Actually, as I look at those images again, I see that the extra space is not in
the 'Main camera'-to-object direction (well, maybe a tiny bit is) but rather in
directions +/- 90-degrees to that-- to the 'sides'. As far as my code goes (and
the chromadepth idea itself), the extra 'side' space doesn't matter; the
bounding-box volume and associated color_map spread are only important along the
camera-to-object line of sight.
