Validate changes to 2D diagrams

[blakesweeney]

We should ensure we do not lose important diagrams with this rescan. Since our widget is used in other sites we should not lose their diagrams. These sites are:

• Flybase
• SGD
• PDBe

So we should check the new diagrams and ensure we did not lose any diagrams for those resources. If we did, then we have to verify why manually.
