    Most often overlooked "feature" of XmDialogShell is the fact it
    IGNORES x,y values set by the user for the *shell*, and uses
    the x,y specified for it's *child*, i.e. manager widget.
    
    The "feature" comes from XUI's decision to *hide shells*, i.e. make
    the programmer *unaware* of the shell presence. Wheather it was the
    best descision ... Note the use of the child's x,y for the shell's
    position also implies several hacks for get values ...

    To OSF: (just a minor proposal)
    May be, the XmDialogShell should default to "Xm_UNSPECIFIED_POSITION"
    for x,y; meaning "use child's x,y instead". The same should apply for
    shell width,height.
    If the user has specified x,y for the shell, i.e. it is no more
    "Xm_UNSPECIFIED_POSITION", the shell could behave like any normal,
    good behaving Xt shell.
    This would preserve functionality for those who like/depend upon XUI
    style of "hidden things", but also eliminate confusion for those
    who know (or believe to know) what the shell is for.
