Glad to hear :)

The idea of pipeline is also inspired by AGG, and I did do something
similar with AGG as you did. The difficulty with AGG is that it uses
external iterator pattern, which makes it hard/tedious to write a graphic
or an adaptor, because the path has to keep some state for traversal. In my
lib, I promote the use of visitor, so defining a graphic or an adaptor is
straight forward.
