Previously SpinBox did not update on return or changes to the editor. The widget had to lose focus or be manually incremented. This lets the editor update on return and now always displays the most recent clamped value. set_value_from_current_text() will also be useful to programmatically set SpinBox within layouts whose default buttons consume return key presses.
