	// description:
	//	The goal of dojox.flash is to make it easy to extend Flash's capabilities
	//	into an AJAX/DHTML environment. Robust, performant, reliable
	//	JavaScript/Flash communication is harder than most realize when they
	//	delve into the topic, especially if you want it
	//	to work on Internet Explorer, Firefox, and Safari, and to be able to
	//	push around hundreds of K of information quickly. dojox.flash makes it
	//	possible to support these platforms; you have to jump through a few
	//	hoops to get its capabilites, but if you are a library writer
	//	who wants to bring Flash's storage or streaming sockets ability into
	//	DHTML, for example, then dojox.flash is perfect for you.
	//
	//	dojox.flash provides an easy object for interacting with the Flash plugin.
	//	This object provides methods to determine the current version of the Flash
	//	plugin (dojox.flash.info); execute Flash instance methods
	//	independent of the Flash version
	//	being used (dojox.flash.comm); write out the necessary markup to
	//	dynamically insert a Flash object into the page (dojox.flash.Embed; and
	//	do dynamic installation and upgrading of the current Flash plugin in
	//	use (dojox.flash.Install).
	//
	//	To use dojox.flash, you must first wait until Flash is finished loading
	//	and initializing before you attempt communication or interaction.
	//	To know when Flash is finished use dojo.connect:
	//
	//	dojo.connect(dojox.flash, "loaded", myInstance, "myCallback");
	//
	//	Then, while the page is still loading provide the file name
	//	and the major version of Flash that will be used for Flash/JavaScript
	//	communication (see "Flash Communication" below for information on the
	//	different kinds of Flash/JavaScript communication supported and how they
	//	depend on the version of Flash installed):
	//
	//	dojox.flash.setSwf({flash6: dojo.moduleUrl("dojox", "_storage/storage_flash6.swf"),
	//						flash8: dojo.moduleUrl("dojox", "_storage/storage_flash8.swf")});
	//
	//	This will cause dojox.flash to pick the best way of communicating
	//	between Flash and JavaScript based on the platform.
	//
	//	If no SWF files are specified, then Flash is not initialized.
	//
	//	Your Flash must use DojoExternalInterface to expose Flash methods and
	//	to call JavaScript; see "Flash Communication" below for details.
	//
	//	setSwf can take an optional 'visible' attribute to control whether
	//	the Flash object is visible or not on the page; the default is visible:
	//
	//	dojox.flash.setSwf({flash6: dojo.moduleUrl("dojox", "_storage/storage_flash6.swf"),
	//						flash8: dojo.moduleUrl("dojox", "_storage/storage_flash8.swf"),
	//						visible: false });
	//
	//	Once finished, you can query Flash version information:
	//
	//	dojox.flash.info.version
	//
	//	Or can communicate with Flash methods that were exposed:
	//
	//	var results = dojox.flash.comm.sayHello("Some Message");
	//
	//	Only string values are currently supported for both arguments and
	//	for return results. Everything will be cast to a string on both
	//	the JavaScript and Flash sides.
	//
	//	-------------------
	//	Flash Communication
	//	-------------------
	//
	//	dojox.flash allows Flash/JavaScript communication in
	//	a way that can pass large amounts of data back and forth reliably and
	//	very fast. The dojox.flash
	//	framework encapsulates the specific way in which this communication occurs,
	//	presenting a common interface to JavaScript irrespective of the underlying
	//	Flash version.
	//
	//	There are currently three major ways to do Flash/JavaScript communication
	//	in the Flash community:
	//
	//	1) Flash 6+ - Uses Flash methods, such as SetVariable and TCallLabel,
	//	and the fscommand handler to do communication. Strengths: Very fast,
	//	mature, and can send extremely large amounts of data; can do
	//	synchronous method calls. Problems: Does not work on Safari; works on
	//	Firefox/Mac OS X only if Flash 8 plugin is installed; cryptic to work with.
