no visible effect for the first point, agree, but I thought the rotation would
(should!) still exist and propagate when subsequent points are calculated.

the next question, then, is how to specify a point <5,0,0> and corresponding
vrotate()s to give me two separate X-axis rotations (as I tried with the two
rotation vectors)?  do I have to pre-compute some point not-on-axis beforehand,
or is there a "clean" way?
