6ac68db5be Code cleanup: removed the old real FFT code not used since at least 2009. 
I confirmed that the currently used real FFT code in RealFFTf.cpp is faster
than the old one with a quick benchmark that calls PowerSpectrum() on 4-minute
audio file, with different sizes of computation windows:

Window_size: 256 method: new FFT time_s: 0.393
Window_size: 256 method: old FFT time_s: 1.065
Window_size: 1024 method: new FFT time_s: 0.38
Window_size: 1024 method: old FFT time_s: 0.958
Window_size: 4096 method: new FFT time_s: 0.413
Window_size: 4096 method: old FFT time_s: 1.084
Window_size: 16384 method: new FFT time_s: 0.518
Window_size: 16384 method: old FFT time_s: 1.338
Window_size: 65536 method: new FFT time_s: 0.655
Window_size: 65536 method: old FFT time_s: 1.524
Window_size: 262144 method: new FFT time_s: 0.735
Window_size: 262144 method: old FFT time_s: 1.873

c4f7e25c1c Window function improvemenets: ... 
fix off-by-one inconsistencies in the sum-of-cosines windows.

Implement derivatives of the window functions, needed for reassigned
spectrograms.

9212629945 Added zoom and pan plus fix for bug #884 
It started out as just the fix for #884, but it went
a bit further.  Steve had the idea for the zoom and
pan addition, so I added it while I was working on

6758caa5e1 Make a large number of global variables static so they only have file scope when that is all they need. Part of a patch by Campbell Barton 2013-09-21 19:11:41 +00:00
