A beam can be shifted from the symmetry axis of the elements by:
6 S(HIFT) B(EAM)
<x-displacement in meter>
<a-angle displacement in rad>
<y-displacement in meter>
<b-angle displacement in rad> ;
[example: S B 0.02 0.001 ;]
This command can be used to describe a displaced beam at the entrance of
the system, it can also be used to describe a displaced optical element
by displacing the beam before and after this element. WARNING: this looks
a little bit silly in a graphical output.
