Bitexact equivalent version of mp=sab, I'll drop the wrapper as this
is approved.

What it is really lacking is an explanation of how it compares with
the other blur filters (smartblur, boxblur), and how the various
parameters affect the output (e.g. the pre-filter thing), and MPlayer
docs are no help.

Can someone help with that? Also an explanation of the employed
algorithm would be useful (michaelni?).
