/******************************************************************************
 *	Notes about dojo.io design:
 *	
 *	The dojo.io.* package has the unenviable task of making a lot of different
 *	types of I/O feel natural, despite a universal lack of good (or even
 *	reasonable!) I/O capability in the host environment. So lets pin this down
 *	a little bit further.
 *
 *	Rhino:
 *		perhaps the best situation anywhere. Access to Java classes allows you
 *		to do anything one might want in terms of I/O, both synchronously and
 *		async. Can open TCP sockets and perform low-latency client/server
 *		interactions. HTTP transport is available through Java HTTP client and
 *		server classes. Wish it were always this easy.
 *
 *	xpcshell:
 *		XPCOM for I/O. A cluster-fuck to be sure.
 *
 *	spidermonkey:
 *		S.O.L.
 *
 *	Browsers:
 *		Browsers generally do not provide any useable filesystem access. We are
 *		therefore limited to HTTP for moving information to and from Dojo
 *		instances living in a browser.
 *
 *		XMLHTTP:
 *			Sync or async, allows reading of arbitrary text files (including
 *			JS, which can then be eval()'d), writing requires server
 *			cooperation and is limited to HTTP mechanisms (POST and GET).
 *
 *		<iframe> hacks:
 *			iframe document hacks allow browsers to communicate asynchronously
 *			with a server via HTTP POST and GET operations. With significant
 *			effort and server cooperation, low-latency data transit between
 *			client and server can be acheived via iframe mechanisms (repubsub).
 *
 *		SVG:
 *			Adobe's SVG viewer implements helpful primitives for XML-based
 *			requests, but receipt of arbitrary text data seems unlikely w/o
 *			<![CDATA[]]> sections.
 *
 *
 *	A discussion between Dylan, Mark, Tom, and Alex helped to lay down a lot
 *	the IO API interface. A transcript of it can be found at:
 *		http://dojotoolkit.org/viewcvs/viewcvs.py/documents/irc/irc_io_api_log.txt?rev=307&view=auto
 *	
 *	Also referenced in the design of the API was the DOM 3 L&S spec:
 *		http://www.w3.org/TR/2004/REC-DOM-Level-3-LS-20040407/load-save.html

 *	DETECT that you've moved backwards by inspecting window.location.
 *	Unless there is some other means of locating.
 *	FIXME: perhaps we can poll on history.length?
 *  Safari 2.0.3+ (and probably 1.3.2+):
 *	works fine, except when changeUrl is used. When changeUrl is used,
 *	Safari jumps all the way back to whatever page was shown before
 *	the page that uses dojo.undo.browser support.
 *  IE 5.5 SP2:
 *	back button behavior is macro. It does not move back to the
 *	previous hash value, but to the last full page load. This suggests
 *	that the iframe is the correct way to capture the back button in
 *	these cases.
 *	Don't test this page using local disk for MSIE. MSIE will not create 
 *	a history list for iframe_history.html if served from a file: URL. 
 *	The XML served back from the XHR tests will also not be properly 
 *	created if served from local disk. Serve the test pages from a web 
 *	server to test in that browser.
 *  IE 6.0:
 *	same behavior as IE 5.5 SP2
 * Firefox 1.0:
 *	the back button will return us to the previous hash on the same
 *	page, thereby not requiring an iframe hack, although we do then
 *	need to run a timer to detect inter-page movement.

	 * addToHistory takes one argument, and it is an object that defines the following functions:
	 * - To support getting back button notifications, the object argument should implement a
	 *   function called either "back", "backButton", or "handle". The string "back" will be
	 *   passed as the first and only argument to this callback.
	 * - To support getting forward button notifications, the object argument should implement a
	 *   function called either "forward", "forwardButton", or "handle". The string "forward" will be
	 *   passed as the first and only argument to this callback.
	 * - If you want the browser location string to change, define "changeUrl" on the object. If the
	 *   value of "changeUrl" is true, then a unique number will be appended to the URL as a fragment
	 *   identifier (http://some.domain.com/path#uniquenumber). If it is any other value that does
	 *   not evaluate to false, that value will be used as the fragment identifier. For example,
	 *   if changeUrl: 'page1', then the URL will look like: http://some.domain.com/path#page1
	 *   
	 * Full example:
	 * 
	 * dojo.undo.browser.addToHistory({
	 *   back: function() { alert('back pressed'); },
	 *   forward: function() { alert('forward pressed'); },
	 *   changeUrl: true

		Notes:

		General:
			- Uncomputable values are returned as NaN.
			- setOuterWidth/Height return *false* if the outer size could not
			  be computed, otherwise *true*.
			- (sjmiles) knows no way to find the calculated values for auto-margins. 
			- All returned values are floating point in 'px' units. If a
			  non-zero computed style value is not specified in 'px', NaN is
			  returned.

		FF:
			- styles specified as '0' (unitless 0) show computed as '0pt'.

		IE:
			- clientWidth/Height are unreliable (0 unless the object has 'layout').
			- margins must be specified in px, or 0 (in any unit) for any
			  sizing function to work. Otherwise margins detect as 'auto'.
			- padding can be empty or, if specified, must be in px, or 0 (in
			  any unit) for any sizing function to work.

		Safari:
			- Safari defaults padding values to 'auto'.

		See the unit tests for examples of (un)computable values in a given browser.
