For this application, I disagree.  For a static image, yes, there is no
difference. But for an animation, hmm, how do you say in English...
There are two increments vs. three increments.  Take my caboose,
3 axises would be 1) it's laying on it's side (x), 2) it's standing on
it's end (z), 3) it is rotating around the y.
You can choose any one final vector using 2 axii, but to animate the
three rotations simultaneously requires all 3.
