Detailed Description

Maps an entity id stored on the map to a GRF file.

Entities are objects used ingame (houses, industries, industry tiles) for which we need to correlate the ids from the grf files with the ones in the the savegames themselves. An array of EntityIDMapping structs is saved with the savegame so that those GRFs can be loaded in a different order, or removed safely. The index in the array is the entity's ID stored on the map.

The substitute ID is the ID of an original entity that should be used instead if the GRF containing the new entity is not available.
