181 If a motion acceleration structure is traced with code:OpTraceRayKHR, it
182 behaves as a code:OpTraceRayMotionNV with code:time of 0.0.

254 If code:SkipTrianglesKHR was included in the `Ray Flags` operand of the ray

377 geometries need to be either confirmed or discarded by shader code.
400 This can again be overridden by including code:OpaqueKHR or code:NoOpaqueKHR
