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.
