 * SWFMacMouseWheel v2.0: Mac Mouse Wheel functionality in flash - http://blog.pixelbreaker.com/
 *
 * SWFMacMouseWheel is (c) 2007 Gabriel Bucknall and is released under the MIT License:
 * http://www.opensource.org/licenses/mit-license.php
 *
 * Modded by Robert M. Hall - rhall@impossibilities.com
 * Adjusted following functionality:
 * 1. Watch for events related only to flash content and not the container page
 * 2. Fixed to dispatch mousewheel events only to specific intance ID's that were registered, this
 *    allows multiple SWFobject embeds on a page to use swfmacmousewheel and they will only respond
 *    to their specific target ID's when the event.target.is passed. This way only the currently active item will receive a dispatch event.
 * 3. Works with SWFObject 2.1
 * 4. No longer throws an error on IE/PC platforms because of a null object
 * 5. Works on Safari for PC
 *
 * Dependencies:
 * SWFObject v2.1 <http://code.google.com/p/swfobject/>
 * Copyright (c) 2007 Geoff Stearns, Michael Williams, and Bobby van der Sluis
 * This software is released under the MIT License <http://www.opensource.org/licenses/mit-license.php>
 *
 * Requires a few lines of changes to the AS2 and AS3 code to support the PC version of Safari
 * as well as an additional Flashvar paramater, set flashvars.browser = Browser.name;
 * These changes are only required for Safari on PC - all other modifications noted above are contained solely in this JavaScript
 * Safari PC support based on code/suggestions from Richard "RaillKill" Rodney of Hypermedia - http://railkill.free.fr/
 *
 * Browser detect part from http://www.quirksmode.org/js/detect.html
