This will also affect this line:
cfg |= cr | (cb << 13);
cr and cb are now swapped so this will result in a different color.
Sylwester, who is wrong here: the prototype or how this function is called?
I suspect that Gustavo is right and that the prototype is wrong. But in that
case this patch should also change the cfg assignment.
