When the interpolated value is divided by the sum of weights, no rounding is done, which means the value is truncated. This results in a slight bias towards dark green in the interpolated area. Rounding properly removes the bias. I measured this change to reduce the interpolation error by 1 to 2 % on average on a number of sample input and logo area combinations.
