[TIMOB-8778] MobileWeb: Queue up touch/mouse events and process and a slower frequency than realtime

Right now events are processed immediately, but since events (i.e. touchmove events) can fire faster than the eye can perseve, it makes no sense to process the events right away. Instead, the gesture system should queue up touch events, then process them all at once. This interval should perhaps be 30 times per second. This can be done with a setInterval(), but might be better to use requestAnimationFrame() if there is enough browser support.
