/**
* Here is a two page example with header, footer and logo:
*
* This example makes use of the Header() and Footer() methods to process page
* headers and footers. They are called automatically. They already exist in the
* wxPdfDocument class but do nothing, therefore we have to extend the class and override
* them.
*
* The logo is printed with the Image() method by specifying its upper-left corner
* and its width. The height is calculated automatically to respect the image
* proportions.
*
* To print the page number, a null value is passed as the cell width. It means
* that the cell should extend up to the right margin of the page; it is handy to
* center text. The current page number is returned by the PageNo() method; as for
* the total number of pages, it is obtained by means of the special value {nb}
* which will be substituted on document closure (provided you first called
* AliasNbPages()).
*
* Note the use of the SetY() method which allows to set position at an absolute
* location in the page, starting from the top or the bottom.

* Another interesting feature is used here: the automatic page breaking. As soon
* as a cell would cross a limit in the page (at 2 centimeters from the bottom by
* default), a break is performed and the font restored. Although the header and
* footer select their own font (Helvetica), the body continues with Times. This mechanism
* of automatic restoration also applies to colors and line width. The limit which
* triggers page breaks can be set with SetAutoPageBreak().
