Thank you for the tip on xrange.
Even if I swap the inner and outer loops, I would still be doing the same
number of computations, am I right (since I still need to go through the
same number of elements)? I'm not seeing how a loop swap would lead to fewer
computations, since I still need to calculate the outer rim of elements in
the array (defined by borderX and borderY).
