How to draw a three-leaves kawung given a side length AB
1. Draw perpendicular bisector of AB
2. Draw perpendicular bisector of BC
3. Draw perpendicular bisector of CA. The intersection of perpendicular bisector is the center of circle circumscribing the triangle
4. Draw N-Leaf Kawung, based on quadratic bezier curve. We can start at (0,0), mid point between vertrices and control point, and the vertices as the end point.
