calculate the distance in 3d between R,G and B, the YCC only takes Cb and Cr into consideration. This commit makes COM_DistanceMatteOperation inheritable and expose the calculate distance function to be re-implemented for the YCC node operation. Thanks Troy Sobotka for the report over email. Patch incorporates review suggestions by Jeroen Bakker.
