I'm wrong about that; it CAN be used and does work. (I must have been looking at
a different test image; sorry for the misinformation.) The only minor glitch is
that the smooth area of the resulting HF not covered by the image_map is
automatically at full height--not at y=0--as if that part of the HF function
were *pure white.*

Hmm. That's because ONCE(and INTERPOLATE and MAP_TYPE) can't be used in a
regular height_field. Forgot about that. Wheras they CAN be used in a HF
function.
