3# optional plug-in to speed up worldmap rendering by dynamically 3# manages the worldmap by directing to other handlers
4# generating it out of an image
5# - saves loading time (less data to read)
6# - saves temporary space (only overlay stuff needs to be saved)
7# - might get reused as a generic tiled map
