Comment 9 for bug 1072920

The randr plugin in gnome-settings-daemon sets the Axes Swap and Axis Inversion xinput properties to adjust pointer coordinates.
These two are however ignored by evdev in case of the Nexus (or all touchscreens for that matter)
Upstream's suggestion is to use the Coordinate Transform Matrix property instead in that plugin, the same used in the xrotate and acceld scripts in our nexus 7 image.
