This also has the benefit of preserving the API that has been in place for PS/PDF surface since the (experimental) stuff in 1.0.0. Track API change. Continue testing PS/PDF surfaces in the CAIRO_CONTENT_COLOR mode but do it by rendering to an intermediate similar surface rather than constructing the target surface differently.
