*
* Apply a boxblur debanding algorithm (based on the gradfun2db
* AviSynth filter by prunedtree).
- * Foreach pixel, if it's within threshold of the blurred value, make it closer.
- * So now we have a smoothed and higher bitdepth version of all the shallow
- * gradients, while leaving detailed areas untouched.

* Dither it back to 8bit.
