General Touchscreen Properties:
Optional properties for Touchscreens:
- touchscreen-min-x : minimum x coordinate reported (0 if not set)
- touchscreen-min-y : minimum y coordinate reported (0 if not set)
- touchscreen-size-x : horizontal resolution of touchscreen
(in pixels)
(maximum x coordinate reported + 1)
- touchscreen-size-y : vertical resolution of touchscreen
(in pixels)
(maximum y coordinate reported + 1)
- touchscreen-max-pressure : maximum reported pressure (arbitrary range
dependent on the controller)
- touchscreen-fuzz-x : horizontal noise value of the absolute input
