Comment (by vmb):
Whoops, sorry, for "16-bit" please read "19-bit". It started as 16 bits
and then Mark added three more because some of us complained.
As for the calculation, it's not what C would do (unless you started by
casting the RGB values to shorts and shifting them left by four before
shifting right again, I guess) -- I believe that the adder is wide enough
that there is no truncation of the less-significant bits till after the
sum is taken.
