Beware of mouseenter. In my experience, when the mouse is moving fast  
mouseenter sometimes doesn't get sent (this ought to be labeled as a  
bug). Mousemove is more reliable, though it will get called  
repeatedly. Unless you are doing something very complex on mousemove,  
however, it won't slow anything down.
