So it doesn't happen with EHY anymore? It's kind of weird because this
should have been fixed with the patch I made to invoke the normal
generation function only once per hit point.
This is the offending line from ehy_shot.cl:ehy_norm() which caused the
issue:
hitp->hit_vpriv.x = scale;
Because it modifies vpriv if you do a second normal computation you get
bogus results.
