Benjamin Otte e69badbcd1 settings: Keep the GtkSettings object identical no matter the backend 
Previously we were enabling some settings properties only if the X11
backend was enabled. This worked fine with GTK2 where only one backend
was enabled at a time, but now when multiple backends can be enabled,
this does not make sense.

/**
* 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> 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.