	//
	//	2) Flash 8+ - Uses ExternalInterface, which provides a way for Flash
	//	methods to register themselves for callbacks from JavaScript, and a way
	//	for Flash to call JavaScript. Strengths: Works on Safari; elegant to
	//	work with; can do synchronous method calls. Problems: Extremely buggy
	//	(fails if there are new lines in the data, for example); performance
	//	degrades drastically in O(n^2) time as data grows; locks up the browser while
	//	it is communicating; does not work in Internet Explorer if Flash
	//	object is dynamically added to page with document.writeln, DOM methods,
	//	or innerHTML.
	//
	//	3) Flash 6+ - Uses two seperate Flash applets, one that we
	//	create over and over, passing input data into it using the PARAM tag,
	//	which then uses a Flash LocalConnection to pass the data to the main Flash
	//	applet; communication back to Flash is accomplished using a getURL
	//	call with a javascript protocol handler, such as "javascript:myMethod()".
	//	Strengths: the most cross browser, cross platform pre-Flash 8 method
	//	of Flash communication known; works on Safari. Problems: Timing issues;
	//	clunky and complicated; slow; can only send very small amounts of
	//	data (several K); all method calls are asynchronous.
	//
	//	dojox.flash.comm uses only the first two methods. This framework
	//	was created primarily for dojox.storage, which needs to pass very large
	//	amounts of data synchronously and reliably across the Flash/JavaScript
	//	boundary. We use the first method, the Flash 6 method, on all platforms
	//	that support it, while using the Flash 8 ExternalInterface method
	//	only on Safari with some special code to help correct ExternalInterface's
	//	bugs.
	//
	//	Since dojox.flash needs to have two versions of the Flash
	//	file it wants to generate, a Flash 6 and a Flash 8 version to gain
	//	true cross-browser compatibility, several tools are provided to ease
	//	development on the Flash side.
	//
	//	In your Flash file, if you want to expose Flash methods that can be
	//	called, use the DojoExternalInterface class to register methods. This
	//	class is an exact API clone of the standard ExternalInterface class, but
	//	can work in Flash 6+ browsers. Under the covers it uses the best
	//	mechanism to do communication:
	//
	//	class HelloWorld{
	//		function HelloWorld(){
	//			// Initialize the DojoExternalInterface class
	//			DojoExternalInterface.initialize();
	//
	//			// Expose your methods
	//			DojoExternalInterface.addCallback("sayHello", this, this.sayHello);
	//
	//			// Tell JavaScript that you are ready to have method calls
	//			DojoExternalInterface.loaded();
	//
	//			// Call some JavaScript
	//			var resultsReady = function(results){
	//				trace("Received the following results from JavaScript: " + results);
	//			}
	//			DojoExternalInterface.call("someJavaScriptMethod", resultsReady,
	//																	 someParameter);
	//		}
	//
	//		function sayHello(){ ... }
	//
	//		static main(){ ... }
	//	}
	//
	//	DojoExternalInterface adds two new functions to the ExternalInterface
	//	API: initialize() and loaded(). initialize() must be called before
	//	any addCallback() or call() methods are run, and loaded() must be
	//	called after you are finished adding your callbacks. Calling loaded()
	//	will fire the dojox.flash.loaded() event, so that JavaScript can know that
	//	Flash has finished loading and adding its callbacks, and can begin to
	//	interact with the Flash file.
	//
	//	To generate your SWF files, use the ant task
	//	"buildFlash". You must have the open source Motion Twin ActionScript
	//	compiler (mtasc) installed and in your path to use the "buildFlash"
	//	ant task; download and install mtasc from http://www.mtasc.org/.
	//
	//
	//
	//	buildFlash usage:
	//
	//	// FIXME: this is not correct in the 0.9 world!
	//	ant buildFlash -Ddojox.flash.file=../tests/flash/HelloWorld.as
	//
	//	where "dojox.flash.file" is the relative path to your Flash
	//	ActionScript file.
