9988	boost::geometry::intersection returns opposite of intersection	ajoseph4@…	Barend Gehrels	"For some geometries boost intersection  returns a geometry that is the opposite (the geometric difference) of the intersection. Here is an exampl.
Geometry 1:
POLYGON((-84.5922 35.9063, -84.5924 35.9064, -84.5929 35.9062, -84.5926 35.9057, -84.5927 35.9056, -84.5926 35.9054, -84.5915 35.9058, -84.5915 35.906, -84.5918 35.9065, -84.5922 35.9063))
Geometry 2:
POLYGON((-84.5932 35.9051, -84.5932 35.906, -84.5921 35.906, -84.5921 35.9051, -84.5932 35.9051))
Output:
POLYGON((-84.5928 35.906, -84.5926 35.9057,-84.5927 35.9056, -84.5926 35.9054, -84.5921 35.9056, -84.5921 35.9051, -84.5932 35.9051, -84.5932 35.906, -84.5928 35.906))
Correct Output:
POLYGON ((-84.5921 35.905581818181815, -84.5926 35.9054, -84.5927 35.9056, -84.5926 35.9057, -84.59278 35.906, -84.5921 35.906, -84.5921 35.905581818181815))"	Bugs	closed	To Be Determined	geometry	Boost 1.55.0	Problem	invalid	intersection
