Jonas Ådahl 468bf81307 surface-actor: Remove 'pre-paint' vfunc
The vfunc was not tied to "paint", but was used by MetaWindowActorX11
as part of the "update" mechanisms. In order to make that more clear,
special case it in MetaWindowActorX11 by type checking the surface
actor, handling the case without MetaSurfacActor abstraction.
