Canvas.py obsolete - why?

[Gregor Lingl]

Hello!

In the Standard Python distribution with
Tkinter there is contained the module
Canvas.py which among other things exports
class definitions for several geometrical
objects as lines, rectangles, arcs etc.

This module starts with the following comment:

# NOTE: This module was an experiment and is now obsolete.
# It's best to use the Tkinter.Canvas class directly.

Does anyone know, *why* this module is declared
obsolete? (I consider it pretty useful.)
