//创意来自 gpu-accelerated-flash-player 扩展！
//是否有加速效果作者也不知道。
//关于wmode参数的解释：http://helpx.adobe.com/flash/kb/flash-object-embed-tag-attributes.html
//如果你使用的是firefox，可以在about:config将plugins.force.wmode修改(新建)为 gpu 或 direct
//
var run_time_max = 3; //最大运行次数
var wmode_value = 'gpu'; //默认 gpu，可以是 direct。一般不需要更改
