annotate widgets/NotifyingCheckBox.h @ 333:e74b56f07c73

* 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.
