Box Blur

This Box Blur filter is an external filter (plugin) version of VirtualDub's internal Box Blur filter by Avery Lee. I made it to allow it to be imported into Avisynth scripts. I also added an opacity slider to allow an alpha blend of the filtered ouput and the source frame, and the capability to animate the filter away to a null operation (no filtering) by setting its radius, power, or opacity to 0.

Version 1.5 (includes source code under GPL)
