#FIXME: segfault of the day: use this layer once without a route, and then with a route - and BOOM, need to investigate.
# TODO: should register a route manager listener here to update itself whenever the route/active WPT changes!
# also, if the layer is used in a dialog, the listener should be removed when the dialog is closed
if (me.route_monitor == nil) # FIXME: remove this listener durint reinit
me.route_monitor=setlistener("/autopilot/route-manager/active", func me.init() ); # this can probably be shared (singleton), because all canvases will be displaying same route ???
