| * <p> |

| * class-variables <code>currentIPPosition</code> and |
| * <code>currentBPPosition</code> hold the position of the currently rendered |
| * area. |
| * <p> |
| * <code>Java2DGraphicsState state</code> holds the <code>Graphics2D</code>, |
| * which is used along the whole rendering. <code>state</code> also acts as a |
| * stack (<code>state.push()</code> and <code>state.pop()</code>). |
| * <p> |
| * The rendering process is basically always the same: |
| * <p> |
| * <code>void renderXXXXX(Area area) { |
| * //calculate the currentPosition |
| * state.updateFont(name, size, null); |
| * state.updateColor(ct, false, null); |
| * state.getGraph.draw(new Shape(args)); |
