Or perhaps that's even too harsh.  However, I'd much rather have this

"Slightly and only visible at extreme mag."

The part is good enough for now, and passes the critical checks:
orientation, origin, and filename.  And it looks pretty darn good.  At that
kind of magnification, you'll notice other errors in the corresponding
wheel- see how the axle hole isn't mapped quite perfectly to the surrounding
circle?

I hate to dig up this thread, but Tore had a very good point in a post about
a month ago that I think we could all take to heart.  I'll skip the thread
reference, but this part of the message is very useful:

  "The parts I make are good enough for making instructions
   and overqualified for animations, but never good enough
   for the authorizing crew."

  ...

  "There is a balance between quality and quantity and my
   opinion is that this whole thing has heeled over badly to
   paying attention to insignificant details."

This relates to what I think is something important to consider for the
future development of the LDraw library:  rating parts.  I see advantages
to adopting a rating scale like, say:

Not suitable -- not yet voted on, or with errors which make the part
unacceptable for the official library.
Acceptable -- meets the minimum standards for inclusion in the
library (and a more accurate version will not break models made
with this), but not as good as would be preferred.
Good -- the preferred level of quality for parts in the
library
Very Good -- almost perfect; models the part as accurately as
current technology allows

With such a scheme, it would no longer be a choice between accepting or
rejecting a part for all time; a part which was "good enough" could be
available to all users, while still being on the record in a visible way
as needing improvement so that parts authors who were so inclined could
find it and make those improvements.  Exacting standards could be applied
to parts to make the LDraw library as good as it can be (over time) while
not inhibiting the growth of the library.

Something to think about, anyway. . .
