ffmpeg | branch: master | Martin Storsjö <martin at martin.st> | Mon Aug 27 12:33:42 2012 +0300| [2bd67175c7e16c1f5da15c9e55ae6db4ab1d23fd] | committer: Martin Storsjö

vf_hqdn3d: Don't declare the loop variable within the for loop

This C99 feature is generally not used in the libav codebase,
since it breaks building with some fringe compilers (GCC 2.95,
MSVC).
