Use case: Show information on historic maps

Feature

Specify a commons image to show as map background, e.g. https://commons.wikimedia.org/wiki/File:Mitchell_Map-06full2.jpg

Requirements

Requires the map on commons to schematically be tagged with bounding box and orientation.

Good support with different zoom levels likely requires IIIF support in Commons.
