Oops, that "any" was too optimistic. The linearity correction in the DAC or Gamma LUT can work only if correction(P) + correction(1 - P) = 1. Otherwise, the correction has to be applied to L and R individually before the transformation, and must therefore be performed by some other (texture?) lookup in the 3D pipeline. - Viktor Pracht -- Der GMX SmartSurfer hilft bis zu 70% Ihrer Onlinekosten zu sparen!
