The new API is added to SugarExt. Similar to the
KeyGrabber we listen on the root window for the
events. We then filter for gestures recognized by
an event controller.
You can add any event controller of the ones recently
added to the toolkit to be tracked and can pass a
specific area where the starting point of the gesture
should be, it's then allowed to go out of bounds as
it moves.
