I doubt it, unless somebody else has worked up a more capable function 
language. I'm talking about something more like (roughly):

define BasicCamera = camera {...usual camera stuff...}

special_camera {
    function trace_pixel(x, y) {
        define pixelColor = BasicCamera.trace_pixel(x, y);
        return pixelColor + (1 - 
pixelColor.alpha)*bkgndPigment(x/image_width, y/image_height);
    }
}

Again, highly doubtful. What I'm talking about would require something 
like my G project (now called Amber), which hasn't made it into a really 
useable state yet.
