Ah, I forgot about that.. my ISPs web ftp server has been corrupting
most of what I upload lately.  I'll try to find another way to post
them.  Locally, my dia files are fine, and only the three PNG files
have that strange artifact.

Bitmap?  Why not vector?  I was assuming that since the dia-grams are
vector, and PNG is vector capable, that bitmapping would be
unnecessary.

They are fine.  Though my diagrams have hard edges and don't need
softening, they look fine.  As soon as I export them to png and view
them with gqview and other viewers, the vpn concetrator is screwed up
on three of the diagrams.
