48 Draws a randomly-colored Voronoi tessellation, and periodically zooms 
49 in and adds new points.  The existing points also wander around.
50
51 There are a set of control points on the plane, each at the center of
52 a colored cell.  Every pixel within that cell is closer to that cell's
53 control point than to any other control point.  That is what
54 determines the cell's shapes.
