note about FPS calculation:
1. UnityStats.frameTime, UnityStats.renderTime seem can only be read in OnGUI()
2. the FPS in Profiler(and Unity stats window) seems to match the value (1.0f / (UnityStats.frameTime + UnityStats.renderTime)), not sure but currently my experimental results match the calculation
