x = 2 * (x / (W - 1) - 0.5)

Hi. I am confused about your backwarp implementation. To my understanding, for a 2x2 image, the coordinates for the four pixels are (-0.5,-0.5), (-0.5, 0.5), (0.5, -0.5), (0.5, 0.5), respectively. But in your implementation, the coordinate of upper-left pixel is (0,0)? Did I misunderstand anything?
