Oh, and one more, over here I set this false, as I don't see a really reasonable
way to plumb this in here atm. Idk if this would be used for the compositor
output surface, in which case it should be true, but it surely is used for other
things as well, where it should be false. So yeh.

Yeah, right now, this is common code. We'll have to plumb this sort of things
from the client API.
Maybe add a TODO(piman) there.

Thanks! Done.
