I was not able to generate the gestures "pinch" and "expand" on Kobo Aura.

While debugging ```GestureDetector:panState(tev)```  I saw that the TRACK ID never had -1 values .
So back to debugging ```input.lua```.

Now the Kobo Aura can pinch and expand.

fix closing dict window will bookmark current page
use `self.highlight:handleEvent(Event:new("Tap"))` instead of
`self.ui:handleEvent(Event:new("Tap"))` when clearing highlighted
text since Tap event in latter situation will be captured by
the dogear widget.
