/**
    @class wxPageSetupDialog

    This class represents the page setup common dialog.

    The page setup dialog contains controls for paper size (letter, A4, A5 etc.),
    orientation (landscape or portrait), and, only under Windows currently,
    controls for setting left, top, right and bottom margin sizes in millimetres.

    The exact appearance of this dialog varies among the platforms as a native
    dialog is used when available (currently the case for all major platforms).

    When the dialog has been closed, you need to query the wxPageSetupDialogData
    object associated with the dialog.

    Note that the OK and Cancel buttons do not destroy the dialog; this must be done
    by the application.
