 ** of the different fonts horizontally, and to give each        
 ** a different color. Make sure to check out SimpleApplet3 
 ** first, which shows how to do these things.  Also, edit 
 ** MyApplet6.html in the  project directory, to run the
 ** MyApplet6.class file you create, and to look nice.   **/
