> As already pointed out in a comment to the original issue, this is a problem with the
PDF viewers. FOP generates the borders correctly. The viewers render border segments correctly
when they are rectangles, but they make mistakes when the segments are more general polygons.
In my patch, I am splitting the polygons into rectangles, covering as much of the polygon
as possible, write the rectangles to the PDF, then write the remaining triangles.
