    ENH: support arc edge specification with origin point · 1d08ed9b

    - The arc will frequently enclose an angle less than 180 degrees.
      For the case, it is possible to define the arc by its endpoints
      and its centre (origin) point. For example,
    
          arc 0 1 origin (0 0 0);
    
      When defined in the way, any discrepancy in the arc radius for the
      endpoints is resolved by adjusting the origin to ensure that the
      average radius is satisfied.
    
      It is also possible to specify a \em flatness factor as a multiplier
      of the radius. For example,
    
          arc 0 1 origin 1.1 (0 0 0);
