importers.py inconsistent format

[Timen]

Why does the code expect the bounding box in the hypotheses format as upper left:

   for i in range(nHypotheses):
            hypo = {
                'id':     s[5*i + 0],
                'x':      float(s[5*i + 1]),
                'y':      float(s[5*i + 2]),
                'width':  float(s[5*i + 3]) - float(s[5*i + 1]), # x - tl_x
                'height': float(s[5*i + 4]) - float(s[5*i + 2]), # y - tl_y
            }
            hypotheses.append(hypo)

And centre in the ground truth json:

for i in range(nAnnotations):
            id = s[13*i + 0]
            cx = float(s[13*i + 3])
            cy = float(s[13*i + 4])
            w  = float(s[13*i + 5])
            h  = float(s[13*i + 6])
