make freehand drawings smoother

Now I might actually use them more, and maybe I can start considering taking out some shapes. Do I really need circles if I don't provide ellipses?

Thanks Ivan Reese for the feedback. "What drawings does your tool encourage?"

Minor note: taking out the deepcopy creates a cute little string like effect, where the curve grows tighter the slower you draw it.
