/**

But what is the brightness? The simplest answer might be that it is the average of the RGB components, but that neglects the way in which the human eye works. The eye is much more sensitive to green and red than it is to blue, and so we need to take less acount of the blue and more account of the green. The weighting used by GrayscaleFilter is: luma = 77R + 151G + 28B
