GdkWindowfreeze_toplevel_updates_libgtk_only

Temporarily freezes a window and all its descendants such that it won’t receive expose events. The window will begin receiving expose events again when gdk_window_thaw_toplevel_updates_libgtk_only() is called. If gdk_window_freeze_toplevel_updates_libgtk_only() has been called more than once, gdk_window_thaw_toplevel_updates_libgtk_only() must be called an equal number of times to begin processing exposes.

This function is not part of the GDK public API and is only for use by GTK+.
