Script Summary: Instantly scrolls to position determined by mousewheel turns.
Have you ever tried to scroll down a page faster than your browser/computer can handle? You quickly flick the mouse wheel a few times, and when you are done the browser is still trying to catch up. It moves a few lines at a time until it eventually gets where you want it.
InstaScroll solves this problem. If the browser has fallen behind, InstaScroll causes it to instantly move to the accumulated scroll position all at once, instead of performing multiple moves of a few lines at a time.
Major update with version 2.0
Should now properly support textareas, divs, and other things that can possibly have scrollbars.
Also added some code for more instant updates when scrolling all the way to bottom or top of page.
Please let me know if you find any bugs with this script.
