27  * This interface allows the user of the Graphics2D SVG generator
28  * to decide how to handle images that it renders. For example,
29  * an implementation could decide to embed JPEG/PNG encoded images
30  * into SVG source document using the data protocol (RFC 1521, paragraph 5.2)
31  * Another option is to save images into JPEG/PNG files and store URI
32  * in SVG source. <br>
