Mistake in rBab0bc65c24bd, in conversion of static 'common' sets of masks, BWEIGHT slipped in CD_MASK_MESH (probably from copy/paste from CD_MASK BAREMESH). Note that having it in CD_MASK_BAREMESH but not CD_MASK_MESH looks rather counter-intuitive, but this is not the time for that kind of cleanup. Went over whole conversion again, and found two other mistakes, should really have recheck that before committing...
