Viewport tweaks in XNA Game Studio 4.0

Game Studio 4.0 includes some tweaks to simplify common patterns when working with Viewport objects. We added two constructors:

    public Viewport(int x, int y, int width, int height);
    public Viewport(Rectangle bounds);

And we added a Bounds property to Viewport, Texture2D, and PresentationParameters:

    public Rectangle Viewport.Bounds { get; set; }
    public Rectangle Texture2D.Bounds { get; }
    public Rectangle PresentationParameters.Bounds { get; }

This makes it easier to do things like resetting the viewport to cover the entire surface of a rendertarget:

    GraphicsDevice.Viewport = new Viewport(renderTarget.Bounds);

or scaling a texture to fill the entire viewport:

    spriteBatch.Draw(cat, GraphicsDevice.Viewport.Bounds, Color.White);
