This shouldn't happen. Without assumed_gamma specified, no gamma 
correction should be done. It is documented as working this way in both 
the manual and the source code. opts.GammaFactor is initialized to 
something other than 1, but that shouldn't matter as long as the 
GAMMA_CORRECT flag in opts.Options isn't set.
