Notes:
The lower right box is the "ghost." A copy of the image can be drawn in
this box, but it is not iterated into the other boxes.
The number of pixels should be at least 2^(#levels+1). Computation of
further levels does not improve the image quality.
The "head" color is the color of the largest filled-in box; the "tail"
color is the color of the smallest filled-in boxes; and the "fractal"
color is the background color, which becoms the color of the un-filled
fractal portion of the image.
The brightness attributes can be used to generate a decent background for
light or dark web pages.
