Well, good work for me, too. I'll use it in my works (and am using now for a news) with a reference to you. Thanks.

Whereas, I did not understand your point. I did many maps in my life and it is a rule that if you color a country or city with, say, red, then all its territories should be red. It is nothing to do with the polygon discussions. Whatever the application behaves, the drawer must overcome the difficulty and obey the rules.
