Friendly ping: There are changes requested in order for this patch to land.

We should note that ISO 22028-5 is not a freely available specification. It costs 128 swiss francs. However, it is pretty much an interoperability profile of ITU BT.2100-2 plus a reference display, reference viewing conditions, and mandated MDCV metadata. ISO 22028-5 explicitly does not define what you do with the metadata.

Adding a comment from our meeting today: The dWLm chunk is for Fourth Edition, not Third. So this pull request is being delayed until Third Edition is wrapped up. (We could maintain a separate branch but this is the easier path for now.)

I think that account is a bot. Gonna sleep on it then probably delete it's comments.
