[PATCH] How to use native text with EPSDocumentGraphics2D

As reported recently in the users mailing list the code:

OutputStream out = new FileOutputStream("mini-test.eps");
EPSDocumentGraphics2D g2d = new EPSDocumentGraphics2D(false);
g2d.setGraphicContext(new GraphicContext());
g2d.setCustomTextHandler(new NativeTextHandler(g2d, null));
g2d.setupDocument(out, 200, 100);
g2d.setFont(new Font("Helvetica", Font.PLAIN, 12));
g2d.drawString("Hi there", 50, 50);
g2d.finish();
out.close();

generates invalid EPS files.
