MAJORLY redo the map service, so that it can generate even absolutely huge tiles (map layer size 8) in < 200ms, even with no cache. This will make loading the world map actually quick enough that it doesn't force the user to wait while the map loads.
Put the agent info serialization in the same place that backups are put.
Fix up SSA so that it can generate all the proper baked textures (excluding alpha wearables).
