		* rectangle to a buffer and return it via the Surface available from {@link

		* <p>
		* To handle a request, the content should be scrolled to maximize the visible area of the

		* Note: Implementations are only required to render the requested content, and may do so into
		* off-screen buffers without scrolling if they are able.
