java nifty_jme3与nifty gui1.3结合，修改使其支持中文的输入与显示
1、nifty gui1.3中修改代碼，使其支持中文的輸入：
com.jme3.input.awt.AwtKeyInput類，添加toAWTCode(int key)方法，將jme3中的keyCode轉換成awt中的keyCode：

2、上面只是能接收到中文了，但是仍還不能顯示中文在界面上，下面將渲染包含中文字符在界面上。
在com.jme3.niftygui包中添加類RenderFontAWT：

fontMetrics = image.createGraphics().getFontMetrics(awtFont);
}
@Override
public int getWidth(String text) {
if (text.length() == 0) {
return 0;
}
return fontMetrics.stringWidth(text);
}
@Override
public int getHeight() {
return (fontMetrics.getMaxAscent() + fontMetrics.getMaxDescent());
}
@Override

@Override
