 SPECIAL THANKS:

    本ドライバの作成にあたり、大森紀人さんの gdevlips, gdevl4v.c を参考に
    させて頂きました。

 NOTES:

  - About Ghostscript 5.10/5.50 BUGS
    Ghostscript 5.10/5.50 の Vector driver の setlinewidth 関数には
    バグがあります。本来スケールが変更されるにしたがって線の太さも変更され
    なければなりませんが、Ghostscript 5.10/5.50 ではスケールを考慮するのを
    忘れています。
    このドライバはそのバグを回避するためにスケールを自分で処理しています。
