FS#2302 - polygon.getSelfIntersectionPoints(tol) returns 3th invalid point for a segment crossing in a node.

Andrew,

In the attached dxf:
Besides that it is clear that duplicate vectors are not filtered ...
Where a segment is crossing in another node a non valid node is returned as self-intersection point.
Seems to be unrelated to CW/CCW or tolerance.

Where 2 nodes coexists 4 duplicate vectors are returned.

Regards,
CVH
