H2SWF by Mattias Gunneras 


sIFR inspired heading to swf with blocking.

TODO:
	- Automatically set width and hight of the element.
	
Dependencies:
	- jQuery 1.3
	- swfobject 2


Example Usage:

$('h1').h2swf({
	debug : 0,						// depends on console.log
	alpha : .3,						// blocking transparency
	blocking : [8, 15, 8, 10],		// blocking [top, right, bottom, left]
	leading : -8,					// line spacing
	tracking : -5,					// letter spacing
	pad_desc : 2,					// adds extra blocking on last line if that line's letters has descenders
	background_color : '000000',
	color : 'ffffff',
	font_size : 70,
	sharpness : 0,					
	thickness : 0,					
	swf : "../flash/header.swf",	// path to the swf
	height: 'callback',				// number or 'callback'
	width: 'callback',				// number or 'callback'
	prevent_widow : true,			// prevents a single word on last line in some cases.
	width_threshold : 5				// adjusts blocking width if line width difference < 5
});



TODO:

 - Degrade gracefully for non Flash environments.
 - Move settings and callback function into $.h2swf to avoid cluttering global namespace.
 - Adjust blocked lines to be the same width if width difference is less than width_threshold
