remove the pathological multiplier for being useless

[1e1001]

the pathological multiplier is defined as

max(w, h) / min(w, h) × w × h

substituting for all possible orderings of w and h:

• w < h: h / w × w × h = h × h
• w > h: w / h × w × h = w × w
• w = h: n / n × n × n = n × n (where n = w = h)

thus this is equvialent to max(w, h)²

because the comparator is only used for sorting the rectangles, and negative-sized rectangles are generally not used, max(w, h) and max(w, h)² will sort the rectangles in the same order

since max(x, y) is already one of the comparators, this means that the pathological ordering is redundant
