 * SECTION:gdk-pixbuf-xlib-init
 * @Short_description: Initializing the gdk-pixbuf Xlib library.
 * @Title: gdk-pixbuf Xlib initialization
 * @See_also:    XlibRGB
 * 
 * In addition to the normal Gdk-specific functions, the &gdk-pixbuf;
 * package provides a small library that lets Xlib-only applications
 * use #GdkPixbuf structures and render them to X drawables.  The
 * functions in this section are used to initialize the &gdk-pixbuf;
 * Xlib library.  This library must be initialized near the beginning
 * of the program or before calling any of the other &gdk-pixbuf;
 * Xlib functions.
