When you say 'activate' I suspect this means that you
add the listeners to the canvas.

I think you end up registering a new instance of the
listeners when the user clicks 'polygon'. You either need
to only register them once (and have a way to disable them
when they shouldn't do anything), or remove them after the
polygon is created.

Does this get printed twice for each point, like:
156,402 156,402 304,170
156,402 156,402 304,170 304,170
I suspect you need to call 'EventTarget.removeEventListener'
