Yes, it seems that something very similar (identical?) to that construction is
required.

Thomas, try this example; it *looks* like it works-- the image_map or
image_pattern IS transformed, whereas the colors/pattern in the texture map are
NOT (or rather, they are inverse-transformed to bring them back to the original
look. I think!)  I made some simplifications to your code, so I could understand
what I was seeing. And the 'use-alpha' feature is something I haven't played
around with, until now.

Aside: In your code example, you have emission at 1.0. Are you actually seeing
any effects of the NORMAL that way? I thought such an emission value would
eliminate the normal's appearance (due to it being a 'lighting-based' effect.)
