Crossover components edit

Identical topology…
uABZgl uABZg+r
ABZ looks good
uKRWgl uKRWg+r
KRW looks better
…different geometry
uABZgl uKBHFeq
ABZ good, smooth
KRWgl KBHFeq
KRW bad!, crooked

KRW (from the Dutch kruiswissel; literally cross exchange) icons are for crossing between parallel lines, and should not be confused with ABZ icons used for branching off from a line.
