#13382: Bug in polygon OR operation with collinear points
------------------------------+---------------------
 Reporter:  k.daloukas@…      |      Owner:  (none)
     Type:  Bugs              |     Status:  new
Milestone:  To Be Determined  |  Component:  None
  Version:  Boost 1.66.0      |   Severity:  Problem
 Keywords:                    |
------------------------------+---------------------
 When OR operation is performed between 2 non-overlapping polygons that
 contain collinear points with the same y coordinate, the resulting set is
 empty. However, if collinear points are removed, the resulting set
 contains the 2 polygons.

 If generic polygon_set_data objects are used, the OR operation works fine.
 The problem appears when polygon_90_set_data objects are used in order to
 increase efficiency of boolean operations.
