The notion that normals should scale along with the objects they are 
applied to is very intuitive. If there is a 1-unit bump on a 4-unit 
plane, and the plane is doubled, the bump should now be 2 units. That 
wasn't the bug. The bug was that POV sometimes scaled the normal and 
sometimes didn't.

The bug-fix included (after some wrangling with Nathan, as I recall :*) 
the feature of turning normal scaling off, which I am sure is a useful 
feature for some. But that scaling included normals was not a bug; the 
bug was inconsistency in scaling with normals. (For a longer discussion 
of this, see the original postings on this server.)
