In my experience the default assumed_gamma changes the input colors
(eg. the ones in an image map). By specifying assumed_gamma 1 you get
POV-Ray to show the same colors as you get by viewing the image map
with an image viewer (which does not perform any kind of gamma correction).
The default assumed_gamma makes the image map to look way too light.
