Changes for 2.1.23
- Added the Arranging Layout extension, demonstrated in the Arranging sample. This layout is basically a layout of layouts, so that you can have a CircularLayout of CircularLayouts, as shown in the sample, or a PackedLayout of TableLayouts, or whatever. The ArrangingLayout also has a third layout that is used to position nodes not arranged by the main layout. This is normally a GridLayout that only positions singleton (disconnected) nodes.
- Improved the ParallelLayout extension and rewrote the Flowgrammer sample to use that ParallelLayout.
- Fixed UndoManager sometimes adding a duplicate "Layout" transaction to the UndoManager.history.
