But the stud subfile was mirrored. At the lowest level, the ldraw
system doesn't differentiate parts, models, primitives, etc. It just
knows about files. So mirroring a stud primitive is logically identical
to mirroring an entire part.
BTW, I've submitted a fixed version of 4869 to the PT. It correctly
rotates the stud, instead of mirroring it.
