Yes, pure white!  I just tried it. It's one of those "raise to the zeroeth

The proper way to do what I intended would be to comment out the
assumed_gamma. I was getting confused in my late night thinking. OTOH,
setting  "HF_Gray_16 on" probably does something like this... I'll have to
check that out when I next go back to messing around in heightfields.
