Some kobo touch devices have X Y coordinates in touch events swapped. This patch provides a GUI to probe if the device needs to swap the XY. The Kobo Touch users will be directed to tap on the upper right corner of the screen and the probe will check if the X value is smaller than the Y value in the tap event.
