Problem with custom paper sizes

Problem with custom paper sizes

Steps to reproduce / test case
1) Open fontsampler example
2) Open print preview dialog
3) Open page setup dialog
4) Select A0 paper size and Landscape orientation ( I can reproduce it also on A1, A10 sizes )
5) Click OK button

You may see that print preview dialog shows Portrait orientation.
More information
I have found that in QWin32PrintEnginePrivate::updateCustomPaperSize width and height taken from FORM_INFO_1 are always returned in "portrait sizes" (width < height), but I couldn't find if they are swapped in case of orientation. I use PdfCreator for testing printing.
