fbo_blit doesn't exist yet here, and may be unavailable depending on
available extensions or ORM used. You pretty much never want to use
ffp_blit if you can help it, due to the huge amount of state
invalidation that does.

Of course arbfp_blit is somewhat broken in the sense that it doesn't
actually create a shader for non-complex fixups and silently lets
ffp_blit handle the blit, but that's something that should be fixed,
not disabled.
