Use to force the radial gauge to finish any deferred work before printing or evaluating its visual. This should only be called if the visual of the radial gauge needs to be synchronously saved or evaluated. Calling this method too often will hinder the performance of the radial gauge.
Optional getRuns before React applies the result of render to the document, and
returns an object to be given to componentDidUpdate. Useful for saving
things such as scroll position before render causes changes to it.
Note: the presence of getSnapshotBeforeUpdate prevents any of the deprecated lifecycle events from running.
