OSS CMM: Some quality problems with GRAY, PYCC and CIEXYZ color spaces with lcms library

Here is tolerance values that used for comparing results of the color transformations with ones obtained from original Kodak color management system:

Color Space Tolerance

sRGB 3
LINEAR_RGB 7
GRAY 11
PYCC 46
CIEXYZ 48
There are some quality problems with following color spaces: GRAY(not so noticeable), PYCC and CIEXYZ. Because of that following regression test is using large tolerance values for checking the result of transformations:
