// .NAME vtkMRMLAnnotationTextDisplayNode - MRML node to represent display properties for tractography.
// .SECTION Description
// vtkMRMLAnnotationTextDisplayNode 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.
