Tilman,

Yes, this is the same project from last year.  I suspended it in the interim 
for other priorities.

It's still a goal for us, SVG is a much better, scalable representation of many 
PDF documents.  We are getting really close to having it be a good solution.

I'm going to experiment with doing the pattern across the range block of the 
shape.  Hopefully that will handle this issue.
