Thanks, Wayne. This API is exactly what I was after.
I also see the visual flickering and sometimes also see the blue square / red circle update again when I interact with a different tool such as switching from the Rectangle to Oval selection tool. It is as if the some clicks are missed and they catch up the next time I interact with the Toolbar?
