1)笔记

1)什么是fps?
  (1)计算机是一个离散的世界,每隔一段时间绘制一下这个世界的样子,再隔一段时间,
     再绘制一下世界的样子,再绘制一下世界的样子...如果绘制的间隔足够小,那么人
     眼则认为它是连续的;

  (2)游戏每间隔一段时间不断刷新画面,驱动游戏世界往前走, FPS: frame per second
     每秒刷新多少次;

2)FPS形象举例: 从A到B点,帧率高的绘制次数就多,过程中的状态,次数就多一点,这个动
  画看上去就流畅一点,所以fps是衡量游戏运行流畅程度的一个表示;

3)Update函数: 每一次游戏刷新的时候,会被调用,所以我们要统计帧率是多少,
  我们就要在Update中累计一段时间之内,我们刷过的帧的次数,到时候我们显示
  帧率的时候,把这个fps挂到这个根节点上;

4)fps算法: 在固定的一段时间内,累计刷新的帧数,当世间到了后,算出fps,并显示出来;

5)OnGUI: 每次在GUI刷新的时候调用;
  (0,0)是左上角开始的;
