* Canvas Events class extends canvas object to help to attach mouse events
* to different shapes with minimal javascript code modifications.
* Canvas context methods that perform actual drawing like
* stroke, fill, strokeRect, fillRect, drawImage
* return a shape object to which you can attach events
*
