I assumed that a really simple object like my cylinder wouuld have a
well-defined, close-fitting bounding box. The strange thing is, I still don't
fully understand why the color_map spread on the object is so narrow (when not
using the fudge factors). I keep thinkling that my code has a conceptual error
somewhere-- but if so, I haven't yet found it. In theory, it should be doing
what I want it to do.

My own first thoughts were about a possible bounding-box error as well. But that
seems kind of strange, the reason being that the color_map 'spread boundaries'
actually increases across more of the object-- a wider color_map appearance--the
closer the object is to the camera position. I would think that the spread would
remain constant,  *if* the bounding-box error was constant as well. Which keeps
leading me back to wondering if there's a conceptual error...  ;-/
