docs: Return the shape clipped to a clip_factor expansion of buffer_padded_bounds
      if is_clipped is True. Otherwise return the original shape, or None if the
      shape does not intersect buffer_padded_bounds at all.
  
      This is used to reduce the size of the geometries which are encoded in the
      tiles by removing things which aren't in the tile, and clipping those which
      are to the clip_factor expanded bounding box.
