Retail CPU-clips only portal polygons, punch fans and exit seals
(polyClipFinish); ordinary meshes, shells, terrain, particles and the
weather are never view-clipped. Inventory at edb32783: keep the seal and
punch clips (with equivalence pins), delete the per-slice weather loop,
the sky-post-scene particle clip slot, the dead cell-shell clip routing,
the slot-list shape of the part classifier, and the seven
ProbeCathedral* discriminators with their launch-option rows.
