New description:
Some graphs which were missing in #9136. And I don't want to miss another
occasion to say that I hate topological graphs.
Theirs embeddings are the ugliest things on earth.
Nobody should study topological graphs. It has to be bad for karma.

Anyway... And we are almost done with the graphs from #9136 (short of
Tutte's fragment, which I doubt to be of any use independent from Tutte's
graph which this patch implements). Another patch on Snarks will follow,
today or tomorrow.
