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