8x and 16x MSAA should work now, so we no longer need to deal with those
separately. We have more accurate checks for when it's supported or not
in place already.
2x MSAA isn't supported at all until v12, which we haven't finished
wiring up yet. So let's leave that one for now... We'll need some more
fixes for that anyway.
