// A simple Turtle graphics example.
// Created by Lyn, 3/14/97
// Updated 11/3/97
// Simplified by Randy for CS111 presentation 4/5/05
// Safari bug fixed:  Used to use currentWorld.getGraphics() to set up turtleGraphics.
// This stored a graphics object that always returned null for getClipBounds().  Storing
// the graphics object passed to paint() fixed it.  -Mark 6 Dec 2005
