dcraw code only normalizes the pre-multipliers for the number of colors in the raw image. LibRaw can set the pre-multipliers for a greater number of colors. For example, it can set the 4th multiplier for a 3-color raw. This causes the dcraw code to produce incorrect multipliers. Remove the 4th multiplier if the number of colors is less than 4 and the multiplier is equal to the 2nd multiplier. This lets the multiplier be set equal to the 2nd one after normalization. For images where the multipliers are not equal, print a warning.
