> Anyway, what I need is to do the other way back (generate a SVG file from some Geom::PathVector). The only code I found related to this functionality lies in the toys (not part of the lib) and uses a complicated scheme involving cairo and a lot of virtual func calls. Is there another way? If there is not, I want to implement it and I want to implement it fast. Would be possible to release another lib2geom version fast if code goes okay?

This functionality is already present in Inkscape, see
src/svg/path-string.cpp. However, it would be a good idea to move it
into 2Geom. Here is the optimal plan:

1. Make a method on SVGPathSink to output a PathVector into it. You
can copy the relevant code with some modification from Inkscape, see
src/svg/svg-path.cpp, or generalize the output_svg_path function.

2. Derive from SVGPathSink and implement SVGPathDataBuilder, a class
based on the code in src/svg/path-string.cpp.
