The MAIN ClippingPlane a SliceState describes, or null before
placement. flipped negates the normal (swaps the kept side). The plane is
returned regardless of active — callers gate application on active
themselves. For the bounded slice VOLUME actually applied to the scene, see
planesFromSliceState.
