hmm, this seems to be the same algorithm as the vf_sab filter, with some 
interresting additions and mmx optimizations, maybe it would be better to add 
these to vf_sab.c

it also seems to be very buggy
* the second while loop in scanCW doesnt look right
* pass=range is missing before the second loop in scanC & scanCW and there 
seems to be no check against acessing pixels prior and after the image
* it seems the filter is simply applied to 0..height*stride, this isnt really 
good, it shouldnt write to pixels outside the w*h rectangle
...
