    |   This fifth version (5.0) uses a method to "abbreviate" the  |
    |   main drawing code, with co-ordinates as parameters.         |
    |   In addition, it uses calculation and "moves" to make the    |
    |   drawing process more intuitive.                             |
    |                                                               |
