tdemo_paint.py

A simple  event-driven paint program

- left mouse button moves turtle
- middle mouse button changes color
- right mouse button toggles between pen up
(no line drawn when the turtle moves) and
pen down (line is drawn). If pen up follows
at least two pen-down moves, the polygon that
includes the starting point is filled.
 -------------------------------------------
 Play around by clicking into the canvas
 using all three mouse buttons.
 -------------------------------------------
          To exit press STOP button
