Issue 6: All functions should have callback hooks and trigger events
Project Member Reported by jeremyck...@gmail.com, Jun 29, 2010
It would be useful if the JCK was throughly extensible by user-defined callback functions.  It would also be useful if many of the functions triggered a corresponding event.  For example:

canvas.togglePause(userFunc);

and if calling the above function triggered an event.
