HID: magicmouse: scroll on entire surface, not just middle of mouse
Previously, scroll events only occurred when the user moved a touch along the middle of the touch surface. This is unintuitive for a normal user who is not aware of this. The device has a uniform surface, so the distinction is artificial. This change removes the touch area check for a scroll event, which replicates the OS X behavior.
