+This patch removes the dependency on pangox which has been deprecated.  It
+achieves the same result as the upstream patch at 
+https://git.gnome.org/browse/gtkglext/commit/?id=df7a7b35b80b395d7ba411c7f727970a46fb0588
+Like the upstream patch, it removes the functions gdk_gl_font_use_pango_font,
+and gdk_gl_font_use_pango_font_for_display from the API.
