It can't handle the following array properly:
A33_bug = numpy.array([[0., 1, 2], [3, 4, 5], [6, 7, 8]])
It should return
A33_bug_nearest = numpy.array([[0., 1, 2, 2], [3, 4, 5, 5], [6, 7, 8, 8], [6, 7, 8, 8]])
but return
A33_bug_nearest = numpy.array([[0., 1, 2, 2], [3, 4, 5, 5], [6, 7, 8, 8], [8, 8, 8, 8]])
