// I would've overhauled this entire system to be far more sane, but doing
// so would break every scene with RT lights that the artists have (as in
// they would crash and burn, or at best just not read in). As a result,
// as much as it annoys me to death, we can't do a damn thing about it.
// Hopefully, in the future we will be able to clean all of this out somehow
// (a conversion utility might come in handy, dunno).
//
// For reference, the setup SHOULD have separate paramBlocks for each rollout,
// using the P_USE_PARAMS to duplicate the shared ones, and all the rollouts
// should have *IDENTICAL* block and ref #s, so the shared code actually looks
// sane. The final block/ref #s needed would be kBlkMain, kBlkAnim, kBlkProj
// (for spots and proj dir) and kBlkAttenuation (projMaps don't need ref #s,
// since they're part of the paramBlocks).
