/** A container which allows you to position widgets at fixed coordinates.
 *
 * The Gtk::Fixed widget is a container which can place child widgets at fixed positions and with fixed sizes, given in pixels. It performs no automatic layout management.
 * For most applications, you should not use this container, because it will result in truncated text, overlapping widgets, and other display bugs:
 * - Themes 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 Windows or the framebuffer port of GTK+, where different fonts are available.
 * - 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, the fixed widget can't properly be mirrored in right-to-left languages such as Hebrew and Arabic. i.e. normally GTK+ will flip the interface to put labels to the right of the thing they label, but it can't do that with Gtk::Fixed. So your application will not be usable in right-to-left languages.
 * Finally, fixed positioning makes it kind of annoying to add/remove GUI 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 Gtk::Fixed, by all means use the widget. But you should be aware of the tradeoffs.
