You watch Matt Parker to regain your sanity? I have some of his videos
languishing in my "Watch later" list because I'm afraid I'll *lose* my
sanity if I watch them.

I am not convinced that this property is directly relevant to the
problem I am trying to solve. I still think the key is in that quartic
equation I came up with, which should not require numerical methods
(beyond what's implicit in POV-Ray's built-in functions). The problem
is that I am not practiced in solving quartic equations.
P.S. I have known since 2007 that there is no exact formula for an
ellipse's circumference. I discovered that while trying to weld this
'O' to the rectangular plate using an ellipse made out of blobs.
