Mr.doob的stats.as，检测内存，FPS等。

貘良了

FPS Frames per second, how many frames were rendered in 1 second, the bigger the better.
MS Milliseconds needed to render a frame, the lower the better.
MEM Memory your code is using, if it increases per frame is VERY wrong.
MAX Maximum memory the application reached.
