I have been playing around with the heteroMF function (mainly with
isosurfaces in MegaPOV) and it seems to create output in the range of -1 to
1.  Now, unless I am mistaken, maps (such as color_maps, pigment_maps, etc)
take output in the range of 0 to 1.  If I am right about the heteroMF's
output range, one would need to rescale that functions output and add an
offset to get results that would all fall in the range 0 to 1.  Should the
heteroMF's output range be adjusted to be consistent with the other POV
patterns?  Or am I just lazy?  (or just wrong about my conclusion on the
heteroMF's output?)
