FS#89 - PPM output garbled for bit depths other than 8 bits
When choosing PPM output with a bit depth other than 8 bits per color channel (e.g. +FP16), POV-Ray messes up the colors (see thread news://news.povray.org:119/4babb48f$1@news.povray.org)
There are actually two separate errors in the code, pertaining to (a) bit depths lower than 8 bpcc, and (b) bit depths greater than 16 bpcc. In both cases the respective formula to convert from floating point to integer is plain wrong.
fixed with change #4932
