10843	polygon / voronoi: points on line segments yield errors	maik.nijhuis@…	Andrii Sydorchuk	"http://www.boost.org/doc/libs/1_57_0/libs/polygon/doc/voronoi_main.htm says:
""input segments should not overlap except their endpoints""

Their is no restriction on input *points*, though, so I conclude that points may lie on line segments. However, construct_voronoi fails with the following input:
- One point, at (1,  0)
- One line segment, from (0, 0) to (2, 0)

The output has only one vertex, with invalid x and y coordinates.

Fortunately, I can easily work around the issue:
- Before calling construct_voronoi, I was already using intersect_segments for creating proper input segments. When I add the points as zero-length segments in the input for intersect_segments, intersect_segments will cut segments when there is a point at the segment.
- Since intersect_segments discards zero-length segments, I still pass the points separately, as I did before.

Could you please either update the documentation or resolve the issue otherwise?"	Bugs	closed	To Be Determined	polygon	Boost 1.58.0	Problem	fixed
