Simplify polygon to smoothen / reduce vertex count
Inkscape has this feature and this plan of an improvement demonstrates it quite well with pictures: https://gitlab.com/inkscape/ux/-/issues/201
I currently use it in Inkscape to smoothen a world map such that it can be used for lasercutting. Too many details are impossible to lasercut.
Other usecases are:
- reducing file size
- reducing complexity of paths for better editing
- reducing noise after vectorization of a raster-image
