diff: -; Mapping from the 68-point ibug annotations to the Surrey DID format (3DMM vertex indices).
  +; Mapping from the 68-point ibug annotations to the Surrey Face Model (SFM) mesh vertex indices.
  ; Note: Points above vertex id 845 are not defined on the reference and thus not available in all model resolutions.
