Bug Description

[Impact]

coordinate mapping is off when using a transformation matrix, needs an upstream patch to fix

[Test case]

1. Boot into Ubuntu 12.04.2 live system

2. Expand the laptop display to the external one.
For example, `xrandr --output eDP1 --auto --output HDMI1 --auto --right-of eDP1`

3. Restrict the movements of the touchscreen to the laptop display.
For example, `xinput map-to-crtc 'ELAN Touchscreen' eDP1`

P.S. `xinput map-to-crtc` will calculate and set "Coordinate Transformation Matrix" correspondingly.

= Expected Result =

I can operate the touchscreen on the laptop display as usual.

= Actual Result =

It becomes abnormal and shows erratic cursor movement.

P.S. Ubuntu 13.04 is OK.

[Regression potential]

slim, this has been upstream since 1.13.2
