Most of livarot is actually public domain. The license situation of
Inkscape is not completely clear, as currently it seems to contain
both GPLv2-only and GPLv3-only code, but most of the files are GPLv2.

Yes, the unfilled parts will be included. as counterdirectional
subpaths. 'Break apart' is equivalent to creating one Geom::PathVector
per Geom::Path. (Note that in SVG terminology, Geom::PathVector
corresponds to a path and Geom::Path to a subpath.)
