I used what is in 1.3 (though I actually used Peter Grogono’s PDF MetaPost: A Reference Manual <https://users.encs.concordia.ca/~grogono/Writings/mpref.pdf> which I find the best educational document about plain METAPOST so far).

1.18 was what I was looking for but did not work in my situation (don’t know why, but it exploded). I fixed another issue (calling cornering on top of cornering when doing recursion) and that made my own macro behave perfectly civilised.

I had looked at 2.5 and 2.6 but this was not required (nor of any use).

I wrote my own, but it is giving me headaches so I’d like to find something that is better than what I produce.
