In the case where the layout phase queued a layout we don't want to progress to the paint phase with invalid allocations, so we loop the layout. This shouldn't normally happen, but it may happen in some edge cases like if user/wm resizes clash with natural window size changes from a gtk widget. This should not generally loop though, so we detect this after 4 cycles and print a warning. This was detected because of an issue in GtkWindow where it seems to incorrectly handle the case of a user interactive resize. It seems gtk_window_move_resize() believes that configure_request_size_changed changed due to hitting some corner case so it calls gtk_widget_queue_resize_no_redraw(), marking the window as need_alloc after the layout phase. This commit fixes the issue, but we should also look into if we can fix that.
