I am trying to rotate an object around an axis, using, for example, this
code:

---------------
#declare myvector <1,0,1>;

object{myobject rotate 45*vnormalize(myvector)}
---------------

But the rotation is not around the vector specified. It works fine for
x,y, etc, but around other vectors it doesn't give the expected result.

I tried a loop with a range of rotations, to see the trajectory, and it
is not a circle, but some kind of cusp shape.

Is there something basic I am doing wrong?
