//
//  Returns the given value with gamma correction applied to it.

//      gamma       correction value, real
//      x           value, real
//
//  If x varies over the [0,1] interval, then the result also
//  varies over that interval. The 0 and 1 endpoints of the 
//  interval are mapped onto themselves. Other values are 
//  shifted upward toward 1 if gamma is greater than 1 and 
//  shifted downward toward 0 if gamma is less than 1.
