It's pointless to call into functions that produce information that will
end up nowhere, so lets not. This will generate less angst when doing
more intense data gathering and string generation in debug log calls.

Fedora's mutter is built with --auto-features=enabled which enables
-initfd support. But the current meson code doesn't check whether
-initfd is available in Xwayland, leading to the wayland session not
starting up.
Check for -initfd's availability before enabling it.

The timestamp sent with _NET_WM_FRAME_DRAWN should be in "high
resolution X server timestamps", meaning they should have the same scope
as the built in X11 32 bit unsigned integer timestamps, i.e. overflow at
the same time.
This was not done correctly when mutter had determined the X server used
the monotonic clock, where it'd just forward the monotonic clock,
confusing any client using _NET_WM_FRAME_DRAWN and friends.
Fix this by 1) splitting the timestamp conversiot into an X11 case and a
display server case, where the display server case simply clamps the
monotonic clock, as it is assumed Xwayland is always usign the monotonic
clock, and 2) if we're a X11 compositing manager, if the X server is
using the monotonic clock, apply the same semantics as the display
server case and always just clamp, or if not, calculate the offset every
10 seconds, and offset the monotonic clock timestamp with the calculated
X server timestamp offset.
This fixes an issue that would occur if mutter (or rather GNOME Shell)
would have been started before a X11 timestamp overflow, after the
overflow happened. In this case, GTK3 clients would get unclamped
timestamps, and get very confused, resulting in frames queued several
weeks into the future.

Mutter sends a proximity-in event before the required tablet tool
resource is properly allocated on the client. This is violating the
Wayland protocol. Because libwayland ignores events for objects it
doesn't know yet, this is not noticeable in most applications. However,
if https://gitlab.freedesktop.org/wayland/wayland/-/issues/176 gets
fixed, these applications would likely crash immediately. Therefore this
PR removes the responsible code which, again, shouldn't have any effect
on client applications as they ignore this event anyway.
Relevant part of the spec:
This event can be received when the tool has moved from one surface to
another, or when the tool has come back into proximity above the
surface.

When we resize a window we send it configure requests with size
suggestion. Some clients, e.g. gnome-terminal will limit its size to a
discrete set given the font size resulting in the size often not being
respected completely, but used as a hint to find a size as large as
possible but not larger than the configured size.
When doing an interactive resize dragging the right or top side of a
window, this caused issues with the configured window size not matching
the one used by the client, as the configured position wouldn't be
correct for the actual size. Fix this by offsetting the position given
the size mismatch offset, making the position again in sync with the
size.

Keeping track of the projected position is costly, and adds quite some complexity
to ClutterOffscreenEffect.pre_paint(). As far as research goes, there's not a
single consumer of this function that uses the position for anything - only size
is used.
Remove clutter_offscreen_effect_get_target_rect(), and drop the annoying position
field from ClutterOffscreenEffect as well. This allows us to stop projecting the
position on pre-paint, and simplify things.

ClutterPipelineNode will be used by GNOME Shell in the future.
Fortunately for us, CoglPipeline is already usable from GJS,
so we don't need to skip the constructor for the pipeline node.

Move unreffing the framebuffer to ClutterOffscreenEffect.pre_paint().
This will allow us to properly chain up ClutterOffscreenEffect.paint()
and not reimplement exactly what ClutterEffect does by default.

Mutter still relies heavily on singletons such as its MetaBackend.
For that, the backend implementation has a meta_init_backend() function
which is called at startup from meta_init(), which creates the desired
backend and sets the singleton which is returned by meta_get_backend().
Unfortunately, that means that the backend is never actually freed, and
all the code from the backend finalize function never actually get
called.
Add a meta_release_backend() to free the backend singleton.

The input settings constructor installs callback functions on device
added/remove and tool-changed.
However, on dispose, those signals are not disconnected, meaning that on
teardown, once the devices get removed eventually, the callback will
still fire and call the callback with freed data, causing a crash.
Make sure we clear the signals on devices on dispose, to avoid the crash
on teardown.

A boring one, with the exception that row and column needed to be
swapped. For the sake of consistency, the variable names were also
synchronized with the values they hold, so e.g. xy → yx, etc.

This one is a bit tricky. The tl;dr; is that switching from right-hand
multiplication to left-hand multiplication required applying the stack
from left to root. This actually allowed simplifying the code a bit,
since CoglMatrixEntry only stores a pointer to its parent, and that's
all we need to know for left-hand multiplication.
