Not using fltk. You may be able to do this using other libs though, but...

Note that it is possibly overstating things to say that fltk "supports" Cairo, as there is no fltk back-end that actually renders via Cairo.
It is perhaps better to say that fltk can work with Cairo, I suppose.

Fltk really only deals in pixelmaps internally, so where we use SVG, we tend to rasterize the result for display, as you note.

There are other libs that can handle SVG files and work with Cairo, so you might be able to use one of those to get the SVG loaded into Cairo in a suitable (presumably vector) form.

However, the only lib I actually have any idea about that reads in SVG files and can render them with Cairo is librsvg which, AFAIK, also rasterizes the SVG file for display, so presumably does not retain the vector form.
I may be wrong about that!
And in any case there's a fair chance it (librsvg) does a more thorough job than our rasterizer, which we picked because it was fast and light, not because it was the very best SVG rasterizer...

But don’t take my word for it, as I don’t really know SVG and Cairo, beyond the bits I have done to solve the specific issues I had!
