Adobe's SVG native is half way between librsvg and skia's svg rendering. Screenshots of 3 at https://github.com/HinTak/harfbuzz-python-demos/tree/master/skia-adventure
And diff against the skia-port code in the ../svg-native/ directory above, and
a lot more screenshots.
It shouldn't be hard to make a adobe+cairo version from the librsvg+cairo
version, if you see the adobe+skia version diff against pure skia (skia+skia
svg module).
