53 * A component that manages some status information display about the map.
54 * It keeps a status line below the map up to date and displays some tooltip
55 * information if the user hold the mouse long enough at some point.

59 * The background thread does not alter any data of the map (read only thread).
60 * Also it is rather fail safe. In case of some error in the data, it just does
