* Horrible workaround here. There is a bug on Win 10: when warping to
* pixel (x = 0, y = 0) the SendInput() below just does not move the
* mouse pointer. However, as soon as dx or dy is non zero it moves as
* expected. Given the scaling factor of 65535 (see above),
* (dx = 1 , dy = 0) still means pixel (x = 0, y = 0).
* See ticket [69b48f427e].
