Yes, but as Brice said before we shouldn't enable these options unless we
know what the drawbacks are. Maybe you can investigate about that?
My point is that if we don't figure that out satisfactorily in time, we could
just enable the Composite extension, which sounds fairly safe, and seems to be
enough for Intel cards. And Intel happens to be the card brand we have the
best driver support for (compared to a RE'd driver for ATI and nothing for
nVidia), so focusing on it makes sense to me.
