      charts.
    - New module `Diagrams.TwoD.Path.Metafont`, for specifying

    - New module `Diagrams.TwoD.Path.Calligraphic` for making simple
      "calligraphic" strokes.
    - New module `Diagrams.Lens` with lenses for working with
      diagrams.

* **Bug fixes**

      avoid iterated transformations, giving a significant performance
      boost.

0.7: 9 August 2013

      blending colors in HSV space.

      `Diagrams.TwoD.Layout.Tree`.

0.6.1 (23 March 2013)
---------------------

* **New features**

    - New `Diagrams.TwoD.Path.IteratedSubset` module, for constructing
      paths using an "iterated subset" algorithm (repeatedly replacing
      segments with a given path).

    - New `Diagrams.TwoD.Layout.CirclePacking` module for
      circle-packing layout

    - New `Diagrams.TwoD.Factorization` module, for creating
      "factorization diagrams" as seen at
      http://mathlesstraveled.com/2012/11/05/more-factorization-diagrams/
      and on the cover of Hacker Monthly
      (http://mathlesstraveled.com/2012/10/05/factorization-diagrams/).

    - `Diagrams.TwoD.Path.Turtle`: generalize `runTurtle` function,
      and add new functions `drawTurtle` and `sketchTurtle`.
      `drawTurtle` results in a diagram (like the old `runTurtle`),
      and `sketchTurtle` yields a path (ignoring pen style commands).

	- New `renderTree'` function which gives
	  the edge-drawing function access to the values stored at the
	  nodes instead of just the node positions.

	- The type of `renderTree` is generalized to work with any
	  `QDiagram b R2 m`.

* **Bug fixes**

    - Tiling generation code in `Diagrams.TwoD.Tilings` wasn't actually
      checking whether vertexes had been already visited.

* **Dependency/version changes**

    - Switch from `fclabels` to `lens`

0.1.1.1: 13 May 2012

    Yorgey)

    "turtle" interface (Michael Sloan)
