The Lighten blend mode is wrong for factors less than 1, as it is computed as a weighted maximum using the factor as the weight, while it should be a simple component-wise maximum. This is correctly implemented for Compositor, EEVEE, and Cycles. But the render/material implementation is wrong. So we adjust the implementation to match the correct one. The Darken counterpart was already fixed in1dcf956849. While the lighten was fixed in8b7b165ad9among other patches. This just completes the fix.
