Detailed Description

Contains the coefficients for a common transfer function equation, specified as a transformation from a curved space to linear.

LinearVal = C*InputVal + F , for 0.0f <= InputVal < D LinearVal = (A*InputVal + B)^G + E, for D <= InputVal <= 1.0f

Function is undefined if InputVal is not in [ 0.0f, 1.0f ]. Resulting LinearVals must be in [ 0.0f, 1.0f ]. Function must be positive and increasing.
