For the most basic case, the GR will recognize gestures and do what?.. it will at the very least need to pass it to the event handler to process the gesture (EventHandler dependency). Also, parameters for some gestures are dependent on the DOM. Take for example, a double-tap-to-zoom gesture. The parameters such as how much to zoom and what to bring to focus can only be obtained from the DOM. This information is also platform specific because different platforms may want to have different interpretation of the gesture.
