To be able to fix the cursors jumps that we see with any regular image sensor touchpad, I cleaned up all the code and relied on the kernel tracking to provide an actual tracking. So now, either the touchpad is old and it does forwards SEMI_MT, either it is new enough and uses the in-kernel tracking.
