Even then there are no guarantees that the extension functions are the same
(they might be the same make and model, but they have different
resolutions/bitdepths/other configuration). Interestingly enough on Linux there
is a guarantee that the extension methods are the same, but not on Windows
(AFAIR).
I looked at the multi-context support in GLEW a while ago and didn't like it
very much. It made the whole thing very complicated... Even if we don't use it
I'm not sure how GLEW will handle multiple threads, especially situations where
different threads open and use the context. We need to look at that carefully
before we go for something.
The one real disadvantage is that it's another dependency...
