  According to Ed, "brightness" is in fact "gamma" which should have very
little to do with the endpoints of the histogram (but, given Vuescan's
histograms, I'll have to make sure of what I say).  The proper tools for
avoiding clipping the histogram endpoints should be the whitepoint and
blackpoint percentage values ... i.e., seting them to very small values ...
e.g., 0.001.
