BooleanOperations

Returns intersection points between boundaries of two polygons as two array of points
Points in the first array belong to first polygon, points from the second - to the second. Points in each array are ordered according to the direction of the correspondent polygon

Returns boundary of intersection between two polygons as two arrays of shapes (Segments/Arcs)
The first array are shapes from the first polygon, the second array are shapes from the second

Intersect two polygons and returns new polygon Point belongs to the resulted polygon is it belongs to the first AND to the second polygon

Returns boundary of subtraction of the second polygon from first polygon as array of shapes

Subtract second polygon from the first and returns new polygon Point belongs to the resulted polygon if it belongs to the first polygon AND NOT to the second polygon

Unify two polygons polygons and returns new polygon.
Point belongs to the resulted polygon if it belongs to the first OR to the second polygon
