[mkgmap-dev] mkgmap splitter - Liechtenstein - horrible split if --polygon-file option used.

Hi Felix,

the polygon-file tells splitter that you don't want the rectangular bounds given in the *.osm file.
This means you don't want the areas outside of the polygon. If you are happy with the result without polygon file just don't use it

I think this applies to all "countries" / areas that are so small that they do not need a split or would split into very few areas. Another example is Monaco (2 tiles instead of 1 tile). For "countries" that are 10 tiles or more anyhow - I did not find this problem.

After last week looking at australia-oceania which was not splitted well without polygon-file - I now noticed that several small countries are split into way too many small tiles IF using .poly boundary file.

I guess there is some bug? This tile should not be split at all - as the node count fits into 1 tile!

Attached the splitter.log both with and without .poly file.
