How to draw a eight-leaves kawung given a side length AB
1. Draw perpendicular bisector. This line will intersect AB at midpoint
2. Draw arc centered and midpoint, with radius A - Midpoint. This arc will intersect perpendicular bisector at point X
3. Draw circle centered at A, with radius AX. This will intersect perpendicular bisector at origin of circle circumscribing the octagon
4. Draw circle circumscribing the octagon
5. Draw arc centered at A, with radius AB. This arc will intersect circle. This will be the vertex of the hexagon
6. Repeat step #5 seven times.
7. 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.
