// .NAME vtkMRMLAnnotationPointDisplayNode - MRML node to represent display properties for tractography.
// .SECTION Description
// vtkMRMLAnnotationPointDisplayNode nodes store display properties of trajectories 
// from tractography in diffusion MRI data, including color type (by bundle, by fiber, 
// or by scalar invariants), display on/off for tensor glyphs and display of 
// trajectory as a line or tube.
