I'd be lying if I said I saw the point.  If moving the mouse off-screen
is a use case we want to support, why do we currently clamp it to the
screen limits on single screens; why do we clamp it to the extents of
multi-screen setups?  I just don't see why it's necessary to be able to
move the mouse into a specific dead area within the extents but outside
all visible screens.
