I've assembled a list of extensions I *think* are not demanded by
any current openGL specs, but I may have missed some.
(I find it weird that I VAO's in any of the specs, for example)
I could add all of them to a separate section to track them,
or I can leave it as is and drop this patch. Up to you guys.
