/**
 * #GIcon is a very minimal interface for icons. It provides functions
 * for checking the equality of two icons, hashing of icons and
 * serializing an icon to and from strings.
 * 
 * #GIcon does not provide the actual pixmap for the icon as this is out
 * of GIO's scope, however implementations of #GIcon may contain the name
 * of an icon (see #GThemedIcon), or the path to an icon (see #GLoadableIcon).
 * 
 * To obtain a hash of a #GIcon, see g_icon_hash().
 * 
 * To check if two #GIcons are equal, see g_icon_equal().
 * 
 * For serializing a #GIcon, use g_icon_serialize() and
 * g_icon_deserialize().
 * 
 * If you want to consume #GIcon (for example, in a toolkit) you must
 * be prepared to handle at least the three following cases:
 * #GLoadableIcon, #GThemedIcon and #GEmblemedIcon.  It may also make
 * sense to have fast-paths for other cases (like handling #GdkPixbuf
 * directly, for example) but all compliant #GIcon implementations
 * outside of GIO must implement #GLoadableIcon.
 * 
 * If your application or library provides one or more #GIcon
 * implementations you need to ensure that your new implementation also
 * implements #GLoadableIcon.  Additionally, you must provide an
 * implementation of g_icon_serialize() that gives a result that is
 * understood by g_icon_deserialize(), yielding one of the built-in icon
 * types.

	 * native, the returned string is the result of g_file_get_uri()
	 * (such as `sftp://path/to/my%20icon.png`).
	 *
	 * - If @icon is a #GThemedIcon with exactly one name, the encoding is
	 * simply the name (such as `network-server`).
