Well, I didn't really get that to work as well as I planned, since it may only
work with (x, y, z) functions and not my (px, py) functions.

I did manage to daisy-chain a massive pile of functions, follow the daisy-chain
of propagated parser errors, "fix" everything to the point where the code runs
without errors, and gives me --- something.
Not really at all what it's supposed to look like, but it's really square one of
translating a lot of complicated Shadertoy code with lots of magic numbers,
ridiculous equations, and very little in the way of explanatory documentation.

But I have hope that fixing it will be easier than that painful first step of
translating the raw code.  I'm sure I've failed to properly daisy-chain some
functions, so I'll go looking there first.
