  #
  # FXPacker is a layout manager which automatically places child windows
  # inside its area against the left, right, top, or bottom side.
  # Each time a child is placed, the remaining space is decreased by the
  # amount of space taken by the child window.
  # The side against which a child is placed is determined by the +LAYOUT_SIDE_TOP+,
  # +LAYOUT_SIDE_BOTTOM+, +LAYOUT_SIDE_LEFT+, and +LAYOUT_SIDE_RIGHT+ hints given by
  # the child window.  Other layout hints from the child are observed as far as
  # sensible.  So for example, a child placed against the right edge can still
  # have +LAYOUT_FILL_Y+ or +LAYOUT_TOP+, and so on.
  # The last child may have both +LAYOUT_FILL_X+ and +LAYOUT_FILL_Y+, in which
  # case it will be placed to take all remaining space.
