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

The recursive transform block partitioning system naturally supports
the use of rectangular transform block size. Hence there is no need
to make a separate coding route for the rectangular transform block
size support there.
