Restore the topology (i.\-e. connexity) of the contact after one or both connected segments has changed layer.

Based on the layer depth delta between the two perpandiculars segments. Three case can occurs\-:
\begin{DoxyItemize}
\item The delta is {\bfseries zero}, then just sets the layer of the contact to the common metal layer (turn in same layer).
\item The delta is {\bfseries one}, then sets the contact layer to V\-I\-A connecting the two layers.
\item The delta {\bfseries cannot be equal to two}, due to the alternatives routing directions, it would mean a {\itshape turn} connecting two {\itshape horizontals} (or verticals) in different layers.
\item The delta is {\bfseries three}, then create a dogleg to restore the connexity. The dogleg will be created on the connected segment which as been {\itshape layer invalidated}. If both of them have been invalidated, the horizontal one is preferred.
\item A delta of more than {\bfseries three} is an error, and must never occurs.
