr: Don't treat 0 as invalid backlight value
Whether a value is in range depends on the backlight-min/max values,
and I didn't spot anything that excludes 0 as a valid lower limit
outright.

aa1eaa8120 output-xrandr: Consistently return -1 on error
Returning FALSE does not indicate an error, but a valid backlight
value of 0. Consumers expect a negative value to indicate no
backlight support, so return -1 in case of error, just like we
already do for invalid values.

Lest it fails. Try to recover from that and keep reading
the mimetypes present in the atom list.
