 that the main diagonal scores maximally, since it's the 100% perfect
 self-match.
 
-To make the score matrix more intelligible, the pairwise scores are averaged
-over a sliding window which runs diagonally. The averaged score matrix forms a
-three-dimensional landscape, with the two sequences in two dimensions and the
-height of the peaks in the third. This landscape is projected onto two
-dimensions by aid of greyscales - the darker grey of a peak, the higher it is.
