            var         surface = drawable.CreateSurface(Bounds, Window.BackingScaleFactor, out info);

            // draw on the image using SKiaSharp
            DrawInSurface(surface, info);

            // draw the surface to the context
            drawable.DrawSurface(ctx, Bounds, info, surface);
