Urvang Joshi bd343f43ab Common Identity 16x8 transform: forward and reverse. 
The code for forward and reverse transform was exactly same, so moved to
a common header.

David Barker 838a53d623 Improve rectangular transform accuracy 
By adjusting the internal scaling and rounding in the transforms,
we can adjust the maximum round-trip errors to:
* 8x16 and 16x8: 0 pixel values (ie, transforms are exact)
* 16x32: 1 pixel value
* 32x16: 2 pixel values
