Patch by Robert Kroeger <rjkroege@chromium.org> on 2011-08-02
Reviewed by Adam Barth.

Divided the gesture recognizer up to correct a layering
violation by moving gesture implementation from it to
EventHandler::handleGestureEvent so that the gesture recognizer
could simply be an engine for generating gesture events from
touch events.

Moved gesture recognition higher up the event delivery code
path so that recognition of gestures is completely separated
from gesture handling.
