In everything I've read on the web about displacement mapping, the term
itself always goes hand-in-hand with using polygonal models (and having to
subdivide the surface to get good results.)  Since POV's isosurfaces are
math constructs instead, and by nature "displaced surfaces"--and since an
image_map can be used as an isosurface function to further perturb such a
surface--it seems to me that this image_map technique could also be
called "displacement mapping."  Or is there a different term for it?
