/** Looking up icons by name.
 *
 * %Gtk::IconTheme provides a facility for looking up icons by name
 * and size. The main reason for using a name rather than simply
 * providing a filename is to allow different icons to be used
 * depending on what “icon theme” is selected by the user.
 * The operation of icon themes on Linux and Unix follows the
 * [IconPaintable Theme Specification](http://www.freedesktop.org/Standards/icon-theme-spec).
 * There is a fallback icon theme, named `hicolor`, where applications
 * should install their icons, but additional icon themes can be installed
 * as operating system vendors and users choose.
 *
 * In many cases, named themes are used indirectly, via Gtk::Image
 * rather than directly, but looking up icons
 * directly is also simple. The %Gtk::IconTheme object acts
 * as a database of all the icons in the current theme. You
 * can create new %Gtk::IconTheme objects, but it’s much more
 * efficient to use the standard icon theme for the Gdk::Display
 * so that the icon information is shared with other people
 * looking up icons. Use get_for_display().
