I guess I was assuming that if you were milling a PCB you were prototyping
and thus hand assembling.  Of course you could still mill individual
outlines if you wanted -- I was just looking at options to speed it up.
It's an interesting geometry problem!

polygon1.c is "PCB code" that knows how to render PCB objects (like pads
and lines) as polygons.  polygon.c is a polygon library of sorts.  Someone
pasted in a long explanation I wrote into one of those (polygon1, I think).

It knows how to make arcs, but it makes them out of straight segments.

I can only handle one Dave at a time!
