Detailed Description

Serializes a GraphicElement to/from a versioned QDataStream.

Extracted from GraphicElement so persistence is a collaborator rather than a cluster of methods on the element itself. A friend of GraphicElement, it reaches the element's ports/orientation/appearance/context-directory state through that friendship. The element keeps thin virtual save()/load() entry points that delegate here, so subclasses (e.g. IC) can still extend the load via their override. All methods are static and take the element explicitly; no serializer instance state is needed.
