GSGraphicalPathView Class
A graphical path view allows a user to draw quadratic bezier-curves and connecting them. That is useful for
animations like for the "Move XXX along Path" scene commands. It stores an array of curves and each curve has the format: { pt1: { x, y }, cpt: { x, y }, pt2: { x, y } }.
- pt1 = Start Point
- pt2 = End point
- cpt = Control Point
