@Override
public void copyArea(int x, int y, int width, int height, int dx, int dy) {
    // glRasterPos* is transformed, but CopyPixels is not
    int x2 = x + dx;
    int y2 = y + dy + height;
    GL11.glRasterPos2i(x2, y2);//w  ww. ja  va  2  s.c o  m

    int x1 = x;
    int y1 = g2d.getCanvasHeight() - (y + height);
    GL11.glCopyPixels(x1, y1, width, height, GL11.GL_COLOR);
