SvgRender is the place to resolve Scratch 2.0-specific SVG rendering quirks, and fixes there will fix both scratch-render and scratch-paint. Fixes here https://github.com/LLK/paper.js/blob/f255218f36299dff5a7fe74af1ef6159c55b0ea4/src/svg/SvgImport.js#L304 risk different behavior between scratch paint and render. Is this the right place for them to be? (Some of these fixes deal with SVGs in general and not just Scratch 2.0 SVGs though)
