If everybody just cares about including PDF (for logos), I'm not sure if we need to implement support for SVG.PDF has much more features than SVG, so it's not obvious that that will be easier, and if we want to ingest the PDF graphic for output to SVG/PNG/PS, we'll have to interpret the PDF data, basically doing what Poppler does.
I don't understand how this is different from SVG.Poppler can render to a Cairo context just like Librsvg, see the example here:
https://www.cairographics.org/cookbook/renderpdf/ In terms of complexity for us, it's mostly equivalent. I've posted a request for feedback on lilypond-user to have a sense of which of SVG and PDF would be most useful. (It hasn't appeared on the archives yet, I'll post a link when it does.) A thought in passing: whether we take Librsvg or Poppler, we will need libjpeg. This should also enable us to support JPEG in addition to PNG with not too much effort.
