+/**
+ * The <code>Printable</code> interface is implemented
+ * by the <code>print</code> methods of the current
+ * page painter, which is called by the printing
+ * system to render a page.  When building a
+ * {@link Pageable}, pairs of {@link PageFormat}
+ * instances and instances that implement
+ * this interface are used to describe each page. The
+ * instance implementing <code>Printable</code> is called to
+ * print the page's graphics.
+ * <p>
+ * A <code>Printable(..)</code> may be set on a <code>PrinterJob</code>.
+ * When the client subsequently initiates printing by calling
+ * <code>PrinterJob.print(..)</code> control
+ * <p>
+ * is handed to the printing system until all pages have been printed.
+ * It does this by calling <code>Printable.print(..)</code> until
+ * all pages in the document have been printed.
+ * In using the <code>Printable</code> interface the printing
+ * commits to image the contents of a page whenever
+ * requested by the printing system.
+ * <p>
+ * The parameters to <code>Printable.print(..)</code> include a
+ * <code>PageFormat</code> which describes the printable area of
+ * the page, needed for calculating the contents that will fit the
+ * page, and the page index, which specifies the zero-based print
+ * stream index of the requested page.
+ * <p>
+ * For correct printing behaviour, the following points should be
+ * observed:
+ * <ul>
+ * <li> The printing system may request a page index more than once.
+ * On each occasion equal PageFormat parameters will be supplied.
+ *
+ * <li>The printing system will call <code>Printable.print(..)</code>
+ * with page indexes which increase monotonically, although as noted above,
+ * the <code>Printable</code> should expect multiple calls for a page index
+ * and that page indexes may be skipped, when page ranges are specified
+ * by the client, or by a user through a print dialog.
+ *
+ * <li>If multiple collated copies of a document are requested, and the
+ * printer cannot natively support this, then the document may be imaged
+ * multiple times. Printing will start each copy from the lowest print
+ * stream page index page.
+ *
+ * <li>With the exception of re-imaging an entire document for multiple
+ * collated copies, the increasing page index order means that when
+ * page N is requested if a client needs to calculate page break position,
+ * it may safely discard any state related to pages &lt; N, and make current
+ * that for page N. "State" usually is just the calculated position in the
+ * document that corresponds to the start of the page.
+ *
+ * <li>When called by the printing system the <code>Printable</code> must
+ * inspect and honour the supplied PageFormat parameter as well as the
+ * page index.  The format of the page to be drawn is specified by the
+ * supplied PageFormat. The size, orientation and imageable area of the page
+ * is therefore already determined and rendering must be within this
+ * imageable area.
+ * This is key to correct printing behaviour, and it has the
+ * implication that the client has the responsibility of tracking
+ * what content belongs on the specified page.
+ *
+ * <li>When the <code>Printable</code> is obtained from a client-supplied
+ * <code>Pageable</code> then the client may provide different PageFormats
+ * for each page index. Calculations of page breaks must account for this.
+ * </ul>
