docs: Replies the bounds of the area covered by the node and normalize it to
  fit as well as possible the coordinates of the given reference.
  The normalization is done by {@link #normalize(Rectangle2d, Rectangle2afp)}.
  
  @param node is the node for which the bounds must be extracted and reploed.
  @param reference is the bounding object which is the reference for the normalization.
  @return the normalized rectangle.
