> The problem is that glGetFloatv() doesn't know about GL_MODELVIEW_MATRIX (and that it returns 16 values). Is there a definitive list somewhere of the names that can be queried and the versions of OpenGL they apply to?

Using a predefined list of lengths could be a solution. I think that's 
how PyOpenGL does it. There's a list of all constants for example here:


However, there are a few hundreds of them!
