Match up the specified paper size to an existing one if possible
When EnumForms was used then the dmPaperSize was not always correct for the custom paper sizes available on some printers. By using DeviceCapabilities we can be sure that the information is correct in this respect. This also fixes respecting of the custom paper size if one is given and there is no corresponding existing paper size for it. Task-number: QTBUG-34276 Change-Id: I9924d5be8527027fc434261e37f6c7aae66210c3 Reviewed-by: Friedemann Kleint <Friedemann.Kleint@digia.com>
