volumetric needs no special case: it reaches a mesh only by inheritance and the
material has already mapped it to opaque (resolveMeshBlendingMode), so it
arrives here as opaque — and if it ever arrived raw, both predicates return
false, which is the conservative commutative-mode answer rather than a wrong
cutout.
Derive the pick-pass state from a blending mode.
