The Scale effect scales a target object in the x and y directions around the transform center. A scale of 2.0 means the object has been magnified by a factor of 2, and a scale of 0.5 means the object has been reduced by a factor of 2. A scale value of 0.0 is invalid.

Like all AnimateTransform-based effects, this effect will only work on subclasses of UIComponent and GraphicElement, as these effects depend on specific transform functions in those classes.
