Description:
 def emulate_wheel(self, data, direction, timeval):
 """Emulate rel values for the mouse wheel. In evdev, a single click forwards of the mouse wheel is 1 and a click back is -1. Windows uses 120 and -120. We floor divide the Windows number by 120. This is fine for the digital scroll wheels found on the vast majority of mice. It also works on the analogue ball on the top of the Apple mouse. What do the analogue scroll wheels found on 200 quid high end gaming mice do? If the lowest unit is 120 then we are okay. If they report changes of less than 120 units Windows, then this might be an unacceptable loss of precision. Needless to say, I don't have such a mouse to test one way or the other. """
