  - Uses Bentley-Ottmann algorithm to detect intersections
  - Allows to separate different contour types by colors
  - Works with paths which have Live Path Effects (LPE)
- - Does not find overlapping colinear lines (sweep line algorithm does not intersect them)
+ - Finds overlapping / collinear lines
