KRW crossover components

edit
Identical topology…
ABZgl ABZg r
ABZ looks good
KRWgl KRWg r
KRW looks better
…different geometry
ABZgl KBHFeq
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. See WP:RDT/BSicon-KRW for single curve (non-junction) icons.
