eGalax touchscreen calibration

[brantje]

Yea, that where the 4px.
I didn't need the - sign i removed them.

Also modified the input-create.py abit to squeeze the bug i mentioned.

Code:

if inrange <= 400:
            if holdtime > 0.20 and holdtime <= 0.50:
                rev.code = BTN_TOUCH
                rev.value = 1
                d.fire_event(rev)
                rev.value = 0
                d.fire_event(rev)
            if holdtime > 0.50 and holdtime <= 1.50:
                rev.code = BTN_RIGHT
                rev.value = 1
                d.fire_event(rev)
                rev.value = 0
                d.fire_event(rev)
            if holdtime > 1.5:
                rev.code = BTN_TOUCH
                rev.value = 1
                d.fire_event(rev)
                rev.value = 0
                d.fire_event(rev)

This prevents going back when in a list using the scrollbar
