          Parameters
          ----------
          frame_no : int
              The frame of data where we should reposition marker bodies. Markers
              will be positioned in the appropriate places in world coordinates.
              In addition, linear velocities of the markers will be set according
              to the data as long as there are no dropouts in neighboring frames.
