Gamma function tests

by Billy Biggs <vektor@dumbterm.net>

The following images were generated to try and test how close my monitor is to various gamma standards. The left hand side of each image is a repeating pattern of pure white and black pixels:

    [ BLACK  WHITE ]
    [ WHITE  BLACK ]
    

The right hand side is half-intensity grey according to each standard. They should look close to identical in a properly configured viewing environment for that standard.
