The mixing function was designed to give correct results for Mix values of -1, 0, and +1, but the behavior between these points was not linear. This is unavoidable, because the function depends on both Mix and Mix^2 (by multiplying value and mf) so they could not cancel out completely. The new formula simply calculates the weighted sum without trying to invent a smooth function. Value for MixGlareOperation is now passed directly without scaling because it is then easier to use. Note that the previous formula performed max() twice for both input image and the result, now there is just one max() per channel because the glare input can't be negative.
