/**
* SECTION:gtksettings
* @Short_description: Sharing settings between applications
* @Title: Settings
*
* GtkSettings provide a mechanism to share global settings between
* applications.
*
* On the X window system, this sharing is realized by an
* <ulink url="http://www.freedesktop.org/wiki/Specifications/xsettings-spec">XSettings</ulink>
* manager that is usually part of the desktop environment, along with
* utilities that let the user change these settings. In the absence of
* an Xsettings manager, GTK+ reads default values for settings from
* <filename>settings.ini</filename> files in
* <filename>/etc/gtk-3.0</filename>, <filename>$XDG_CONFIG_DIRS/gtk-3.0</filename>
* and <filename>$XDG_CONFIG_HOME/gtk-3.0</filename>.
* These files must be valid key files (see #GKeyFile), and have
* a section called Settings. Themes can also provide default values
* for settings by installing a <filename>settings.ini</filename> file
* next to their <filename>gtk.css</filename> file.
*
* Applications can override system-wide settings with
* gtk_settings_set_string_property(), gtk_settings_set_long_property(),
* etc. This should be restricted to special cases though; GtkSettings are
* not meant as an application configuration facility. When doing so, you
* need to be aware that settings that are specific to individual widgets
* may not be available before the widget type has been realized at least
* once. The following example demonstrates a way to do this:
* <informalexample><programlisting>
* gtk_init (&argc, &argv);
*
* /&ast; make sure the type is realized &ast;/
* g_type_class_unref (g_type_class_ref (GTK_TYPE_IMAGE_MENU_ITEM));
*
* g_object_set (gtk_settings_get_default (), "gtk-menu-images", FALSE, NULL);
* </programlisting></informalexample>
*
* There is one GtkSettings instance per screen. It can be obtained with
* gtk_settings_get_for_screen(), but in many cases, it is more convenient
* to use gtk_widget_get_settings(). gtk_settings_get_default() returns the
* GtkSettings instance for the default screen.
