    /// For most applications, you should not use this container! It keeps
    /// you from having to learn about the other GTK containers, but it
    /// results in broken applications. With [`Fixed`][crate::Fixed], the following
    /// things will result in truncated text, overlapping widgets, and
    /// other display bugs:
    ///
    /// - 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, [`Fixed`][crate::Fixed] 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 for the text direction, e.g. to put labels to
    /// the right of the thing they label when using an RTL language, but it can’t
    /// do that with [`Fixed`][crate::Fixed]. So if you need to reorder widgets depending on
    /// the text direction, you would need to manually detect it and adjust child
    /// positions accordingly.
    ///
    /// 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.
    ///
    /// If you know none of these things are an issue for your application,
    /// and prefer the simplicity of [`Fixed`][crate::Fixed], by all means use the
    /// widget. But you should be aware of the tradeoffs.
