Milestone:  To Be Determined                    |  Component:  polygon
  Version:  Boost 1.54.0                        |   Severity:  Problem
 Keywords:                                      |

 The attached program uses boost::polygon to
 slice up a figure (with a "hole" cut out of it) into horizontal
 trapezoids. The output I get is:
 Output:
 polygon (4 3) (4 0) (0 0) (0 3) (4 3)
 ...which is clearly wrong. I am pretty sure my code is correct,
 because if I replace bg::HORIZONTAL with bg::VERTICAL, I get the
 correct output of a bunch of vertical trapezoids.
