Have you tried a 3x3 box centered on the endpoint?  Anything to avoid
a linear search...

I think expanding the rtree to include the boundaries would be
acceptable for the GUI, but the autorouter uses it also, and it has
very specific requirements about which boundaries are included in
which rectangles.
