Operation logos

I like them a lot better!

I don't know if we are at that stage already, but eventually I think it would be good to have a "polishing" pass to make them fit into the same visual language (with consistent corner style, line width). A little bit more like the icons of this tool that @thadguidry shared earlier:

Also, for some of them (primarily star, flag) I think they could be aligned to the icons we currently use in the tool. Because those would need vectorizing I have opened an issue about that:

I have the feeling that this sort of task is one which requires a pretty specific set of skills which we don't really have in the team, so I am wondering how to reach out to other communities where people might like giving a hand. I know there are people on Commons active in vectorization of logos, perhaps that's one possible avenue.
