Just in case anybody is wondering, I solved the isue. What I do is:
- Save the .svg as an Encapsulated PostScript file (.eps) in Inkscape
- Insert the .eps as a picture into an OpenOffice text document
- Export the OpenOffice text document to a .pdf
When saving as .eps in Inkscape, I converted text to path, because otherwise it looked bad. But now I use MS fonts Arial and Times New Roman, and I think they remain nice in the .eps (but have not tried extensively).
When inserting the pictures into the OpenOffice text document, they look crappy, however, after exporting to .pdf, they are nice again, and they stay fully scalable.
