- replace trimmed paths by bezier paths (calculating lengths and required t parameter) - replace trimmed paths by bezier paths (calculating lengths and required t parameter)
- detection of collinear segments: special case where it seems not to work 90° angle between two lines - detection of collinear segments: does not work sometimes because it generates pointy paths or kicks out paths which still should be inside the data set
