  There should be a way for the user to specify an assumed gamma for input
images, so for PNGs with no gamma information at all, the user-defined
assumed gamma should be used.

  Of course if the user has not specified an assumed gamma for the input
image either, then the default should probably be Display_gamma (ie. so that
the image will look in POV-Ray the same it looks when viewed with some
image viewing program).
