Detailed Description

Representation of a 2D point, and potentially its location relative to a polygon. As nodes can be shared between edges it is handled with ref counting.

WARNING different from 'computeAngle' method ! The returned value are not in the same interval ! Here in [0; Pi). Typically this method returns the same value by exchanging pt1 and pt2. Use in process of detection of a point in or not in polygon.
