Program Summaries
Flash: Continuously fill the color map with random values. This is not as useless as
may sound; often anomalies hidden in an image become obvious.
Mono: Set the color map to be linear ramp from 0 through 255.
Gamma: Set the color map to gamma (= 2.2) corrected grayscale.
Lum: Converts pseudo-color to luminance; converts the colordisplay accordingly.
Cycle: No graphics lab is complete without this program.
PrintColorMap: Prints the values of the color map entries as three columns (r, g, and b).
