OSG3.0 +cegui0.7.5 结合（支持中文显示）

cegui0.7.5 必须添加代码 setDefaultFont。设置 默认字体。 用0.6的 就没用就可以显示中文...浪费半天时间 惨啊。

也可以改变scheme文件 。。也可以 用代码可以这样写：

    CEGUI::FontManager::getSingleton().createFreeTypeFont("JianTi", 12/*pt*/, true, "msyh.ttf");

    CEGUI::System::getSingleton().setDefaultFont("simfang-12");

全部代码 如下。
