rfelker eeec580edc small change to field-matching metrics which hopefully makes a big
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)"...
