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

Rebasing the feature branch against master was too messy, and only these two files were
changed. The development history of this branch could easily have been --squash'ed anyway,
so not much of a loss

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.

In summary:
* no antialiasing of waveviews
* no diagonal lines
* simplify clip detection
* don't use LINE_CAP_ROUND for outline
