* New: In Anabatic::AutoSegment::create(), allow the created segment to
be in any supported routing layer, and not only the bottom H & V.
Modifications impact the *two* overload of the function.
* Change: In Anabatic::NetBuilderHV::doRp_AutoContacts(), for punctual
METAL1, the protection has to be in METAL2. Bump the layer depth
to correctly use the updated verstion of AutoSegment::create().
* Change: In AnabaticEngine::checkPlacement(), for the Pin, check that
it's layer is in the routing gauge before anything else.
* New: In Katana::NegociateWindow::createTrackSegment(), if the track
nearest the segment axis (refTrack) do not exists, call a
breakpoint just before crashing.
