[Lcms-user] Bug in type TYPE_ABGR_8?

[Boris L. <b.l...@gm...>]

It is defined as:
(COLORSPACE_SH(PT_RGB)|EXTRA_SH(1)|CHANNELS_SH(3)|BYTES_SH(1)|DOSWAP_SH(
1))

On input it use:
Unroll4BytesSwap

      wIn[3] =3D RGB_8_TO_16(*accum); accum++;  // K
      wIn[2] =3D RGB_8_TO_16(*accum); accum++;  // C
      wIn[1] =3D RGB_8_TO_16(*accum); accum++;  // M
      wIn[0] =3D RGB_8_TO_16(*accum); accum++;  // Y

On output it use:
Pack3BytesAndSkip1Swap

       *output++ =3D RGB_16_TO_8(wOut[2]);
       *output++ =3D RGB_16_TO_8(wOut[1]);
       *output++ =3D RGB_16_TO_8(wOut[0]);
       output++;

which is different functionality!

one of them is wrong...
From my position it is on input side because on Windows you have BGRA
and not ABGR.
