Release is not a problem when the "press" finally has gone through.
It's just that I want to make a BUTTON_DOWN event when I get a touch
event from my touchscreen driver.
Other drivers seems to spit out alot of data when holding the finger
down, so if first event is dropped it won't be noticed since next one is
comming so fast.
My driver doesn't work that way. Might this be the problem?
