I don't know if this is of any help, but Chimera uses the v2 alignment
except for 4-character atom names (typically hydrogens) which simply
get stuffed into the 4 available columns without the old v2 rotate-
last-character-into-first-column behavior. I believe this results in
v3 names in all cases.
