[gtk+/composite-templates-new: 7/26] Added directory with Glade catalog

[Tristan Van Berkom <tvb src gnome org>]

commit afa45614183ee573d59f04935a5697c5bd7be5c6
Author: Tristan Van Berkom <tristanvb openismus com>
Date:   Mon Mar 25 01:40:57 2013 +0900

    Added directory with Glade catalog
    
    This catalog can be used to work with GTK+'s private widget types,
    this patch exposes a private function gtk_glade_catalog_init() which
    Glade will use for the sole purpose of initializing some private widget
    types in GTK+ that are referenced from various GTK+ composite widget
    xml files.

+The catalog in this directory defines some widgets that are private
+to GTK+ and is needed to edit .ui files defining composite classes
+in GTK+.
+
+In order to edit any composite classes in GTK+, startup Glade
+in the following way, example:
+
+    cd /path/to/gtk+/
+    GLADE_CATALOG_SEARCH_PATH=`pwd`/gtk/glade glade gtk/gtkfilechooserdefault.ui
+
+Documentation for updating this catalog can be found here:
+    https://developer.gnome.org/gladeui/stable/
+
+Note also that when including private GTK+ widgets as components, it is
+important to call g_type_ensure () to register the type explicitly
+before calling gtk_container_init_template(), otherwise GtkBuilder will
+not be able to properly load the type.
