31. Why is XtGetValues() on XtNx, XtNy of my top level shell wrong?

----------------------------------------------------------------------

XtNx and XtNy are the coordinates relative to your shell's parent
window, which is usually a window manager's frame window.  To
translate to the root coordinate space, use XtTranslateCoords() or
XTranslateCoordinates().

NOTE: XtTranslateCoords() was broken in releases prior to R4.
