## Discussion

\abstract Specifies a three element polynomial for mapping y axis UV parameters with an adjustment using the equation `y' = polynomialY[0] + polynomialY[1]*y + polynomialY[2]*y^3`.
\discussion The values are in a CFArray of three CFNumbers(float) in the order polynomialY[0], polynomialY[1] & polynomialY[2].
The polynomial transform origin is at the center of the frame. The default values of elements of polynomialY[] are [0.0, 1.0, 0.0].
