/**
 * Shows how to create an `Arc` centered on the window. The start and end angles of the arc increase 36 degrees
 * per second, resulting in an animated effect.
 *
 * The `contour` property of the arc is used for rendering.
 *
 * The start, mid and end points of the arc are queried using it's `position()` method
 * to draw small circles at those locations.
