 * change the screen, it simply resets the list of primitives, which can be useful if you want to
 * rebuild the contents of an existing Graphics object.
 *
 * Once a GraphicsGeometry list is built, you can re-use it in other Geometry objects as
 * an optimization, by passing it into a new Geometry object's constructor.  Because of this
