/**
 * @class   vtkJSONRenderWindowExporter
 * @brief   Exports a render window for vtk-js
 *
 * vtkJSONRenderWindowExporter constructs a scene graph from an input render
 * window and generates an archive for vtk-js. The traversal of the scene graph
 * topology is handled by graph elements constructed by vtkVtkJSViewNodeFactory,
 * the translation from VTK to vtk-js scene elements (renderers, actors,
 * mappers, etc.) is handled by vtkVtkJSSceneGraphSerializer, and the
 * transcription of data is handled by vtkArchiver. The latter two classes are
 * designed to be extensible via inheritance, and derived instances can be used
 * to modify the vtk-js file format and output mode.
