I was curious about the terminal command in the first link you posted. It turned it into an svg, but it didn't really make an svg. I was curious if it was going to be able to automate it a bit. I guess it gets all the colours in there though. You could probably do that outline tracing after that.
I'm curious about this too. Making SVGs is something I feel like I'd like but haven't touched.

This fucking Ambassador. Send him home and don't let him come back.
