Ah, good question. I am trying to filter out objects the are very small
from rendering. At some zoom levels these objects are just to small to
be meaningful to render and end up looking like dirt on the image.

Hmmm, I guess I need to rethink. I suppose I could add a length 
attribute and filter on that, but I was hoping I could do it based on 
the rendered size. Can you think of a better way to do this?

Thanks, I can update the mapfile for the patterns.
