Other than 16bit height fields, can pov-ray write 16 or 32 bit output for
images instead of 8?

"Most of these formats output 24 bits per pixel with 8 bits for each of red,
green and blue data. PNG and PPM allow you to optionally specify the output bit
depth from 5 to 16 bits for each of the red, green, and blue colors, giving from
15 to 48 bits of color information per pixel. The default output depth for all
formats is 8 bits/color (16 million possible colors), but this may be changed
for PNG and PPM format files by setting Bits_Per_Color=n or by specifying +FNn
or +FPn, where n is the desired bit depth."

Sounding suspiciously like the documentation, I looked for this paragraph
and found it. Argg. Just like tests in college -- you think "where the hell
did this question come from" during the test, and only afterwards find it
bolded in the text that you had read several times in preparation.
Thanks,
