Firstly, we need to ignore 'contentScaleFactor' in 'CCAtlasNode' and 'CCLabelAtlas'.
So I added a new method called 'setIgnoreContentScaleFactor' for 'CCAtlasNode',
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.
