Steps to reproduce this issue on a single monitor setup with Ubuntu 13.04 and
Mesa 9.2.0:

* Open any window, and move it close to the bottom of the screen (this makes
the bug more apparent)
* Get the window's XID with xwininfo
* run:  gst-launch-1.0 ximagesrc xid=$WINDOW_XID ! ximagesink
* Bring the window to focus and move the mouse cursor across it slowly in some
pattern

Expected behavior:
* The position of the GStreamer mouse relative to the window should be the same
as the real mouse.

Actual behavior:
* GStreamer mouse is offset vertically by a number of pixels corresponding to
the distance of the window from the top of the screen.
