Not much use I guess, but on sse2 8 bit content it tests OK = faster +
md5sum the same as without the patch.

Are you considering going further with this?

Being sharper than yadif/preserving weave is nice, but for some SD
(viewing scaled up) yadif wins on moving low angle diagonals, which end
up stepped.

 From memory when testing intel h/w deint it did a nice motion adaptive
deint of the same scene without steps. The possible difference being 
that its "bob"
also did some sort of edge detection/interpolation.

the scene in question, bwdif jaggies the cue when at a shallow angle.

The algorithm used by the h/w I tested. p259
