I straddled the fence for long time on this question before 
falling gracelessly on the side of making normals more like
the surface displacements they emulate. Even if this means 
adding a #version switch or potentially breaking every scene 
ever made for POV, (backward compatibility is a tyrrant!), but 
I just can't help liking the displacement emulating paradigm 
better than having to separately adjust bump_size. It's simply
more intuitive. I *could* learn to live with it either way,
as long as whatever paradigm is chosen is applied consistantly
to all kinds of normals, but automatically adjusting normals 
with scale statements is more sensible in the long term.
