Thanks, this gave me a springboard for further searching. It seems that
the term "order" not only has multiple meanings, it can also be
ambiguous within the same meaning! See conflicting definitions of
"order" just between these Wikipedia articles:
My takeaway is that I should purge the word "order" from my code and
documentation, and stick to "degree." Also, the release of quadratic
Bézier splines in SphereSweep will be delayed a day or two because of this.
