AudioRegionView() c'tor calls create_waves() early on
before the _height is set [1].
Now one following can happen:
1. All peak-files are present. create_waves() directly calls
create_one_wave() for each channel. They are initialized
with zero height.
But all channels are present so waves[] is populated and
a later call to set_height() corrects this
2. All peak-files are still missing. create_waves() schedules
callbacks via PeaksReady -> peaks_ready_handler()
Those callbacks arrive after set_height() was called and
the waveforms are displayed correctly.
3. Only some peak-files are present. This can happen at
rec-stop when the region is created.
create_waves() directly calls create_one_wave() for available
peaks, and schedules peaks_ready_handler() for the remainder.
The directly created waves have zero-height.
Since not all waves are ready, they are stored in tmp_waves.
waves[] remains unpopulated.
The set_height() call only ever changed the height of wave[], which
resulted in hidden waveforms, until a user manually changed the
height of the track.
[1] the height is set from
