Title: [WIP] Standardize mouse interaction events

I have changed the drag events to use pageX/pageY because they are more common.

There is another issue with zooming with the mouse wheel that I haven't fixed yet. Firefox doesn't support the `mousewheel` event. Also, the meaning of the delta values returned by browsers is different. I would propose using https://github.com/brandonaaron/jquery-mousewheel to normalize this rather than trying do so ourselves. Is it okay to bring in this dependency?
