How to draw a six-leaves kawung given a side length AB
1. Draw perpendicular bisector. The intersect O will be center of a circle circumscribing the hexagon
2. Draw circle with center at O, with radius OA
3. Draw circle centered at A, with radius AB. The intersection between this circle and larger circle is the vertex of the hexagon
4. Repeat step #3 five times
5. 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.
