* 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.
