mutter-clutter is a private library that is only used by the shell and
not meant to be ABI/API compatible in between versions, so there's no
need to add padding to classes.

Hides libdisplay-info under a build time default-off flag,

We are attempting to show windows that do not yet have a
surface/buffer, this makes GNOME Shell avoid transitions
for these windows.
Since on Wayland X11 windows are also Wayland surfaces,
this check is also valid for these, and is thus made more
generic to also cater for these windows.
Eventually, meta_window_update_visibility() is called
when the surface gets its buffer, so the window can be
neatly animated.

Going for the default GL renderer is known to trigger rendering
artifacts using the NVidia proprietary driver. Since we don't have

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.

Enabling modifiers can help with app development. An example is

This function gets called when a surface state transaction is applied.
Applying a transaction can get delayed, so the Wayland resource may have

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.

It will be used to schedule Wayland frame events independently from both
update and presentation time, as the former may happen multiple times
frame and the later not at all.
For frame events we want a timing that is just late enough to ensure
that a following commit by a Wayland client will not get included into
the current frame any more.

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.

create_and_send_dnd_offer() sets the compositor of the offer to the one

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.

We might end up trying to apply a pending state late if it was delayed
by DMA buffers not being ready. Trying to discard the pending state from
the transaction when dismissing is hard, because we might be applying a
chain of transactions that would disqualify subsequent transactions if a
former one dismisses the popup, so lets just drop what the apply would
otherwise do, if we're not going to use it anyway.

If the popup was dismissed (i.e. has no MetaWindow anymore), it'll also

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.

When a stream source subclass asks for a DMA-BUF only frame record,
it is legitimate to return FALSE in do_record_frame() - meaning that
a frame was not recorded - but not return an error - meaning nothing
