Robert Mader 372d73e275 surface-actor: Cull out surfaces without alpha channel
If a opaque region is explicitly set we should not consider the surface
opaque, as that implies e.g. a shape region is set.

If no opque region is set but the texture does not have an alpha channel,
we can savely cull it out.
