/******************************************************************************
 *	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

	Notes:

	General:
		- Uncomputable values are returned as NaN.
		- setOuterWidth/Height return *false* if the outer size could not be computed, otherwise *true*.
		- I (sjmiles) know 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.
