Hiya everyone,

I've written a small wrapper around a Tkinter Canvas which lets people
play around with line drawing.  Once loaded, graphics.py makes a 400x400
canvas and provides global functions to meddle with it.

The graphics.py module is meant to be "from graphics import *"'ed; once
you the import, the following functions become available:

    clearGraphics()
    positionPen(x, y)
    drawLineTo(x, y)
    drawLine(x1, y1, x2, y2)
    drawPoint(x, y)
    clearPoint(x, y)
    graphicsText(text, x, y)
    setRGBColor(r, g, b)

and the included circle.py demonstrates how to use graphics.py's features.  
What's neat about this is that if the user accidently closes the Canvas,
calling any of the above functions should magically sprout a new Canvas
without prompting.

I'd like some suggestions on this; I want to make sure that this thing is
useful for people.
