3Optional properties for Touchscreens:
4 - touchscreen-min-x		: minimum x coordinate reported (0 if not set)
5 - touchscreen-min-y		: minimum y coordinate reported (0 if not set)
6 - touchscreen-size-x		: horizontal resolution of touchscreen
7				  (maximum x coordinate reported + 1)
8 - touchscreen-size-y		: vertical resolution of touchscreen
9				  (maximum y coordinate reported + 1)
10 - touchscreen-max-pressure	: maximum reported pressure (arbitrary range
11				  dependent on the controller)
12 - touchscreen-fuzz-x		: horizontal noise value of the absolute input
13				  device (in pixels)
14 - touchscreen-fuzz-y		: vertical noise value of the absolute input
15				  device (in pixels)
16 - touchscreen-fuzz-pressure	: pressure noise value of the absolute input
17				  device (arbitrary range dependent on the
18				  controller)
19 - touchscreen-average-samples : Number of data samples which are averaged
20				  for each read (valid values dependent on the
21				  controller)
22 - touchscreen-inverted-x	: X axis is inverted (boolean)
23 - touchscreen-inverted-y	: Y axis is inverted (boolean)
24 - touchscreen-swapped-x-y	: X and Y axis are swapped (boolean)
25				  Swapping is done after inverting the axis
26 - touchscreen-x-mm		: horizontal length in mm of the touchscreen
