24  * @file
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...
