    I can't quite figure out how to composite one image on another with a
    degree of transparency. All the "rubthrough" examples seem to show
    how to do it by creating a new image and then drawing on it using a 4
    channel color. I'm thinking that I want to read in two images and
    then draw to the alpha of one of them. Is this the right approach?
    If so, how do you draw on just the alpha? If not, how should I do it?

    Thanks,
    Thad
