48a5f55179 More const qualifiers, for copying of tracks, and replacing in lists of tracks

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.

952a22c8b1 Created a global structure to hold spectrogram preferences... 
Don't read "/Spectrum/" preferences anywhere but in SpectrumPrefs.cpp.
Don't store global values in TrackArtist.

Possibly some day, there will be other instances of SpectrogramSettings so we
can have independent per-track settings.

38f24a42ef Don't invalidate SpecCache for changes of min, max, gain or range...

e6ccd51326 Use WaveTrackCache for spectrograms 
Zooming-in of spectrograms (or other view changes that invalidate the
whole pixel cache of the WaveClip) used to do at least one opening and
closing of a block file for each column of pixels.  With this change,
open each block file not more than once for each repopulation of the
cache.

Improved speed may be more noticeable on less powerful computers, or when
the audio file is in a slower storage device.

8bcec00e65 Rewrite Sequence::GetWaveDisplay 
That is the function that computes the heights of dark and pale blue lines in
the waveform display.

It's not simple but now the flow of control is less strange and it is better
commented.

This doesn't fix or enhance anything, but it might find use later, such as in
a project to adapt the resolution of the display in reponse to slow scrolling
updates.

cc2a26956a Fix display caching for waveforms and spectrograms so smooth scrolling works 
This will matter if the smooth-scrolling version of scrubbing is enabled

The problem was accumulation of roundoff errors when deciding which pixel
column data to copy from old caches to new caches, when the number of samples
scrolled was not an integer multiple of samples per pixel (itself, not always
an integer)

Thus repeated scrolling by small amounts caused the wave display or spectrogram
to creep relative to the time ruler!
