Window.freezeToplevelUpdatesLibgtkOnly

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.Window.thawToplevelUpdatesLibgtkOnly] is called. If [gdk.window.Window.freezeToplevelUpdatesLibgtkOnly] has been called more than once, [gdk.window.Window.thawToplevelUpdatesLibgtkOnly] 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+.
