// miny 2 3 4
// midy 1 9 5
// maxy 8 7 6
// Which gives us a coincident start and end point, which is incidental to this technique, but still doesn't
// form a closed path, so we still need to close the path to connect the ends correctly.
// Thus we start by moving to point 1, then adding arcs through each pair of points that follows.
// You could use a similar tecgnique to create any shape with rounded corners.
// Start at 1
