+/// \a Arcs On connection of straight edges, tangent arcs are created,
+///    except the case of too short edges. Radius of arcs equals to the offset value.
+/// \a Lines No arcs is created on the connection of the resulting lines,
+///    adjacent lines are prolonged to the point of their intersection.
