[Bf-committers] Border zoom patch

[Emanuel Greisen]

An other feature that would be really nice (not only for zooming, but 
also translation, scaling, rotating etc.) would be a wrapped cursor (I'm 
not much for saying it, but like in 3DS). When you drag to the top of 
your screen, the cursor wraps, and re-appears at the bottom, making it 
possible to make an infinitely long drag, even though your screen has a 
finite size. Ofcause this goes for all border of the screen, not only 
the top :-)
