The GPU compositor incorrectly extrapolates values of RGBA curves node. That's because the code introduces a half-pixel offset to the color values since they will be used to sample the curve maps. Those same values are then used for extrapolation, which shouldn't take the half-pixel value into account. This patch fixes that by computing sampler coordinate in a separate step.
