My tests with the Cornell box indicated that to match their radiosity
engine gray_threshold 0 is required.

Too saturated lighting results from not using assumed_gamma 1.0, light
sources without fade_distance and too saturated surface and light source
colors.

Of course it's possible the Cornell University Program of Computer Graphics
did a sloppy job with their engine but somehow I doubt it.

For artistic purposes it's good to have a tunig parameter for matching
personal tastes.
