I´ll shamelessly post in this thread, since my suggestion follows up with what has been discussed here

I have the scenario that I need the entire page of a magazine to be clickable, since link areas can happen to be anywhere across the page, even in the corners.
My idea was to move the hitarea off the page. The ePaper implementation here demonstrates what I´m aiming at:

Adding a configurable offset to the hitareas would be a good idea I think.
I´m looking at implementing it myself, I believe the object I´m needing to look at is the DragHandler?
Really great project you are having here by the way, I looked at various commercial solutions and they often didn´t have half the features your project has!
