Comments
EVALUATION This bug is only reproducible on windows platform where we are using GDI for filling shapes. Unfortunately, GDI operates with integer coordinates and also not so accurate as our software loops so we end up with such kind of problems. The problem can be solved (at least for some extent) by more sophisticated rounding of the control points than we currently have.
