Correct. I recall JonCruz saying that PJRM was working on stuff for it
to apply to all objects, but that was a long time ago. Since then, I
know that JonCruz had started refactoring our handling of "paint", which
was an important part of making this all useful. Unfortunately, I
haven't seen him in a couple months now, so who know if it's still being
worked on. :(
