Summary	0000589: Redraw render texture with API call instead of each frame
Description	Currently a render texture is redrawn each frame, even if nothing changes. This is wasteful of resources, especially on mobile. It would be great if you can provide an API similar to Camera.Render() so it is possible to "freeze" rendering and only render when you know something has changed.
Steps To Reproduce	N/A

Platform	Any

Also, we are exposing a new method in NoesisView, NeedsRendering() that can be used in manually repainted cameras to do manual Camera.Render(). Thanks for your feedback!
