Martin Leitner updated FOP-2536:
--------------------------------
    Description: 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.
