We should use the GL 3.0 functions for transform feedback. That way we don't have to rely on what extensions are exposed, as EXT_transform_feedback is part of the GL spec anyway. Exposing the extensions incorporated into the GL spec is optional and NVIDIA obviously decided not to do so in this case.
