0c65385c82 Undoes older interpretation of alternating phase. 
I now understand, hopefully, that it's only the phase of the second colour component that alternates. That has the pointwise effect of reversing the colour signal. Hence the effect of phase errors cancelling themselves out up on successive lines up to a point.
