Yes, I just noticed that as well.  That's how the tikz pgf code looks (a
sequence of line_to and curve_to commands and so on) so it should be easy
to port over the various shapes.

Sure, but I may as well port them all of the tikz arrowheads over since
most of the work would be figuring out how to do it.
