It looks to me like it is indeed not possible in GL to sample integer textures as bind_as_float (only when normalized does conversion to int happen), and I don't know if hw could do it. Probably the same for surfaces. If we have bind_as_float we really should rename SCALED to INT probably in a future patch.
