An item in your inventory references an asset - it isn't an asset
itself. Any number of inventory items can reference the same asset.
For an example of where it gets complicated, if you have a texture in
your inventory, apply the texture to a face of an object, then delete
and purge the texture from your inventory, the asset is still in use
by that object face. It must not be purged.
