		De la documentacion de jQuery:
		
		Because of the nature of requestAnimationFrame(), 
		you should never queue animations using a setInterval or 
		setTimeout loop. In order to preserve CPU resources, 
		browsers that support requestAnimationFrame will not 
		update animations when the window/tab is not displayed. 
		If you continue to queue animations via setInterval or 
		setTimeout while animation is paused, all of the queued 
		animations will begin playing when the window/tab regains 
		focus. To avoid this potential problem, use the callback 
		of your last animation in the loop, or append a function 
		to the elements .queue() to set the timeout to start the 
		next animation.
