#### JavaScript Performance Monitor

This library provides an info box that will help you monitor your code performance.

- **FPS** Frames rendered in the last second. The higher the number the better.
- **MS** Milliseconds needed to render a frame. The lower the number the better.
- **MB** MBytes of allocated memory. (Run Chrome with `--enable-precise-memory-info`)
- **DC** Draw Calls made within one frame.
- **TC** Texture Count used within one frame.
- **CUSTOM** User-defined panel support.
