25 * ColorMatrix 2.0 is based on the original ColorMatrix filter by Wilbert
26 * Dijkhof. It adds the ability to convert between any of: Rec.709, FCC,
27 * Rec.601, and SMPTE 240M. It also makes pre and post clipping optional,
28 * adds an option to use scaled or non-scaled coefficients, and more...
