iOS6 webkit timer bug workaround

	(function (window) {
	// This library re-implements setTimeout, setInterval, clearTimeout, clearInterval for iOS6.
	// iOS6 suffers from a bug that kills timers that are created while a page is scrolling.
	// This library fixes that problem by recreating timers after scrolling finishes (with interval correction).
	// This code is free to use by anyone (MIT, blabla).
	// Original Author: [email protected]
	var timeouts = {};
	var intervals = {};
	var orgSetTimeout = window.setTimeout;
	var orgSetInterval = window.setInterval;

JavaScript techniques including bitwise operator replacement techniques, shortcuts, etc.

	var PI = Math.PI;

	//Faster replacement for Math object methods.
	Math.round(PI) === PI + (PI < 0 ? -0.5 : +0.5) >> 0;
	Math.ceil(PI) === PI + (PI < 0 ? -1 : 0) >> 0;
	Math.floor(PI) === PI + (PI < 0 ? -1 : 0) >> 0;

	//Conditional operator is faster than Math object methods.
	Math.max(a, b) === (a > b) ? a : b;
	Math.min(a, b) === (a < b) ? a : b;

iOS 6 timer bug test sample. Apparently, Apple fixed the problem on iOS 6.1.

	<!DOCTYPE html>
	<html>

	<head>
	<meta name="viewport" content="width=device-width, minimum-scale=1.0, maximum-scale=1.0, user-scalable=no">
	<script>
	window.onload = function() {
	var element = document.getElementById("test");
	var result = document.getElementById("result");
	var count = 0;
