Description
In some use cases SetTransform() will be called repeatedly (eg during an interactive gizmo edit). External code may know and/or need to know when such a sequence starts/ends. The OnBeginTransformEdit/OnEndTransformEdit delegates can provide these notifications, however client code must call BeginTransformEditSequence()/EndTransformEditSequence() to fire those delegates as the TransformProxy doesn't know about this external state.
FTransformProxyChangeSource will call these functions on Begin/End
