The gain parameter modifies the overall curve gain in relation to the transfer curve (Yout =
Yin).

The inflexion point is dependant either on the average brightness (when using
brightness estimator values) or the input value (when using manual mode).
The range parameter modifies the slope of the Ym segment. Slope values are
algorithm-dependant.
