comparison view/ViewManager.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.

+    // always have playback frame aligned against the reference model,
+    // and have the ViewManager know which is the reference model.
+    // That way the ViewManager can assume that all Views report in
+    // reference model timeline, and it can convert the playback frame
+    // received from the play source (which always operates in literal
+    // audio sample frames, i.e. playback model timeline) to the 
+    // reference timeline itself so the view never has to worry about
+    // the difference between playback and reference model.  Of course
+    // that does mean the ViewManager needs to know about both.
