Docs

[DerThorsten]

• added subsection for "styled" drawing in the "Drawing Shapes" section of the sphinx documentation
• minor fix in example notebook (wrong color was used)
• change of docstrings

[DerThorsten]

added the styled methods at the places you mentioned. Would been nicer to avoid the manual (re)-writing of the methods signature / docs by just cross-referencing the API documentation itself, but could not make reference work with smth like

:meth:`mymodule.MyClass.mymethod`
