/* Vector Version of LIPS driver */

/*

   Vector driver は Ghostscript 5.0 から新たに加わったドライバです。
   よって仕様が安定していません。Ghostscript 5.10 と Ghostscript 5.50 では
   Hi-level bitmap imaging の仕様が変わっています。
   Ghostscript 6.0 では更に text_begin という API が追加されるようです。


   ○Ghostscript 5.10/5.50 のバグについて

   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。(バグ報告を2回ほど送ったのだけれど...)
   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。

   Ghostscript 5.10 の生成するパスは Ghostscript 5.50 が生成するパスよりも
   非常に効率の悪いものになることがあります。LIPS IV の処理できる限界を超える
   こともありました。効率の悪いパスは速度の低下にもつながるので Ghostscript
   5.50 を使った方がこのドライバでは出力速度が速くなります。

   また Ghostscript 5.10 では
   fill_trapezoid、fill_parallelogram、fill_triangle
   の関数の挙動が変になることがあったのでこれらは使っていません。


   ○ LIPS IV のバグについて

   このドライバは開発中に発見した次の LIPS IV のバグを回避しています。
   1. 1 dot のイメージを変形したときに座標の計算が狂う
   2. 小さなイメージを描画すると正常に描かれない
   3. クリッピング命令とパス・クリッピング命令がそれぞれ独立に働いてしまう。

   1. は 1 dot のイメージを矩形にして回避しました。
   2. はイメージ領域確保命令で分割を指定することにより回避しました。
   3. はクリッピング命令を使わないことにして回避しました。


   ○ LIPS IV の仕様について

   1. 単色イメージ・カラー指定命令はグレースケールイメージに対しても
   働いてしまいます。
   2. LIPS IV ではグレースケールの色表現が PostScript と逆です。
   3. LIPS IV にはイメージのビットを反転させるコマンドはありません。
   4. LIPS IV には CMYK のカラースペースはありません。
