// 2007-10-16:  Note from Alan Cobb: www.alancobb.com
//
//	This is a reformatted version of Silverlight.js from the 
//	2007-09 v1.0 Silverlight SDK.  The stock Silverlight.js 
//	comes as a single line of Javascript 7000+ characters
//	long.  This version was reformatted to allow easier 
//	debugging and single stepping.  It should not be used in 
//	production code, but I don't think it violates the 
//	Silverlight license, because it does not modify any of 
//	the actual code, just the formatting.
//
//	To do this reformatting, I first used a trial copy of 
//	Polystyle: http://www.polystyle.com/, then I added 
//	lines of '*' to more visibly separate the functions.
