[...] OS X supports drawing subpixel-AA to partially

I would have expected that drawing onto a completely transparent
surface on OS X would always result in no sub-pixel aa effects
And apparently that's what happened on 10.6, where the test doesn't
fail. Looks like something was broken on 10.7 or 10.8.
