JavaX fragment (include)

please include function renderText.

static BufferedImage renderText_multiLine(S fontName, float fontSize, S text) {
  ret renderText_multiLine(loadFont_cached(fontName), fontSize, text);
}

static BufferedImage renderText_multiLine(Font font, float fontSize, S text) {
  Color background = optPar(renderText_bg, Color.white);
  Color foreground = optPar(renderText_fg, Color.black);

  font = font.deriveFont(fontSize);
  L<S> lines = toLines(text);
  
  // for font metrics
  BufferedImage dummyImg = new BufferedImage(1, 1, BufferedImage.TYPE_INT_RGB);
  Graphics g = antiAliasGraphics(dummyImg);
  g.setFont(font);
  FontMetrics fm = g.getFontMetrics();
  int width = 0;
  for (S line : lines)
    width = max(width, fm.stringWidth(line));
  if (width <= 0) null;
  int lineHeight = fm.getHeight(); 
  int height = lineHeight*l(lines);
  int y = fm.getAscent();
  
  BufferedImage img = new BufferedImage(width, height, BufferedImage.TYPE_INT_RGB);
    
  g = antiAliasGraphics(img);
  g.setColor(background);

  for i over lines:
    g.drawString(lines.get(i), 0, lineHeight*i+y);
  g.dispose();
