The reason for the change was that I usually have many applications with 
a scrollbar left or right, often near a desk edge.
It was (particularly when using a theme with 1 pixel left/right window 
borders) very easy to accidentally scroll in the edge window instead of 
in the application scrollbar, annoyingly flipping the desk instead of 
scrolling the application pane.

I have pushed a change so that the top/bottom edges now handle button 
press/release events as before, but the left/right ones still don't.

If you still think it should be configurable we can do that, but I'd 
prefer not to have yet another semi-obscure setting.

Thanks :)
