- rephrase error conditions to be simpler
- reword the matrix description in 'save' request
- rephrase when touch_device events are sent
- change device id to DEVPATH with "/sys" prefix
- qualify calibration units better
- replace wrong_touch event with a more generic invalid_touch
- fix error enum and add bad_coordinates
- convert while cancelled will not raise any errors
