%description
The function takes a DNA sequence, a start point, an end point in the
sequence, dot size and dot color and draws a fractal image of the
sequence. The fractal starts in the center of the canvas. The image is
drawn by moving base by base along the sequence and dropping a midpoint
between the actual point and the corner designated by the actual base. For
more details see Jeffrey (1990) <doi:10.1093/nar/18.8.2163>, Hill,
Schisler, and Singh (1992) <doi:10.1007/BF00178602>, and Löchel and Heider
