Thanks very much for the illuminating responses. I'd noticed the issue  
with the peculiar shape of the boundary lines, but these wiggles don't  
show up much on screen or when printed out, so I was less worried  
about them than about the hairline cracks.

As far as I can tell, I get this behaviour using the "ps", "psc", or  
"pdf" devices; and using any of the Cairo one, either "pdfcairo" or  
"pscairo".

If the issue is that the polygons don't have boundary strokes, might  
there be a simple way to modify the code so that such strokes are added?

Best wishes
