Thanks, but I don't think that's possible. They have to be processed sequentially because the next line segment to be processed could merge with a line segment that has been previously merged.
I was hoping for something more algorithmic because I will be coding this in C++ eventually anyway. I was perhaps thinking there could be something more efficient by not having to compute the square distance between each each pair of points. Perhaps that isn't possible.
