Text scaling in schematics is broken in the PDF

The scale and placement of port and circuit component labels is wrong in the PDF.

I have debugged down to this:

• The schematics in Python done with schemdraw are rendered to SVG using the svgmath backend (which is needed for Latex-style labels).
• When the Latex file for the PDF is prepared using pandoc, the SVG is rendered to PDF using rsvg-convert. Exactly this step fails, as the SVG (when looked at with Inkscape) looks OK, the rendered PDF is broken (as shown above).
• It is unclear, why rsvg-convert is causing this.
• Theoretically, Quarto can use Inkscape as a filter for SVG to PDF conversion, but I could not get this to work.

So for now I removed all Latex-style labels from the circuit figures. This is not ideal, but solved the issue for now. Let us keep this open until the tool chain is fixed.

Solved! :-) One has to add sd.svgconfig.svg2 = False to make it work. I will now rework all the schematics.
