Flatten (almost) everything in an SVG document to <path> elements without transforms. See the demo at pathologist.surge.sh. You want to create artwork in Illustrator or Inkscape, but you need a flat list of paths so that you can, I don't know, easily render it to <canvas>. To be honest it's probably a bit niche. But I needed it, and I've been surprised in the past to learn that other people share my esoteric requirements, so here it is. Make of it what you will.
