Cache Key Rules
---------------
* Images in the cache are accessed with a key.
* The key is composed of: <tile source name> + ":" + <tile ID>
  * see TMSCachedTileLoaderJob.getCacheKey()
* <tile source name> is the layer name with colons replaced by underscores.
  The layer name is localized.
* <tile ID> depends on the layer type:
  * TMS: <imagery URL> + "/" + <zoom> + "/" + <x> + "/" + <y>
  * WMS, WMTS: <tile URL> + <projection>
