Comment (by Henrik Zimmer <henrik@…>):

 Further description of the problems:

 In the first problem scenario (without using define
 BOOST_GEOMETRY_NO_ROBUSTNESS) the two polygons barely touched, hence I
 would except the intersection to be empty and the difference to be equal
 to one of the input polygons. (But it was also empty)

 In the second problem scenario (with define BOOST_GEOMETRY_NO_ROBUSTNESS)
 the two polygons had a clear intersection, hence I would expect neither
 difference nor intersection to be empty.
