    Yunqing Wang authored
    This CL follows the original one"Sample selection in warped motion", and
    aims to reduce the number of samples gathered. We only search 1 above row
    and 1 left column instead of 1/2 bsize range in each direction. The gain
    is a little less, but not much.
    Borg test result:
                 avg_psnr ovr_psnr ssim
    cam_lowres:  -0.225   -0.228  -0.231
    lowres:      -0.081   -0.075  -0.114
    The changes are wrapped in WARPED_MOTION_SORT_SAMPLES macro.
