improvement to results. inter-field comparison is now counterbalanced with intra-field total (vertical) variation. this means that areas of extreme high frequency content, which become aliased within individual fields, will not interfere with field matching. examples: white noise effects, small kanji, very small latin text, ... may still need tweaking. please report regressions. this change will likely be made optional in the future (right now it's enclosed in "if (1)"... git-svn-id: svn://svn.mplayerhq.hu/mplayer/trunk@15722 b3059339-0415-0410-9bf9-f77b7e298cf2
