}Invalidator lets background goroutines ask the window to repaint. Create one, pass it as Config.Invalidator, and call Invalidate from anywhere after the goroutine has published its result. It owns no goroutine, timer, or channel: an application that never calls Invalidate pays nothing, and the window thread is woken exactly once per call batch.
Calls made before RunCanvas starts or after the window closes do nothing. The zero value is ready to use.
