It may be a useful alternative to the existing gamma control for laptops in a bright environment, etc. (raising contrast gives less of a gray/washed out look than raising gamma, but as a disadvantage, colours near white get clipped to white.) It's also implemented for both GLSL and SDL gamma ramps, but only if USE_GAMMA_RAMPS is set to 1. Since USE_GAMMA_RAMPS is 0, currently it only works with GLSL. git-svn-id: svn://svn.code.sf.net/p/quakespasm/code/trunk/quakespasm@1290 af15c1b1-3010-417e-b628-4374ebc0bcbd
