update_video_timeline() is called after destroying the
video_timeline instance at exit.

During ARDOUR_UI::finish(), after destroying various instances:
close_all_dialogs() -> ArdourDialog::on_response() -> GUIIdle()
The event loop recurses and may execute a previously scheduled
Editor::idle_visual_changer()
Best guess right now is that optimization does something bad when ceil() is called twice on a very large dbl-precision number,
which results in a zero (empty) redraw area. Without the removal of the redundant ceil & floor functions, no expose events
would be delivered to the canvas in an optimized build during drags (and maybe more).
when using ImportDistinctChannels, correctly name regions so that playlists for each channel/track
are also named differently, and thus reloaded properly when the session is reloaded.

timeline thumbnail display, moving (drag/drop) and zoom works.
There still some crashes e.g. resizing the height of the timeline
and with off-screen image buffering when zooming in.
Likely due to concurrency issues:
VideoImageFrame::exposeimg() and direct access of the pixbuf:
"Assertion `!_bounding_box_dirty' failed." in canvas/item.cc:191
more work is needed..
When extracting and importing audio from a video,
mark the audio region's position as locked to the
video.
While locked, the audio region can only be moved
by moving the video with a granularity of one Timecode
frame.
