I do not agree. At least not the kinds I had to do with. The calibration 
can indeed be done in software but usually it is done by a driver 
supplied by the touchscreen maker. The touchscreen looks like a mouse 
and sends a coordinate set (motion) followed by a left click for every 
user touch. Using other functions may require special drivers.
