BTW: That old problem had strange effects: no only of the z effect of the
function being reversed to '-z', but also x to -x. It was -- is? --a
'double-reversal' mirror effect...with the 'origin' of the function moved to
z=1, not at <0,0,0>.
I thought for sure that this had been corrected, but I have not played around
lately with such height_fields to see.
