I had forgotten that! :-O  Thanks for the reminder.

BTW, re: the discussion there of 'bending the slopes of height_fields': It can
be done in an alternate way now, using POV-Ray's 'blend gamma' feature-- i.e.,
by purposely changing the gamma of the image that's used to make the HF. That
effectively changes the otherwise 'linear' slope of HF contours to more of a
curve. For example, HF mountains made this way look more natural to my eye--
like the mountain's slopes have naturally eroded. (There's also a HF difference
between images SAVED at different gamma values, for the same reason-- 1.0 being
a linear slope, 2.2 being more of a curve.)
