> Can POV output in 16 bit per channel mode?

Yes, the PNG and PPM file formats allow you to specify an output bit depth
from 5 to 16 bits per channel. This is done via the commandline. The docs
will tell you how to do.

Not to my knowledge, but there's a slow work-around: It's possible to use a
function to evaluate a pixel, and output the info with a loop running over
all the pixels. Beware it's done in SDL and therefore it's slow. It may also
require a two-pass rendering, where you first render the image, and then
start another render that loads the first image and evaluates it... Not so
elegant solution.

By the way, what is a FUT warning?
