--- Comment #24 from Ilia Mirkin <imirkin at alum.mit.edu> ---
"""
But according to next comment it should be 0 because of the BlockB[0] was
optimized
and there is the BlockB[1] only:

   /* The ARB_shading_language_420pack spec says:
    *
    *    If the binding identifier is used with a uniform block instanced as
    *    an array then the first element of the array takes the specified
    *    block binding and each subsequent element takes the next consecutive
    *    uniform block binding point.
    */
"""

I don't think that's enough justification for the "mesa" way of doing it.
Whether a block is eliminated or not is not specified by GLSL spec. Would be
good to get some more experienced opinions on this. [Not mine...]
