Subject: Add API to convert QSizeF<->PaperSize in QPlatformPrinterSupport
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

These static public functions give printsupport plugins access to the
non-exported qt_paperSizeToQSizeF() and qSizeFTopaperSize() functions in
qprinter.cpp to aid implementing QPrintEngine and
QPlatformPrinterSupport::supportedPaperSizes().
