And here's a look at the b_spline and linear sphere_sweep, which also show
artifacts but something surprising to me about that.

The linear has only minor trouble; and the b_spline, while almost as bad as
cubic, will clean up entirely if tolerance 0.1 is used.

However, nothing rids the linear type of the smaller artifacts seen on the right
end of this sphere_sweep. I tried small tolerance and large tolerance and it's
appearance stays the same.

The camera location is a little to the left (or -x) of there along the z axis,
so isn't in direct alignment. look_at is a little more toward left too.

Sorry about image size, had to be this large to see all clearly.
