Use the same window manager for freestyle bmain as real bmain uses. This is needed because freestyle's bmain could be used to tag scenes for update, which implies call of ED_render_scene_update in some cases and that function requires proper windoew manager to present. Alternative would be to make render scene update does nothing if there's no window manager, but we wanted freestyle to be applied in rendered viewport once and think current change is what we'll need to support freestyle in viewport. But a bit further, perhaps that'd make sense to not register ED_render_scene_update as a scene update callback when in background mode?
