It's much different from what existed in 13.0. In that version all you can
do is move a label a small distance in pixels.
1) you can put any offset of any size in for a label.
2) you can offset in molecular coordinates (ax, ay, az) or in "screen" (sx,
sy, sz) coordinates.
I think the only thing it doesn't do is let you make labels, like echos,
adjust for window boundaries.
