Talking to roc, event retargeting will be very complex to implement.
To make it simpler for authors and browser vendors, we should not intercept
the events. Instead, just keep sending them to the canvas object but add
the region's ID to it.
If the author wants to do the retargeting, he could easily do this in JS.
