Hi Martin,

Thanks for posting this, this also helps as well. Although in one area it seems to be different than what Matt posted previously, I'll ask some more about that in a separate message in a bit here.

It is possible for me to control line caps in the PDF file, but trying to do this implies both discovering and maintaining some information about how different categories of lines touch one another. There's a good possibility that trying to figure that out and maintain that information throughout the whole process could add quite a bit of complexity to the whole thing so it's not too likely that I'll attempt that part.

I'll see about having an option for this.
