I'd like to print and export (to pdf) a document written in LibreOffice Writer which contains SVG figures. On the screen, LibreOffice displays and scales them correctly, but for PDF export (which should support vector graphics natively) and printing (to a postscript printer) the SVGs get rasterized (facepalm) at a very low resolution. I have tried to enable "reduce bitmap resolution" and set it to 600 dpi, hoping that telling LO a definite number for the resolution might help, but there's no change.
How do I tell LibreOffice to export and print scalable vector graphics as vector graphics or at least to rasterize them at a usable resolution?
Here's a screenshot of LibreOffice Writer (zoom level 400%):

This is a screenshot of the pdf exported by LibreOffice Writer (again 400% zoom level):

When printed from LO, the graphics looks just like in the pdf.
