 displayOn: aGCOrStream

Compatibility
append a printed desription on some stream (Dolphin, Squeak)
OR:
display the receiver in a graphicsContext at 0@0 (ST80).
This method allows for any object to be displayed in some view
(although the fallBack is to display its printString ...)

 isSelf

return true, if this is a self-node

 acceptVisitor: aVisitor

Double dispatch back to the visitor, passing my type encoded in
the selector (visitor pattern)
