/**
 * Demonstrates use of DynamicPointSetPainter. This painter is useful when painting
 * large sets of points which can change dynamically and must be individually colored.
 * 
 * TrackPainter is another option for painting large numbers of points, but it can only
 * efficiently draw large groups of points with a single color. ShadedPointPainter allows
 * even more control over the coloring of points (via a shader)  but does not allow easy
 * dynamic addition and removal of points.
