       * and goes right, there is a one pixel shift in the pattern.

       * then the left and bottom in another call, fixing up
       * the dash offset for the second call ourselves to get
       * continuity at the upper left.

       * the upper left and lower right instead of two intersecting
       * lines but that's only really apparent for no-dashes,
