public function calculateScaleRatioToFill(originalWidth:Number, originalHeight:Number, targetWidth:Number, targetHeight:Number):Number|  Product Version :  | Feathers 1.0.0 | 
	 Calculates a scale value to maintain aspect ratio and fill the required
	 bounds (with the possibility of cutting of the edges a bit).
	 
	 
 Parameters 
 | originalWidth:Number | 
|   | 
 | originalHeight:Number | 
|   | 
 | targetWidth:Number | 
|   | 
 | targetHeight:Number | 
Returns public function calculateScaleRatioToFit(originalWidth:Number, originalHeight:Number, targetWidth:Number, targetHeight:Number):Number|  Product Version :  | Feathers 1.0.0 | 
	 Calculates a scale value to maintain aspect ratio and fit inside the
	 required bounds (with the possibility of a bit of empty space on the
	 edges).
	 
	 
 Parameters 
 | originalWidth:Number | 
|   | 
 | originalHeight:Number | 
|   | 
 | targetWidth:Number | 
|   | 
 | targetHeight:Number | 
Returns public function getDisplayObjectDepthFromStage(target:DisplayObject):int|  Product Version :  | Feathers 1.0.0 | 
	 Calculates how many levels deep the target object is on the display list,
	 starting from the Starling stage. If the target object is the stage, the
	 depth will be 0. A direct child of the stage will have a
	 depth of 1, and it increases with each new level. If the
	 object does not have a reference to the stage, the depth will always be
	 -1, even if the object has a parent.
	 
	 
 Parameters 
Returns public function nativeToGlobal(nativePosition:Point, starling:Starling = null, result:Point = null):Point|  Product Version :  | Feathers 3.5.0 | 
	 Converts from native coordinates to Starling global coordinates.
	 
	 
 Parameters 
 | nativePosition:Point | 
|   | 
 | starling:Starling (default = null) | 
|   | 
 | result:Point (default = null) | 
Returns public function stageToStarling(stage:Stage):Starling|  Product Version :  | Feathers 2.2.0 | 
	 Finds the Starling instance that controls a particular
	 starling.display.Stage.
	 
	 
 Parameters 
Returns
