Detailed Description

*** fix me!Interface for EllipseData objects.

  old:
   TO DO:

   draw only whats necessary
   ellipses start==end==0 means whole
   start/end angles
   move focus don't work circle kind of flaky/ out of phase with rect

   from inkscape/sodipodi:
    move start/end inside makes chord, outside makes pie

Todo:

*** totally broken, needs some serious rewrite..

*** must be able to fill also?
