Detailed Description

Result of a fused ReadAccessor::getDimAndActive traversal: the getDim(ijk, ray) step size and the policy-dependent active state of ijk.

The low 31 bits store dim and bit 31 stores active, saving one live return register versus {uint32_t, bool}. The default FloatTree's upper-node maximum is 4096. The constructor supports return {dim, active}; dim() and active() decode the packed value.
