- https://github.com/abey79/vpype/issues/243
- command chain is slow on Windows
- add some debugging options to remove deprecation warnings
- allow to select other units than mm for tolerance, trimming, ...
- fix occult plugin sometimes not removing duplicate lines. maybe different stroke widths?
- allow to change pen width / opacity in vpype viewer: https://github.com/abey79/vpype/issues/243
- command chain is really slow on Windows (takes ~5 times longer than Linux)
- add some debugging options to remove deprecation warnings of vpype/vpype_viewer
- allow to select other units than mm for tolerance, trimming, ... At the moment vpype uses millimeters regardless of the document units/display units in namedview
