Detailed Description

gamma correction

Input is a gamma correction value in the range ]0.0 .. 10.0]; the color values get corrected using

col(r,g,b) = clamp(pow(col(r,g,b), 1.0 / gamma), 0.0, 1.0) Red, Green, Blue, Luminance and Contrast correction

Input are percent values from [-1.0 .. 1-0] which correspond to -100% to 100% correction of Red, Green, Blue, Luminance or Contrast. 0.0 means no change of the corresponding channel. All these are combined (but can be used single) to
