Backdrop : Added a dedicated title bar for selection and moving Backdrops. This is smaller but more obvious than the previous region, reducing the likelihood of accidental movement.
NodeEditor : Added Alt+E and Alt+Shift+E shortcuts for editing source and tweak nodes respectively. These are similar to the equivalent shortcuts in the Viewer and HierarchyView, but pin an existing NodeEditor instead of creating a new one.
Animation : Added compatibility for loading animation from Gaffer 0.61 where Step has been renamed to Constant.
PrimitiveInspector : Fixed update when all primitive variables with a particular interpolation are removed.
