Gtk+3.0 实现简单的俄罗斯方块

最近学习GTK，顺便就写个小游戏练练手。也是又一个图形界面的小程序啊。不断的学习，才能不断的进步，不知不觉工作之余学习GTK也有几个月了。哈哈。贴上代码，大家共勉啊。

使用方法：

s 左移      f 右移    j 逆时针翻转     l 顺时针翻转      空格加速下降

具体可以参见 response_key_press函数里面的处理过程

代码里面需要完善的地方还是很多的。不过这个也不是很大的项目，也没有一直维护的必要性，也就当练手了。等有了好的项目的话，就上github上弄个站点玩玩。现在就先这样了。有时间继续修改啊。好歹自己在linux下做了个小游戏，闲的无聊了也可以娱乐一下，顺便修改修改，哈哈
