Actually, its vectorization is straightforward (to process a matrix of 
points without explicit "for" loop,
instead of a unique point). But the script has other problems.
Special cases (horizontal segments, points on segments, etc) are not 
really handled.
Nevertheless, you may give it a try as is. Or improve it for special cases.
