<param name="desc" type="description">This tool helps you to find nasty contours which might bug you and prevent your work from being ready for production. It will find open contours, closed contours and self-intersecting contours. Intersecting contours can be closed or open contours so you can select this option additionally! Last ones usually happen if two or more handles (points) are coincident but which you might don't see. Or you just have large overlaps where the contour crosses itself like an 'eight' character for example. Using the highlighting it's easy to find contours with unproper path handles. Note that if you did not select any paths it will scan the whole document instead.</param>

"""
Extension for InkScape 1.0
Features
- helps to find contours which are closed or not. Good for repairing contours, closing contours,...
- works for paths which are packed into groups or groups of groups. #
- can break contours apart like in "Path -> Break Apart"
- implements Bentley-Ottmann algorithm from https://github.com/ideasman42/isect_segments-bentley_ottmann to scan for self-intersecting paths. This only works correctly if your path is within the canvas correctly. Otherwise you might get "assert(event.in_sweep == False) AssertionError". This is commented out yet
- colorized paths respective to their type
- can add dots to intersection points you'd like to fix
