Real-time interactive milling simulation using exact mesh booleans (~1 ms per step).

I teased this on the weekend. This is super hard for various reasons.

The sphere is actually sweeped each step, so we have a unique ~300 tris mesh each time. No preprocessing possible.

Then the sweep starts at the exact location the previous ended, meaning ~100 coplanar tris each time.

The workpiece accumulates triangles away from the "action" which must not affect perf.
