Some of this has come up in various discussions. I'm not sure if all of it
has or not.

No, centering on a stud isn't necessary. Look at 3001.dat, the 2x4 brick. It
is centered on X-Z, not on a stud. The same applies for all other even-sized
dimension in a brick, plate, or tile. Generally, with LEGO parts, the X-Z
centerpoint will fall on a stud or half-way between studs. If a part is not
horizontally sized to a multiple of 20LDU, and the X-Z centerpoint is at an
odd location of the part, then maybe a different positioning should be
considered for that part.

At the very least, it should be in the LDraw FAQ. Jacob, can you add this?
If you want, I'll write up something slightly more formal.

I don't think there's any big secret. Nobody was looking very hard, checking
the orientation of the new parts to the old.

Right, I understood. I was just pointing out that such a program would have
to look at the versions of the parts installed (and the last change-date of
the model, probably) to know which parts needed fixing, and what fixing needed
to be done.
