Detailed Description

The Color transformation matrix object allows complete color space transformation (shift, rotate, skew, add).
The matrix coefs are in rgba order, hence the color RGBA is transformed to:
        R'              m0      m1      m2      m3      m4                      R
        G'              m5      m6      m7      m8      m9                      G
        B'      =       m10     m11     m12     m13     m14             x       B
        A'              m15     m16     m17     m18     m19                     A
        0               0       0       0       0       1                       0
Coeficients are in intensity scale, ranging from 0 to FIX_ONE.
