    D.G.> activated by the \AltOverlayMode macro (undocumented, as far as I know...).

  Just after posting this message, I found that I was wrong on this point
(my apologizes for this wrong information), remembering a paragraph where
Timothy gave some explanations on this point and spoke of the reason to offer
two alternative methods (TUGboat, Volume 15, number 3, September 94, pages
239-246, http://www.tug.org/TUGboat/Articles/tb15-3/tb44tvz.ps ).

  "The only problem with translation is that the node connections and labels,
which use absolute coordinates, end up on the same overlay as the nodes that
are connected. Therefore, users can select an alternate method for making
material invisible: setting a small clipping path off the page. The problem
with this method is that it can only be undone with initclip, which can mess
up other macros that set the clipping path."
