TODO:
  - graph module
    - do not include unneeded line segments when the axis range is set manually
    - allow for an iteration of a graph style, when it is used several times

    - common bboxes for different graphs
    - automatic datafile key title
    - exceptions in drawsymbol & friends...

    - rect style (and errorbars?) should use clipping
    - should the divisor argument be moved to the texters?
    - is the divisor argument really necessary?

      should be removed
    - Docu: part -> parter, tickdist->tickpos argument of parter
  - style module:
    - default patterns
    - make dash length available

     - callers use inplace add where possible now (yielding a considerable
       speedup)

    - internal methods return coordinates in pts
    - lentopar returns tuple not list
    - added path.arclength_pt, path.at_pt, path.begin_pt, path.end_pt (and
