     So I added a new method called 'setIgnoreContentScaleFactor' for 'AtlasNode',
     this is not exposed to game developers, it's only used for displaying FPS now.
     
     Secondly, the size of this image is 480*320, to display the FPS label with correct size, 
     a factor of design resolution ratio of 480x320 is also needed.
