do not draw waveform outline at x-positions where the waveform "spread" would not leave at least 1 pixel between the two outline pixels.

stop pixel jitter when changing waveview height.
...
To avoid pixel jitter, the top and bottom of each line in the waveview must be computed together in a single computation,
rather than independently.
Also, remove various height corrections and cairo translations that are not necessary or relevant anymore. A subsequent
commit for the GUI will pick up on this work to get the appearance completely correct

changed. The development history of this branch could easily have been --squash'ed anyway,

For the canvas library, #include 'gtkmm2ext/gui_thread.h' rather than 'gtk2_ardour/gui_thread.h'
...
Technically it doesn't make much difference but from what I can tell, the only files which #include 'gtk2_ardour/gui_thread.h' are the source files from gtk2_ardour itself. The support libraries always #include 'gtkmm2ext/gui_thread.h' directly (which seems sensible). So for consistency's sake, let's keep it the same for libcanvas.

Manual merge of the drawing component of waveview branch.

In summary:
* no antialiasing of waveviews
* no diagonal lines
* simplify clip detection
* don't use LINE_CAP_ROUND for outline
* use the wave colour when drawing outline only

completely rethink waveform rendering (again)
...
There are 3 possible components to draw at each x-axis position: the waveform "line", the zero line and an outline/clip indicator.
We have to decide which of the 3 to draw at each position, pixel by pixel. This makes the rendering less efficient but it is
the only way I can see to do this correctly.
