It could work like MScaleVect, but bit-depth difference (instead of blocksize) should affect SAD readjustment.
On the other hand, I planned to revise 10-16 bit SAD functions, now they are simd intrinsics, which can be changed into faster hand written asm. And it can be even faster for 10 or 12 bits, taking into consideration of possible sum overflows.
