//ngIcon v0.2. Bta. 16/07/08.
	//Changes from v0.1: getPoint(), getLatLng() functions added for interoperability reasons.
	//Public domain! Free! Etc! It's hardly complicated anyway ;)
	//Known issues: PNG transparency in old browsers. Infowindow is locked to the point (this is, actually, by design, but can be easily modified).
	
	// These really need to be set. You have been warned. NgIcon is designed to be used with 24-bit PNGs for transparency effects.
