PostRender
Called to signify all drawing of the display has finished
This handler is called to signify both your handler code and the internal Brass rendering system (part of which includes the drag bar and resize handle) have both finished. It is not legal to perform any drawing in this handler, it is provided for information only. Note that this handler is called as part of the same system (thread) that calls the Render handler, so again you should not perform any lengthy updates or infinite loops.
Parameters
None
