Since commit c255031b6d, we allow some modifier+scroll events to
pass through to Clutter to enable gnome-shell to handle them. That
action shouldn't trigger a modifier-only action at the same time, so
reset the corresponding tracking just like we do for modifier+click.

Since commit c255031b6d we pass scroll-events through to
the compositor if the window_grab_modifiers are pressed;
in order to allow gnome-shell to check for those events,
expose the struct member as a MetaDisplay property.
Also take the opportunity to pick a more generic name, now
that the modifier is no longer used exclusively for mouse
clicks (unless we maintain the notion of scroll events as
button 4 and 5 "clicks").

The other end of the PipeWire stream can set the buffer data type to a
bitmask of supported buffer types. We should respect this, and not
attempt to allocate a DMA buffer if it isn't asked for.

Instead of getters, pass the width, height and stride around when
relevant. This also removes the redudant "stream_size" and
"stream_height" variables from the src struct, as they are already part
of the video format.

Previously we were setting the FBO's viewport to be the same dimensions as
the stage itself for compatibility. This works for most cases, but not if
the actor is larger than the stage. In that case it could cause excessive
clipping if the actor's transformed screen position was negative, which
is seen in https://gitlab.gnome.org/GNOME/gnome-shell/issues/2087
Also if a small actor paints to its negative dimensions (like a box-shadow)
then we might be missing those pixels on the left or top, even though
they're inside the paint volume.
Now we set the viewport dimensions to match the area we're actually
rendering so the FBO contents are never over or under clipped.
Fixes: https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/3068
Although if you try using shadows larger than that (like in
gnome-shell#1090) then you will also need gnome-shell!1417.

We had been doing it backwards as far back as e3966882e8 which meant
that we were translating by `fbo_offset / resource_scale` stage units
instead of just `fbo_offset`.
Because `fbo_offset` is in stage units already, it's not scaled and so
needs to be applied after the unscaling from texels to stage units.

Mutter freezes Xwayland commits when resizing windows, and thaw them in
the window actors' after_paint() for X11.
Yet, after_paint() could be never called, as when a new window is mapped
while the overview is active in gnome-shell.
As a result, the content of the X11 window will remain invisible to the
overview.
Add a new window actor API to tell whether commits can be frozen. For
Wayland window actors, this always return FALSE, whereas for X11 window
actors, it checks whether the Clutter actor is mapped.

When (un)maximizing, (un)fullscreening, the move/resize action is
flagged with 'ACTION_MOVE' and 'ACTION_RESIZE' , while e.g.
'appears-focus' does not.
When a client misbehaved and didn't immediately reply to a configure
request with a commit with the corresponding ack_configure, the
following commit would trigger a oddly timed move, making the window
appear to move back to a previous position.
Avoid this issue by only carrying over the target window position if the
configuration actually contained a new position.
We cannot only rely on the flags however, as e.g. a new position should
be respected during interactive resize, even though only 'ACTION_RESIZE'
is passed in such scenarios.
Do the same for the size, except if the window state dictates that the
size is fixed to a certain size, e.g. being fullscreen or maximized.

It's currently only handled by a surface backend framebuffer (assuming
the right GLX extensions are available). While it's theoretically
possible to do the same with the offcreen by having multiple textures,
it's not supported, so leave the FBO variant with a single warning if we
end up there.

The object was still pretending to be CoglFramebuffer itself, by using
naming and calling conventions making it seem like that. Fix that by
passing around the driver instead of the framebuffer.

Mutter needs to fetch the X11 Window ID from the onscreen and did that
by using an X11 specific API on the CoglOnscreen, where the X11 type was
"expanded" (Window -> uint32_t). Change this by introducing an interface
called CoglX11Onscreen, implemented by both the Xlib and GLX onscreen
implementations, that keeps the right type (Window), while avoiding X11
specific API for CoglOnscreen.

Mutter didn't use the APIs for resizeability of CoglOnscreens but
managed the size itself. For the native backend we don't ever resize
onscreens. Thus, remove this unused functionality.

The framebuffer driver was lazilly initialized on demand in some cases
(onscreen), and up front other (offscreen). Replace this with a more
predictable up front initialization, done at framebuffer allocation.
