[mkgmap-dev] splitter r269

Hi Gerd,
while playing a little bit with splitter-r269 and bounding-polygons I 
found something strange with my scandinavia-polygon. If you compare 
scandinavia.poly and scandinavia.kml, the tiles are around iceland a 
little bit larger than bounding-polygon. If you open both files in josm 
and also bing sat-image, you'll see, that in the overlapping parts 
typical shouldn't be any data.
Is it a bug in your algorithm or is it in the limit? If second, it wont 
be a problem at all.
