Comment (by ncohen):
> * modifying the code in #19520 to manage the embedding seems difficult
(by the lack of a proper class for planar graphs, as I have said before).
I would love to, and maybe will need too, but this will be hard.
You can easily manage embeddings right now, with get/set_embedding. All
you need to know is the order of the neighbours of every vertex 'v'. Don't
we have this information when building the graph?
> * the 'is_planar' is much too slow, and is in fact re-building by brute
force the embedding we should already know.
Okay.
> * one option would be to drop the code in #19520 and get the edge graph
from the code here. I would prefer no too. This is just a little code
duplication, do you really mind ?
I don't mind if there is no way around it, and if there is an easy way out
I prefer it.
> * I still have other projects in the same vein..
Do you plan a third copy/paste because of some information that you cannot
find from the function you implement here? `:-P`
