proportional dinamic resize

[Nikolajd]

Помогите пожалуста исправить код resize на proportional resize. Вот код и сам флеш:

var defaultTool:TransformTool = new TransformTool();
addChild(defaultTool);

}
 
// changing tools using the toolChange button

}

}
}
 
// event handlers for selecting objects and changing tools
stage.addEventListener(MouseEvent.MOUSE_DOWN, select);
