    actor: consider empty pv ok in set_default_paint_volume
    
    In _clutter_actor_set_default_paint_volume we were returning FALSE if an
    actor has an empty allocation because we were claiming it doesn't have a
    paint-volume. Actually an empty/degenerate pv is valid and has different
    semantics to returning FALSE because FALSE means the pv is unknown and
    so Clutter will have to assume the worst - that the pv is basically
    un-bounded.
