Thanks for the observation Jeroen.

I've not much experience with SVG myself, so I do not have an opinion right 
now. If we settle for a cross-platform, easy to deploy solution, I do not think 
it will be difficult to integrate. I was just remarking that MuPDF comes with 
its own SVG interpreter, which could be ok for most use cases. Since SVG is a 
very complex format (like HTML/CSS), I guess at some point one should rely on 
an external tool like Inkscape to produce a reasonable rendering and then use 
that in the document. Depending on the use case, actually, once we have a PDF 
renderer it would be ok to convert the SVG to PDF with an high quality tool and 
then use the PDF version in the document. So I guess, supporting at least one 
vector format would be enough for creating good quality PDF documents. 

Best, 
Max
