Yeah, would be good as that's required for 3.0 core context
support. Note that most of the VAO work is actually in the Render
extension drawing code, and I plan on reworking all of that in the
coming months. I've already done render glyph support, which has some
of infrastructure stuff already completed.

I doubt we can require it, but we could obviously have dire fallbacks
when it's missing.
