I don't understand this statement.  Do you mean that for example
128 would come out as 128/255=.50196 instead of .5?  That happens
to be correct.  In fact, I'd wager that if you render a scene with
a solid pure-ambient .5 background and no gamma correction, you 
should get pixels with the value 127, because POV will round down.
You should divide by 255, if for no other reason than because POV
multiplies by 255 (assuming you're outputting 8 bits per channel).
