QPrintEngine - Switch Windows to QPlatformPrintDevice
Change the Windows QPrintEngine implementation to use the QPlatformPrintDevice to obtain device information, and use QPageSize to obtain page size conversions. A following change will use QPageLayout to store that page size. Change-Id: I990943e2b62ab6dab2c4d4a292c7ed7261beadf2 Reviewed-by: Lars Knoll <lars.knoll@digia.com>bb10
