  [UnifiedPDF] Get basic PDF page layout working

Reviewed by Tim Horton and Richard Robinson.

Introduce PDFDocumentLayout for UnifiedPDF, which contains the logic to lay out the PDF
pages, taking page size, rotation and the layout mode into account. Implement basic
single column layout.

Fix PDF page drawing to flip the context when drawing pages.

Hook up an invalidate code path, so that we can repaint the plugin when the PDF loads.
