PrintOptions is a QWidget class to be used as an
addition to a future print dialog (possibly based on
QPrintDialog). Currently only contains a couple of
radio buttons.
PrintDialog (printdialog.cpp/h) which is a basic QDialog
is currently added for testing only and it holds
an instance of PrintOptions.
Calling File->Print opens this test dialog for now.
