// For use with SWFObject by Geoff Stearns
//
// Usage:
//
// -Import this script into the head of your document
// -Set up SWFObject as per the documentation. In the example below, the 'holder' DIV has an id "flashmovie"
// -Change the inline script from:
//
//			var so = new SWFObject("someswf.swf", "mymovie", "300", "300", "8", "#dddddd");
//			so.write("flashmovie");
//
//		-to-
//
//			var so = new SWFObject("someswf.swf", "mymovie", "300", "300", "8", "#dddddd");
//			var soResizer = new SWFObjectResizer("flashmovie",so);
//			so.write(soResizer.getElementId()); //no longer "flashmovie" but auto-generated by SWFObjectResizer
//
// The dimensions of the SWFObject are in pixels (but do not append "px")
//
// To resize the player so the HTML document does not reflow (i.e. floating player)
//
//			soResizer.resize(600,600,true);
//
// or change the last parameter to false to cause the page to reflow (i.e. inline player)
//
// To revert the player to its original position call:
//
//			soResizer.revert()
//
// These methods can also be called from ActionScript:
//
//			ExternalInterface.call("soResizer.resize",600,600,true);
// -and-
//			ExternalInterface.call("soResizer.revert");
//
//
// There is a bug with Opera 9 and Flash Player 9.0.16.0 that slows ExternalInterface calls down to a crawl
// it does not occur using Flash Player 8.0.24.0
