Subject: [PATCH] $parallel_degrees_limit decreased, 3 to 0.1, #704

Geometry::lines_parallel() test used for collapsing adjacent colinear
lines was too loose in testing for colinearity, because of this constant
setting. Gradualy curving and high-res outer perimiters would
over-simplify into straight lines.
