hqdn3d video filter, ported from mplayer

High Quality DeNoise 3D, a port of the MPlayer filter, removes high-frequency
noise while minimizing blending artifacts by performing a 3-way low-pass filter

To open source programmers across the world:
   MAY THE FOO
   BE WITH YOU

(PS: code-fu, that is)
(PPS: blame funman)
