Adds a usePageRuleSizeAsPaperSize setting to allow overriding the default paper size when printing to a PDF file. Print preview now checks for at-page size rules and when enabled will use that size for the previewed sheet of paper. The preview will also return the page width and height (in inches) during its callback for the frontend to use to override the default paper settings.
