I want to write a function to draw regular convex polygons with arcs
instead of straight lines. I made an approximation for a square with:
     20    -34.5  40   60  120  arc
    -34.5   20    40  330   30  arc
     20     74.5  40  240  300  arc
     74.5   20    40  150  210  arc
    stroke

How would I make a function that would do this for convex polygons
with sides from 3 to 12 in a correct way? (If you do a ‘4  dup  scale’
on my example you see it is not more as an approximation.)
