56 - support gsave and grestore in some way to make context handling easier?
61 - more details in path constructor: allowed pathels, first pathel...

68 explained at a central place.
69 - section titles: "Axes" -> "Axes - module axis" or similar
71 - linealign and circlealign

128 - introcuded an axis positioner (module graph.axis.positioner)
