/**
* 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
* [XSettings](http://www.freedesktop.org/wiki/Specifications/xsettings-spec)
* 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
* `settings.ini` files in
* `/etc/gtk-4.0`, `$XDG_CONFIG_DIRS/gtk-4.0`
* and `$XDG_CONFIG_HOME/gtk-4.0`.
* 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 `settings.ini` file
* next to their `gtk.css` file.
*
* Applications can override system-wide settings by setting the property
* of the GtkSettings object with g_object_set(). 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:
* |[<!-- language="C" -->
* gtk_init (&argc, &argv);
*
* // make sure the type is realized
* g_type_class_unref (g_type_class_ref (GTK_TYPE_IMAGE_MENU_ITEM));
*
* g_object_set (gtk_settings_get_default (), "gtk-enable-animations", FALSE, NULL);
* ]|
*
* 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.
