  I think that one of the most practical reasons for moving ior outside
the texture block is that when it was in the finish block it was possible
to define an ior which changes along the surface of the object (ie.
different parts of the surface have different ior), which gave a physically
completely incorrect result (in reality IOR never changes only in the
surface of an object).
