// radius given), then for each object to test, calculate the distance to the 
// path and include it if the range fits and the target is in the line (0<k<1,
// as they call it).
// The implementation I took as reference is found at 
// http://astronomy.swin.edu.au/~pbourke/geometry/pointline/ 
// (they have a link to a C implementation, too)
// This approach is a lot like #2 commented on this function, which I have no
