Librsvg appears to be designed to use Cairo to do any resizing for it.
IIRC librsvg does provide a way to change the DPI, but it’s
deprecated.
I’m curious if it would be possible to use Cairo in a toolkit
independent way to resize and render SVG files. The alternative, I
suppose, would be to find a different SVG library.
