Why GstGlFuncs

[Matthew Waters]

Because not all platforms expose all OpenGL functions in their OpenGL 
library.  e.g. Windows only exposes up to OpenGL 1.1 and everything else 
has to be wglGetProcAddress()ed (dlsym()) somewhere.  Also, the returned 
function pointer can be different for each OpenGL context created (again 
Windows).

Cheers
