I thought about that too, but I want to render a lot of materials this way and
thought it may be a good addition to POV-Ray anyway, since a lot of transparent
materials have nonlinear dispersion.  I found Element_IOR in lighting.cpp that
returns a modified ior dependent on disp and nelems so perhaps just that one
function could be modified to read from an array instead of disp and nelems,
but I don't know if that is the only place I would have to modify.
