Drawing selected edges: found the culprit!

Hi

after some deep digging with a number of incantations I found out that 
if a GRAPH-PANE has :EDGES-SELECTABLE-P set, then, eventually, a 
selected edge undergoes a CAPI::DRAW-INVERTED-PINBOARD-OBJECT (note the 
'::'!)

This is a straight function that cannot be specialized and there is no 
resort to CAPI:DRAW-PINBOARD-OBJECT-(UN)HIGHLIGHTED.  
CAPI::DRAW-INVERTED-PINBOARD-OBJECT calls CAPI:DRAW-PINBOARD-OBJECT.

So the question is: what is the definition of 
CAPI::DRAW-INVERTED-PINBOARD-OBJECT?
I need to change its behavior to draw selected edges in a more 
controlled (and aesthetically pleasing) way.


Cheers
Marco
