      Allocates a display configuration object populated with data from the
      OSVR system.
      Before this call will succeed, your application will need to be correctly
      and fully connected to an OSVR server. You may consider putting this call in
      a loop alternating with osvrClientUpdate() until this call succeeds.
      Data provided by a display configuration object:
      - The logical display topology (number and relationship of viewers, eyes,
      and surfaces), which remains constant throughout the life of the
      configuration object. (A method of notification of change here is TBD).
      - Pose data for viewers (not required for rendering) and pose/view data for
      eyes (used for rendering) which is based on tracker data: if used, these
      should be queried every frame.
      - Projection matrix data for surfaces, which while in current practice may
      be relatively unchanging, we are not guaranteeing them to be constant:
      these should be queried every frame.
      - Video-input-relative viewport size/location for a surface: would like this
      to be variable, but probably not feasible. If you have input, please
      comment on the dev mailing list.
      - Per-surface distortion strategy priorities/availabilities: constant. Note
      the following, though...
      - Per-surface distortion strategy parameters: variable, request each frame.
      (Could make constant with a notification if needed?)
      Important note: While most of this data is immediately available if you are
      successful in getting a display config object, the pose-based data (viewer
      pose, eye pose, eye view matrix) needs tracker state, so at least one (and in
      practice, typically more) osvrClientUpdate() must be performed before a new
      tracker report is available to populate that state. See
      osvrClientCheckDisplayStartup() to query if all startup data is available.
      todo Decide if relative viewport should be constant in a display config,

      described, or if invalid parameters were passed, in which case the output
      argument is unmodified.

      public static byte osvrClientGetViewerEyeSurfaceRadialDistortion(OsvrDisplayLibrary.OSVR_DisplayConfig disp, int viewer, byte eye, int surface, com.sun.jna.Pointer params)
      Returns the radial distortion parameters, if known/requested, for a
      surface seen by an eye of a viewer in a display config.
      Will only succeed if osvrClientGetViewerEyeSurfaceRadialDistortionPriority()
      reports a non-negative priority.
      Parameters:
      disp - Display config object
      viewer - Viewer ID
      eye - Eye ID
      surface - Surface ID
      params - Output: the parameters for radial distortion
      Returns:
      OSVR_RETURN_FAILURE if this surface does not have these parameters
      described, or if invalid parameters were passed, in which case the output
      argument is unmodified.
