OnChangingNodeAttribute Event
Fired before an attribute of a node is changed. Note for LGSPBackend: Because graph elements of the LGSPBackend don't know their graph a call to LGSPGraphElement.SetAttribute will not fire this event. If you use this function and want the event to be fired, you have to fire it yourself using ChangingNodeAttributes.
