eGalax touchscreen calibration

[Markamc]

I am guessing this is a result of applying the new egalax patch from Andrei.

I believe the new patch solves the original 'single touch' (mousedrag) inside the xbmc code. I was forcing an extra event outside xbmc and controlling BTN_RIGHT/calibration.

Maybe others prefer it, but it means a 'touch press' now 'actions' a button immediately; it would be nice to include tiny a delay, to prevent accessing everything with a touch. For example, normal behavior on selecting the outermost item(left/right) would scroll the menu, now it accesses the item. Maybe Andrei could sort this??
