imageAssetMigrations

The image asset's props migrations.

Empty, under mocanvas's own prefix. Empty because the props have not changed since they were first written, and present anyway because the first change needs a numbered sequence to go into — inventing one later, after documents have been saved, is what makes a migration line unrecoverable.

retroactive: false for the same reason: an empty sequence must not claim that documents written before it existed need migrating.
