In some cases items render their children directly using an effect. In this case we do not want to hide the children when calling refFromEffectItem(). If the hint takesOverRenderingOfChildren is set in the .metainfo hints for a parent item we forward a flag to the puppet and refFromEffectItem() is not hiding this item, Change-Id: I37a8c0ad8a15bc914c220e03b1b744779431d655 Reviewed-by: Alessandro Portale <alessandro.portale@qt.io>
