Hi developers, Probably many have already noticed, that the overview map (used to contain the polygons for selecting tiles in mapsource) isn't perfect. Often the polygons are much too large, or sometimes too small. They also feel like having a bias (at least for me). I have tried to fix this. And I think I was successful. After a short talk on irc we concluded: Instead of just commiting stuff, I will post patches here on the ML for review. So that people can give comments before I commit them. This is for mainly two reasons: 1) Some thoughts are not too simple, and I want to make sure, everyone understands them and at the same time, that they're right. 2) Some parts change some internals drastically and I feel, I might have overlooked something in this cause.
