All raw functions and tokens from the NV_primitive_restart extension not already in the OpenGL 3.1 core, see http://www.opengl.org/registry/specs/NV/primitive_restart.txt. NOTE: The OpenGL 3.1 core has some functions and tokens with the same names, but with different semantics and values, so we use a suffix in those cases.
