…quired to produce a valid overall Graph if the Graph has been optimized.

Can we know when the subgraph proto needs re-building, so that we avoid it otherwise?

ToGraphProto only rebuilds if it has to. If there have been no changes it will return the currrent GraphProto instead of creating a new one.

This is required to produce a valid overall Graph if the Graph has been optimized. If the GraphProto attribute are not updated
a) the optimizations will be lost from any subgraphs
b) implicit inputs to the subgraphs may be broken by changes to nodes in the parent graph
