I understand that POV uses double precision floating point numbers
internally, it then clips them to 0..1 and scales appropiately to save to a
24-bit bitmap.  If this is correct, is there any way to output the raw
double float values for each rendered pixel to a file?  Has anyone written a
patch to do this? It doesn't seem like it will be that hard.

I would like to use the raw full-precision values in a program I am writing,
so the format doesn't matter really.
