... Move some fields used only during formatting into a temporary structure.
(And fixing a minor problem with uninitialized variables in case of logarithmic
scale, which made it unpredictable how Plot Spectrum with logarithmic
frequencely axis formatted numbers.)
... and also draw the zeroes if in range, taking precedence over the extreme
values (which might be positive dB values when zoomed out or scrolled).

Whatever change it is that needs loading by LoadPrefs -- do it instead right
after any possibility of changes to the relevant preferences, in the Commit()
functions of SpectrumPrefs and WaveforPrefs

This will allow easier, non-intrusive addition of other kinds of track
visualizations.

Instead, discover them through a registry.
This eliminates some duplication of string constants and prepares for

This makes the command agnostic about which subview types are known, but the

Only distinguish Waveform and Spectrogram and nil.

2. With the new behaviour, scrubbing immediately changes direction, and does not stop when the original key is released - scrubbing does not stop and then start again.
New behaviour:
