	// description:
	//		A Simple FisheyeList-like widget which (in the interest of
	//		performance) relies on well-styled content for positioning,
	// 		and natural page layout for rendering.
	//
	//		use position:absolute/relative nodes to prevent layout
	//		changes, and use caution when seleting properties to
	//		scale. Negative scaling works, but some properties
	//		react poorly to being set to negative values, IE being
	//		particularly annoying in that regard.
	//
	//		quirk: uses the domNode as the target of the animation
	//		unless it finds a node class="fisheyeTarget" in the container
	//		being turned into a FisheyeLite instance
	//
	// example:
	//	|	// make all the LI's in a node Fisheye's:
	//	|   dojo.query("#node li").forEach(function(n){
	// 	|		new dojox.widget.FisheyeLite({},n);
	//	|	});
	//
