// This is a simple lightweight DeInterlace method that uses little CPU time

// but gives very good results for low or intermedite motion.

// It defers frames by one field, but that does not seem to produce noticeable

// lip sync problems.

//

// The method used is to take either the older or newer weave pixel depending

// upon which give the smaller comb factor, and then clip to avoid large damage

// when wrong.

//

// I'd intended this to be part of a larger more elaborate method added to 

// Blended Clip but this give too good results for the CPU to ignore here.
