      '' GtkGLExt is an OpenGL extension to GTK+. It provides additional GDK
         objects which support OpenGL rendering in GTK+ and GtkWidget API
         add-ons to make GTK+ widgets OpenGL-capable.  In contrast to Janne
         Löf's GtkGLArea, GtkGLExt provides a GtkWidget API that enables
         OpenGL drawing for standard and custom GTK+ widgets.
