You asked how to rotate a vector <0, r, 0> so that it ends up
pointing at the same direction as a vector A. That's precisely what
the Point_At_Trans() macro does.
(Or, more precisely, the Point_At_Trans() macro creates a transformation
which you can use in an object or to modify a vector using vtransform).