	//
	//	This will generate two SWF files, one ending in _flash6.swf and the other
	//	ending in _flash8.swf in the same directory as your ActionScript method:
	//
	//	HelloWorld_flash6.swf
	//	HelloWorld_flash8.swf
	//
	//	Initialize dojox.flash with the filename and Flash communication version to
	//	use during page load; see the documentation for dojox.flash for details:
	//
	//	dojox.flash.setSwf({flash6: dojo.moduleUrl("dojox", "flash/tests/flash/HelloWorld_flash6.swf"),
	//					 	flash8: dojo.moduleUrl("dojox", "flash/tests/flash/HelloWorld_flash8.swf")});
	//
	//	Now, your Flash methods can be called from JavaScript as if they are native
	//	Flash methods, mirrored exactly on the JavaScript side:
	//
	//	dojox.flash.comm.sayHello();
	//
	//	Only Strings are supported being passed back and forth currently.
	//
	//	JavaScript to Flash communication is synchronous; i.e., results are returned
	//	directly from the method call:
	//
	//	var results = dojox.flash.comm.sayHello();
	//
	//	Flash to JavaScript communication is asynchronous due to limitations in
	//	the underlying technologies; you must use a results callback to handle
	//	results returned by JavaScript in your Flash AS files:
	//
	//	var resultsReady = function(results){
	//		trace("Received the following results from JavaScript: " + results);
	//	}
	//	DojoExternalInterface.call("someJavaScriptMethod", resultsReady);
	//
	//
	//
	//	-------------------
	//	Notes
	//	-------------------
	//
	//	If you have both Flash 6 and Flash 8 versions of your file:
	//
	//	dojox.flash.setSwf({flash6: dojo.moduleUrl("dojox", "flash/tests/flash/HelloWorld_flash6.swf"),
	//					 	flash8: dojo.moduleUrl("dojox", "flash/tests/flash/HelloWorld_flash8.swf")});
	//
	//	but want to force the browser to use a certain version of Flash for
	//	all platforms (for testing, for example), use the djConfig
	//	variable 'forceFlashComm' with the version number to force:
	//
	//	var djConfig = { forceFlashComm: 6 };
	//
	//	Two values are currently supported, 6 and 8, for the two styles of
	//	communication described above. Just because you force dojox.flash
	//	to use a particular communication style is no guarantee that it will
	//	work; for example, Flash 8 communication doesn't work in Internet
	//	Explorer due to bugs in Flash, and Flash 6 communication does not work
	//	in Safari. It is best to let dojox.flash determine the best communication
	//	mechanism, and to use the value above only for debugging the dojox.flash
	//	framework itself.
	//
	//	Also note that dojox.flash can currently only work with one Flash object
	//	on the page; it and the API do not yet support multiple Flash objects on
	//	the same page.
	//
	//	We use some special tricks to get decent, linear performance
	//	out of Flash 8's ExternalInterface on Safari; see the blog
	//	post
	//	http://codinginparadise.org/weblog/2006/02/how-to-speed-up-flash-8s.html
	//	for details.
	//
	//	Your code can detect whether the Flash player is installing or having
	//	its version revved in two ways. First, if dojox.flash detects that
	//	Flash installation needs to occur, it sets dojox.flash.info.installing
	//	to true. Second, you can detect if installation is necessary with the
	//	following callback:
	//
	//	dojo.connect(dojox.flash, "installing", myInstance, "myCallback");
	//
	//	You can use this callback to delay further actions that might need Flash;
	//	when installation is finished the full page will be refreshed and the
	//	user will be placed back on your page with Flash installed.
	//
	//	-------------------
	//	Todo/Known Issues
	//	-------------------
	//
	//	There are several tasks I was not able to do, or did not need to fix
	//	to get dojo.storage out:
	//
	//	* When using Flash 8 communication, Flash method calls to JavaScript
	//	are not working properly; serialization might also be broken for certain
	//	invalid characters when it is Flash invoking JavaScript methods.
	//	The Flash side needs to have more sophisticated serialization/
	//	deserialization mechanisms like JavaScript currently has. The
	//	test_flash2.html unit tests should also be updated to have much more
	//	sophisticated Flash to JavaScript unit tests, including large
	//	amounts of data.
	//
	//	* On Internet Explorer, after doing a basic install, the page is
	//	not refreshed or does not detect that Flash is now available. The way
	//	to fix this is to create a custom small Flash file that is pointed to
	//	during installation; when it is finished loading, it does a callback
	//	that says that Flash installation is complete on IE, and we can proceed
	//	to initialize the dojox.flash subsystem.
