/// [`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.
