Waveform: scope-like smooth waveform
* Draw antialised waveform if waveform is monotonic
* Fix center-line position (span at most height - 1),
* Remove invalid "side-lines" that were previously
  drawn around spikes.
* Do not linearly center min/max when drawing log-scale
* Fix offset of lower outline and clip indicators

Remove unused #include<> (2/2)
PBD::stacktrace() is not used nor needed by default.
It should be used sparingly.

Do not show blank waveforms in case height is < 1px
Instead draw some lines to indicate that "something" is there.

Do not bother to render waveforms < 2px high
Those are blank to begin with, nothing is drawn, yet they'd still be
cached.

This may happen during an initial exposure (see 1a49d7d42b),
or when deleting regions.

Fix random off-by-one issue when vertically zooming a waveform
To mitigate concurrent rendering, the waveform cache adds a random
range of pixels centered around the visible waveform.

Alignment is using integer half_width = width_samples / 2;
This always aligns the left-edge to the left-most cairo-pixel.

This fixes an issue with moving moiree patterns in waveforms when
zooming vertically (which invalidates the cache and uses a
different random number of pixels),

30b087ab3d globally change all use of "frame" to refer to audio into "sample".
Generated by tools/f2s. Some hand-editing will be required in a few places to fix up comments related to timecode
and video in order to keep the legible

beb73edf55 Purify libcanvas, remove libardour dependency
A canvas is just a canvas. Move WaveView into its own library.
