Visio file that shows different arrow styles at different line weights

Visio scales arrow heads so that the arrow is consistent with the line weight. When importing a Visio diagram in Libre Office Draw, this is not reflected and all arrows have the same size independent of the line weight. See the attached files for examples.

The arrow heads are only initial implementation. Another entry-level task that could be done by someone trying to enter libvisio's world. The VSDXContentCollector::_lineProperties function is where all this is happening.

Checking with recent build of LibreOffice, it seems that your work, Bruno, fixed this one. Maybe we need to add more arrow styles, but as it stands, it is scaled.
