Callback from {@link com.jme3.util.clone.Cloner} to convert this
shallow-cloned Control into a deep-cloned one, using the specified Cloner
and original to resolve copied fields.

@param cloner the Cloner that's cloning this Control (not null, modified)
@param original the instance from which this Control was shallow-cloned
(not null, unaffected)
