- WARNING: HORRIBLY SLOW CODE. PLEASE HELP TO MAKE IT USEFUL FOR LARGE AMOUNT OF PATHS
|

- add options:
|
||||
- replace trimmed paths by bezier paths (calculating lengths and required t parameter)
|
||||
- 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
|

- filter/remove overlapping/duplicates in
|

- in original selection
|

- in original selection (not working bezier but for straight line segments!) We can use another extension for it
|

- split bezier

- ...
|

- maybe option: convert abs path to rel path
