It could be done with a macro, using eval_pattern(), eval_pigment(), or
trace() to calculate the height for each point. You might not get the
memory advantages of a height field(*)...but that wouldn't be a problem
if there is only one of them in a scene.
(*)Another idea, make bicubic patches act like meshes, so pointers to
the patch are used instead of copies. Or maybe a "store_references"
aspect for all objects, which controls the way they are copied. Maybe
for POV-4.0?(It might be too difficult/ugly to implement in the current
C source, but should be quite easy in C++)
