Log Message:
Changes 1.0.6:
* Now gtk_widget_get_gl_context() doesn't use gtk_quit_add_destroy().
  gtk_quit_add_destroy() cause a problem with recursive main loop.
  OpenGL-capable widget is not destroyed automatically on quit.
* Removed deprecated functions in GTK+-2.3 from example programs.
  gtk_timeout_add()/remove() and gtk_idle_add()/remove() are deprecated
  in GTK+-2.3. Now g_timeout_add() and g_idle_add_full() are used.

Changes 1.0.5:
* Fixed to reduce flickering on resizing OpenGL window.
* Examples have been rewritten to use gdk_window_invalidate_rect()
  and gdk_window_process_updates() instead of gtk_widget_queue_draw().
  Animated OpenGL scene is updated synchronously and immediately.

Changes 1.0.4:
* Added new libglade examples.
* Added new coolwave2.c fullscreen GL application example.
* Minor fix of gtk_widget_set_gl_capability() ("realize" signal \ 
connection).
* Use new function call debug macros.

Changes 1.0.3:
* Added simple GLX_SGIX_pbuffer example.
* Fixed a private header bug in gdk/x11/gdkglx.h and
  gdk/win32/gdkglwin32.h.
* Fixed win32 GLPixmap code that causes GDI error with the latest
  CVS version of GTK+ (>2.2.2).
* gdkgloverlay-x11.c has been rewritten. New code doesn't use
  XSGIFastInternAtom(), so --disable-sgi-fast-atoms configure
  option is no longer needed.
