eGalax touchscreen calibration

I know we all know this, but ....as xbmc is primarily for mouse control, the touch screen works as a mouse, an absolute mouse. So it is unlikely to hit the same place twice accurately (within a confines limit)

Having played with this before unsuccessfully, I decided to try again; after the changes made for 12.2 and 13 in the MouseStat.cpp file (xbmc git).

Just compiled 12.2 again, having changed click confines values in MouseStat.h from click_confines =7 to click_confines=50. This seems to work like my touchpad and mouse now, more forgiving, allowing me to move to a focus and single click to action.

For reference I have a 7" touchscreen, no need to double click, you can single-tap the focused button without the need to double-click.

This value should really depend on screen-size : finger ratio, for touchscreen, not important for accurate mouse....need proper coding, maybe in 13 final?

Will work to in Beta1 - hopefully
