/*
	Object			: Javascript document - 24/32 bit PNG graphics transparency for IE6...
	Developer		: Philippe Marechal
	Date			: 12 july 08
	Notes			: Dependent on "Prototype JavaScript framework (1.6.0)". Works on *img elements* and on *background images of 		
					  elements. PNG's can be used as backgrounds. However, image tiling will not work.
 					  Background PNG's used in :hover's might need another application of the method
	Example Usages	: $('yourPNG').pngHack(); or $$('div#fixMe','img#andMe','img.andUsTo').invoke('pngHack');
