The @page rule may contain both 'page-orientation' and 'size' properties. The 'size' property can contain an orientation component which was being represented as 'PageOrientation' prior to this patch. This patch changes that to 'PageSizeOrientation' so that 'PageOrientation' can be used for 'page-orientation' in a subsequent patch.
