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 Window.thawToplevelUpdatesLibgtkOnly is called. If Window.freezeToplevelUpdatesLibgtkOnly
has been called more than once, Window.thawToplevelUpdatesLibgtkOnly must be called an equal number of times to begin processing exposes.
