[mkgmap-dev] splitter r247

Could splitter output a sensible polygon on runs without using one 
afterwards? Geofabrik doesn't change their polygons often, so if one 
runs it, splitter creates them, and one can reuse them for future runs, 
that would be the best I think...
Maybe splitter could add 100m or 200m on generation, so small changes 
wouldn't matter (or does the polygon need to be exact?).
