7 - 3d graphs, circular graphs
10 - make dash length available

35 - TODO: general documentation about attributes, clearing, merging?
36 - TODO: general documentation about changeable attributes?
38 - what about unit.cm() -> unit.cm, ...
39 - maybe we should never convert implicitly into visual/width, etc. lengths
40 - check that we always return the appropriate length, i.e., not
43 - might be moved into the graph
44 - perform calc by means of Python itself (see eval code in graph.data, but
45 we should use compiled code instead of eval)

73 - "undefined" corners of bounding boxes are no longer supported which makes
