146 ; therefore, a diff of 10-12+sign bit will fit in 12-14+sign bit after scaling,
149 ; input will be 16+sign bit which doesn't fit in 15+sign words, but in 10bpp
151 ; since the input is only 14+sign bit, which fits in 15+sign words directly.
243 ; 4x4 coefficients are 5+depth+sign bits, so for 10bpp, everything still fits
414 ; 17+sign bpp. Since the multiply is with 11585, which is 14bpp, the
415 ; result of each multiply is 31+sign bit, i.e. it _exactly_ fits in a
416 ; dword. After the final shift (4), the result is 13+sign bits, so we
651 ; coef values are 16+sign bit, and the coef is 14bit, so 30+sign easily
789 ; dc-only - unfortunately, this one can overflow, since coefs are 18+sign
790 ; bpp, and 18+14+sign does not fit in 32bit, so we do 2-stage multiplies
1106 ; coef values are 17+sign bit, and the coef is 14bit, so 31+sign easily
