I think Rik is convincing me that we shouldn't expose mozOpaque or any
other explicit subpixel AA control to the Web. It will be very easy for Web
authors to test it in one place and discover that it works without
realizing that they're causing problems for some users.

I think a fully automatic solution that tries to use subpixel AA but is
always able to render grayscale AA if needed is the way to go. Possibly
with an author hint to suggest opting into a more expensive rendering path.
