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.
