* Some work on correct alignment when moving panes during playback
* Overhaul alignment for playback frame values (view manager now always
  refers to reference-timeline values, only the play source deals in
  playback model timeline values)
* When making a selection, ensure the selection regions shown in other
  panes (and used for playback constraints if appropriate) are aligned
  correctly.  This may be the coolest feature ever implemented in any
  program ever.
