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
