description: >
  A simple desaturation/saturation effect. We use the Rec. 709
  definition of luminance (in linear light, of course) and linearly
  interpolate between that (saturation=0) and the original signal
  (saturation=1). Extrapolating that curve further (ie., saturation > 1)
  gives us increased saturation if so desired.
