Comment(by Treviño):

 I've just tested this patch and the touchscreen implementation in stable-
 tracking now seems a little better than the previous one, but it's still
 buggy (and quite far from the latest stable implementation).

 The main bug I've found in my first test (mostly done writing on illume
 keyboard and using the tick's touch screen test pyhton app) is that quite
 often happens that the touchscreen send a "push" event to the gui also if
 I've no finger over it (practically the release event is not sent!).

 I got also other errors while scrolling the illume desktop (some
 applications started while I was still dragging my finger and keep in mind
 that I've configured illume to start an application only after a double-
 click! So the touchscreen has sent more than a wrong click).

 Up-down-clicks are not always fixed, btw... :(
