/**
 * RenderTarget is the graphic container the renderers draw into.
 * <p>
 * There are three types of targets: <b>G2D</b>, <b>PDF</b> or
 * <b>SVG</b>. When the target is G2D, renderers obtain the {@link Graphics2D}
 * object. For the SVG target, renderers obtain Batik's <a
 * href="http://xmlgraphics.apache.org/batik/using/dom-api.html">Document</a>
 * instance. As the PDF target rely on the PDFBox library, renderers obtain the {@link org.apache.pdfbox.pdmodel.PDPageContentStream}</a>
 * object.
 * <p>
 * Render targets are not drawing anything. They just make accessible the canvas
 * renderers can draw into.
 * <p>
 * When render targets have specific properties, values should be set in the
 * {@link PreviewProperties}.
