    Gnumeric has a superset of the line styles and background patterns
    supported by MS Office and Applix. This includes the enumeration,
    draw, and print support where possible.

    A few things to note.
    - Once you support non-uniform borders you'll want to give careful
      consideration to dominance in the corners, There is lots of icky
      +/- width type logic to have everything 'do the right thing'
      This goes double for supporting 'double line' style borders.
      Getting the corners right is a pita.

    - Be wary when you go to print the borders of the semantic
      differences in drawing coordinates and printing coordinates.
      Printing has the notion of a line _centered_ at the coord.
      Drawing coords are pixelized. This is rather noticable when
      printing borders. It can be fixed, but it takes care.

    Gnumeric has a display neutral engine for tweaking the coordinates
    but I'd still like to expand its logic a might. to be smarter about
    implied dominance due to similarities (eg dominance based on more
    than position)
