remove invalid assertion - #6634
...
There is a highly unlikely case where the render thread can have zero
requests in the queue, but it is not supposed to be terminated.
1) WaveView::queue_get_image();
wake up thread, *but* the thread does not start yet
2) WaveView::cancel_my_render_request();
and now the thread starts.
1,2 are initiated by user actions from the GUI thread and are normally
orders of magnitude slower than scheduler-thread wakeup.

Delete a canvas tooltip after we've finished with it
...
All canvas objects share just one tooltip object which is based around Gtk::Label. The Label expands if the current tooltip text is wider than the previous text. However, it doesn't shrink again if the next tooltip has shorter text. Eventually, this results in some very strange looking tooltips (especially in Mixbus where they're used quite extensively).
Deleting the object after use will force a new object to get generated next time (at the correct size). There's still only ever one object per canvas but it's no longer persistent.

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.

Put playhead on top of everything.
...
Achieve this by adding a new hscroll group just for cursors.
That requires a slightly smarter window_to_canvas() to deal with overlapping
sensitive scroll groups. New rule is that scroll groups can overlap, but the
most sensitive one found from the top down will be chosen to translate
coordinates. This basically means don't overlap scroll groups with different
sensitivities.
In the presence of scroll groups, having a canvas-wide window_to_canvas()
and/or canvas_to_window() fundamentally makes no sense. At some point in the
glorious future we should kill those and use only item-relative coordinate
translation.

Search scroll groups for event delivery from top to bottom rather than bottom

the hscroll group (tempo lines) can be below the hvscroll group (tracks), but
the latter gets events.
