-/** @struct NodeTool
- *
- * Node tool event context.
- *
- * @par Architectural overview of the tool
- * @par
- * Here's a breakdown of what each object does.
- * - Handle: shows a handle and keeps the node type constraint (smooth / symmetric) by updating
- *   the other handle's position when dragged. Its move() method cannot violate the constraints.
- * - Node: keeps node type constraints for auto nodes and smooth nodes at ends of linear segments.
- *   Its move() method cannot violate constraints. Handles linear grow and dispatches spatial grow
- *   to MultiPathManipulator. Keeps a reference to its NodeList.
- * - NodeList: exposes an iterator-based interface to nodes. It is possible to obtain an iterator
- *   to a node from the node. Keeps a reference to its SubpathList.
- * - SubpathList: list of NodeLists that represents an editable pathvector. Keeps a reference
- *   to its PathManipulator.
- * - PathManipulator: performs most of the single-path actions like reverse subpaths,
- *   delete segment, shift selection, etc. Keeps a reference to MultiPathManipulator.
- * - MultiPathManipulator: performs additional operations for actions that are not per-path,
- *   for example node joins and segment joins. Tracks the control transforms for PMs that edit
- *   clipping paths and masks. It is more or less equivalent to ShapeEditor and in the future
- *   it might handle all shapes. Handles XML commit of actions that affect all paths or
- *   the node selection and removes PathManipulators that have no nodes left after e.g. node
- *   deletes.
- * - ControlPointSelection: keeps track of node selection and a set of nodes that can potentially
- *   be selected. There can be more than one selection. Performs actions that require no
- *   knowledge about the path, only about the nodes, like dragging and transforms. It is not
- *   specific to nodes and can accomodate any control point derived from SelectableControlPoint.
- *   Transforms nodes in response to transform handle events.
- * - TransformHandleSet: displays nodeset transform handles and emits transform events. The aim
- *   is to eventually use a common class for object and control point transforms.
- * - SelectableControlPoint: base for any type of selectable point. It can belong to only one
- *   selection.
- *
- * @par Functionality that resides in weird places
- * @par
- *
- * This list is probably incomplete.
- * - Curve dragging: CurveDragPoint, controlled by PathManipulator
- * - Single handle shortcuts: MultiPathManipulator::event(), ModifierTracker
- * - Linear and spatial grow: Node, spatial grow routed to ControlPointSelection
- * - Committing handle actions performed with the mouse: PathManipulator
- * - Sculpting: ControlPointSelection
- *
- * @par Plans for the future
- * @par
- * - MultiPathManipulator should become a generic shape editor that manages all active manipulator,
- *   more or less like the old ShapeEditor.
- * - Knotholder should be rewritten into one manipulator class per shape, using the control point
- *   classes. Interesting features like dragging rectangle sides could be added along the way.
- * - Better handling of clip and mask editing, particularly in response to undo.
- * - High level refactoring of the event context hierarchy. All aspects of tools, like toolbox
- *   controls, icons, event handling should be collected in one class, though each aspect
- *   of a tool might be in an separate class for better modularity. The long term goal is to allow
- *   tools to be defined in extensions or shared library plugins.
