[Document.Render obsolete]

Is the entire API documented somewhere?

Or is it all just guess work?

[Document.Render obsolete]

With previous versions of Paint.NET, when you wanted to create a FileType addon, the following code was valid:

protected override void OnSave(Document input, System.IO.Stream output, SaveConfigToken token, Surface scratchSurface, ProgressEventHandler callback)
{
   using (RenderArgs ra = new RenderArgs(new Surface(input.Size)))
   {
       input.Render(ra);             


       var rawData = GetBitmapBytes(ra.Bitmap);
       output.Write(rawData, 0, rawData.Length);
   }
}

Now the Document.Render() method is obsolete and there is a vague reference to PaintDotNet.Rendering.IRenderer<ColorBgra> Document.CreateRenderer() but not documentation on how to use it.

Anybody know how to make the code above work with the new method?
