I have not really done anything useful with routing so my thinking may be
all wrong. I was thinking that there is a green point A on top of segment P,
and another green point B on top of R and you want to go from A to B. If you
select the start point of P and end point of R and compute a route between
them, doesn't the route necessarily go also via A and B? Splitting the line
segments from the middle at exact locations of A and B would not make any
real change into the graph and routing because new nodes would be only
pass-through nodes with cardinality of 2.
