compositor: Frames where we introduce alpha can't obscure anything

When a pad has alpha != 1.0 it means that the resulting frames will
contain alpha and thus can't fully obscure with a lower zorder.

Also simplifies the other checks as blending with an OVER or on a
transparent is not a no-op as previously assumed.
