Allow the surface to resized based on layout of its container (this is the default). When this is enabled, you should monitor ISurfaceHolderCallback.SurfaceChanged(ISurfaceHolder, Android.Graphics.Format, Android.Graphics.Format, Android.Graphics.Format) for changes to the size of the surface. When working with a Android.Views.SurfaceView, this must be called from the same thread running the SurfaceView's window.
