//
//  SWFDisplayItem Class
//	item/symbol in movie which can be manipulated
//
//  Notes
//    -	one manipulates these items to set the scene and then writes
//	the frame.  This is how animation is accomplished
//
//    -	the user doesn't instantiate this object, it is rather generated
//	by other interfaces.  Hence the constructor will be private
