In the previous loop iteration, w11 was the center point, and our
vectors contain the following data from the previous iteration:
vecYUV5555 = { w11, w11, w11, w11 }
vecYUV1234 = { w00, w01, w02, w10 }
vecYUV6789 = { w12, w20, w21, w22 }
Now we have the new center point w12, and we would like to have
the following values in our vectors:
vecYUV5555 = { w12, w12, w12, w12 }
vecYUV1234 = { w01, w02, w03, w11 }
vecYUV6789 = { w13, w21, w22, w23 }
To this end we load a single new vector:
vTmp = { w11, w03, w13, w23 }
We then can compute all the new vector values using permutations only:
vecYUV5555 = { vecYUV6789[0], vecYUV6789[0], vecYUV6789[0], vecYUV6789[0] }
vecYUV1234 = { vecYUV1234[1], vecYUV1234[2], vTmp[1], vTmp[0] }
vecYUV6789 = { vTmp[2], vecYUV6789[2], vecYUV6789[3], vTmp[3] }
Beautiful, isn't it? :-)
