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\+IA 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. \end{DoxyItemize} Implements \hyperlink{classKatabatic_1_1AutoContact_a690764ddc997fe9766a79c4b8e0c3e2f}{Auto\+Contact}.
