     * When used with the Background node, default is directionIsDown is true if
     * interpolating the skyColor down from the Zenith. When interpolationg up from
     * the Nadir i.e. interpolating the groundColor, the directionIsDown is false.
     *
     * The first angle is never specified, it is the Zenith (0 rad). Angles are specified
     * in radians. The geometry is thought a sphere, but could be anything. The color interpolation
     * is linear along the Y axis in any case.
     *
     * You must specify one more color than you have angles at the beginning of the colors array.
     * This is the color of the Zenith (the top of the shape).

     * @param boolean topDown Whether to work top down or bottom up.
