<snip growing array code> That concept is used already for MAX_SUBAREAS, which started out at 100 but it soon become clear that it was insufficient, I think there are tiles >10000 subareas for example. So I added the dynamic thing for that, and fixed some O(N^2) loops at the same time. MAX_SEGS > 100 means that it found that the coastlines cross the edge of the box 200 times. While not impossible it's certainly quite a bit higher that I thought would happen in real life. Then again, as the number of divisions gets smaller the edges get longer and so perhaps its possible. It could be increased but I wonder how the performance will be affected. What is missing is an abort when it happens. Not expanding the array and not checking for overflow is the worst of all possible ways.
