Touch and Gestures for Web Apps

Is there a way to create web apps with the Encapsulator that can use the touch and gestures (zoom, pan, pinch)? My web browser app works well with the IE 10 gestures, but when I create an Appup with the Encapsulator, those don't seem to work.
Is there something I can do in Javascript ?

Can there be TRUE FULLSCREEN in the Encapsulator? the API for fullscreen just maximizes the window.

thanks in advance,
Rodica
