fd2b050d6f Type agnosticism for some other variables that were not sampleCount... 
... in some cases, this fixes narrowings.

79c79f9cd3 Remove many mentions of sampleCount with auto and decltype... 
... This makes much code agnostic about how other things (functions and
arguments) are typed.

Many of these neeed to become size_t instead of sampleCount.

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

48a5f55179 More const qualifiers, for copying of tracks, and replacing in lists of tracks 
... (the tracks may be const, not the list, when replacing)

70c1d57591 More const qualifications, and mutables, for functions that draw tracks... 
... The display related  members that had to become mutable are probably
ones that don't belong in the track classes, ultimately.

adb4a534e8 Pitch is no longer a special view type... && bug fixes 1040, 1041 
... It is a choice of algorithm in spectrogram settings, and any frequency
scale may be chosen with it.  Spectral selection works in it.

97f06ec09c Less shimmer and maybe less CPU in display updates for scroll-scrub, because... 
... tolerant comparison of pps values allows more cache reuse and avoids the
changing alignment of pixels to samples that causes the "shimmery" update.

976eb6164f More reorganization of wave and spectrum caches, and performance... 
Simplify the partial copying of wave and spectrum caches.  Use memcpy for speed.

Don't memcpy out of the caches into temporary buffers for TrackArtist,
just pass
pointers.

More vectors in the cache classes, fewer deletes.

Pulled big loop, and its body, out of the spectrogram routine into functions.
