...ing it and doing more enable/pointer calls. VAOs are not constants.)
More info in response to Patrick's questions:
The default for a newly created VAO is that it's empty (AFAIK). No geometry at all, not even vertexes, so if you try to draw it, you'll get an OpenGL error. This is reasonably sane, a...

...
Luis Casillas's answer gives a lot of great info about what rank 2 types mean, but I'll just expand on one point he didn't cover. Requiring an argument to be polymorphic doesn't just allow it to be used with multiple types; it also restricts what that function can do w...

How exactly does the “Specific Version” property of an assembly reference work in Visual Studio?
... decision whether to perform the "Specific Version" check on two pieces of information found in the .csproj file:
