Hi Ticker, do you have an example for such a problem case?

I think that the way a self-intersecting polygon is rewritten after a split using the Java2D library causes problems for the new algorithm when it makes a later cut for points limits or subdivisions, even when the next cut isn't in the overlapped area. All I've done so far is convert a few more places to use highPrec logic and then slightly disparaging at the complexity of the whole thing.
