Edges longer than ca. 10m are considered 'crazy' in the TD Workbench. Hatch patterns are also checked. As a workaround some intermediate scaling is applied.
Addionally: `transformShape` instead of `transformGeometry`. The latter results in B-splines.
Since Py3.11 the methods names __setstate__ and __getstate__ conflict with the method names added to the object class.
Thus rename them to 'loads' and 'dumps'
