Visualizer: replace the FFT implementation with a faster one. This implementation uses fixed points instead of floating points. It is slightly inaccurate compared to the old one but still perfect for visualization purpose. It runs 40% faster on passion, 5 times faster on sholes, and of course 14 times faster on sapphire.
