The Distance Node in 2.49/2.5/2.6 pre-tiles has a different calculation for RGB and YCC. While RGB
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.
