Comment (by belg4mit):

 Hmm, the algorithm used is different than I imagined. However it seems
 like one possibility, although it would not necessarily scale easily
 beyond two cores, would be to have a pair of threads iterating over the
 raster cells: One beginning at the top left and the other working
 backwards from the bottom right.
