47144253e4 cullable: Turn cull_out / reset_culling into a separate interface
Instead of hardcoded knowledge of certain classes in MetaWindowGroup,
create a generic interface that all actors can implement to get parts of
their regions culled out during redraw, without needing any special
knowledge of how to handle a specific actor.

The names now are a bit suspect. MetaBackgroundGroup is a simple
MetaCullable that knows how to cull children, and MetaWindowGroup is the
"toplevel" cullable that computes the initial two regions. A future
cleanup here could be to merge MetaWindowGroup / MetaBackgroundGroup so
that we only have a generic MetaSimpleCullable, and move the "toplevel"
cullability to be a MetaCullableToplevel.

This does better reflect what this region is used for.

580feb0c85 compositor: rework how backgrounds are managed
Background handling in GNOME is very roundabout at the moment.

gnome-settings-daemon uses gnome-desktop to read the background from
disk into a screen-sized pixmap. It then sets the XID of that pixmap
on the _XROOTPMAP_ID root window property.

mutter puts that pixmap into a texture/actor which gnome-shell then
uses.

Having the gnome-settings-daemon detour from disk to screen means we
can't easily let the compositor handle transition effects when
switching backgrounds. Also, having the background actor be
per-screen instead of per-monitor means we may have oversized
textures in certain multihead setups.

This commit changes mutter to read backgrounds from disk itself, and
it changes backgrounds to be per-monitor.

This way background handling/compositing is left to the compositor.
