; the input coefficients are scaled up by 2 bit (which we downscale immediately
; in the iwht), and is otherwise orthonormally increased by 1 bit per iwht_1d.
; therefore, a diff of 10-12+sign bit will fit in 12-14+sign bit after scaling,
; i.e. everything can be done in 15+1bpp words. Since the quant fractional bits
; add 2 bits, we need to scale before converting to word in 12bpp, since the
; input will be 16+sign bit which doesn't fit in 15+sign words, but in 10bpp
; we can scale after converting to words (which is half the instructions),
; since the input is only 14+sign bit, which fits in 15+sign words directly.
