Should we provide a method similar to DrawingVisual.RenderOpen?

[baochenw]

DrawingVisual in WPF is a lightweight drawing class that is used to render shapes, images, or text. This class is considered lightweight because it does not provide layout, input, focus, or event handling, which improves its performance. For this reason, drawings are ideal for backgrounds and clip art.

I think we can use Visual directly but it seems there is no way to create DrawingContext like as DrawingVisual.RenderOpen.
