The mis-match seam comes from my attempt to give my own image_map the same
'tilt' of the pattern as Lanahum's...although I didn't get it quite right. Then
the pattern repeats on the sphere, causing the visible 'seam'.

That small circle on my sphere renders is also visible in Lanahum's original
post, although not as pronounced. I don't quite know what the cause is, as I
have not really examined his code in detail, and just used it as-is. (Although,
I did comment-out his various matrices to simplify the code, since they were
having no effect as far as I could tell.) The circle might be because the
bump_map's image_map does not exactly fit the sphere(?) or is not exactly
aligned to it. (We are both using map_type 0 for applying the bump_map, which is
just planar mapping, not 'spherical')
