The nonlinearity of a color display is often characterized by a
"gamma correction" value; calib provides a crude method for determining
this value for a particular monitor. It displays two rectangles: one
formed of alternating black and white scanlines and one formed of a
single, solid color. Move the slider until they match; the number
displayed above the slider is the gamma-correction factor.
