This limit is fixed in Mesa core and cannot be changed. It only affects ARB_vertex_program and ARB_fragment_program. The minimum value for ARB_vertex_program is 1 according to the spec. The maximum value for ARB_vertex_program is limited to 1 by Mesa core. The value should be zero for ARB_fragment_program, because it doesn't support ARL. Finally, drivers shouldn't mess with these values arbitrarily. Reviewed-by: Ilia Mirkin <imirkin@alum.mit.edu>
