Review for: tdf#143432 and more, improve wrap contour export

[Regina Henschel <rb.henschel@xxxxxxxxxxx>]

Hi all,

this is about patch: "tdf#143432 and more, improve wrap contour export"
https://gerrit.libreoffice.org/c/core/+/120169

The patch is ready for now. I would be happy about a review. In case, 
please let me know, that you want to have a look at the patch.

The patch still contains some ToDo, but they can be solved later.
In particular, wrap polygons for the shapes of the legacy oval and 
legacy rectangle toolbars are missing.

Kind regards
Regina
