GeneratorPDF class. Adapted the whole KPDFLink class to a hieracy of classes and added a Viewport description associated to 'Goto' links. Link hasn't got geometry properties. A PageRect class has born to describe all 'active rects' on a page (hand pointed on mouse over). PageRect can contain many type of objects such as Links or other active items (images, ...). The Page class now stores PageRects only (no more geometric Links, as already said). Added a DocumentInfo class filled in by generators and used by the PropertiesDialog. Outline hasn't been abstracted while now, but a DocumentSynopsis class is in place and work needs to be done to make GeneratorPDF fill in a DocumentSynopsis instance and pass it to the Toc widget. Note1: Document has nothing more to do with xpdf, it only commands its generator. Note2: 2 remaining classes to be abstracted: Outline, TextPage. But waning.. svn path=/branches/kpdf_experiments/kdegraphics/kpdf/; revision=369651
