PSPP currently uses GIMP to generate PNGs from SVGs. GIMP is heavyweight, slow, and commonly not installed on developer systems, so we run it from Smake as pre-configuration.
There's a newer program called rsvg-convert that is much more commonly available these days. It is lightweight, fast, and more commonly installed (it is a binary that comes with the rsvg library, which is itself widely used). It produces good-quality output. I think that we could switch to it from GIMP, run it at build time instead of as part of Smake, and thereby improve the build process. Does anyone have comments on this?
