    /// [`FixedLayout`][crate::FixedLayout] is a layout manager which can place child widgets
    /// at fixed positions.
    ///
    /// Most applications should never use this layout manager; fixed positioning
    /// and sizing requires constant recalculations on where children need to be
    /// positioned and sized. Other layout managers perform this kind of work
    /// internally so that application developers don't need to do it. Specifically,
    /// widgets positioned in a fixed layout manager will need to take into account:
    ///
    /// - Themes, which may change widget sizes.
    ///
    /// - Fonts other than the one you used to write the app will of course
    ///   change the size of widgets containing text; keep in mind that
    ///   users may use a larger font because of difficulty reading the
    ///   default, or they may be using a different OS that provides different
    ///   fonts.
    ///
    /// - Translation of text into other languages changes its size. Also,
    ///   display of non-English text will use a different font in many
    ///   cases.
    ///
    /// In addition, [`FixedLayout`][crate::FixedLayout] does not pay attention to text direction and
    /// thus may produce unwanted results if your app is run under right-to-left
    /// languages such as Hebrew or Arabic. That is: normally GTK will order
    /// containers appropriately depending on the text direction, e.g. to put labels
    /// to the right of the thing they label when using an RTL language;
    /// [`FixedLayout`][crate::FixedLayout] won't be able to do that for you.
    ///
    /// Finally, fixed positioning makes it kind of annoying to add/remove UI
    /// elements, since you have to reposition all the other  elements. This is a
    /// long-term maintenance problem for your application.
    ///
