// map. One might want to turn some of them into propert public API and
// provide a proper alternative for others. See also the exports in
// qapplication_win.cpp which suggest a unification.

    Sets the application override cursor to \a cursor.

    Application override cursors are intended for showing the user
    that the application is in a special state, for example during an
    operation that might take some time.

    This cursor will be displayed in all the application's widgets
    until restoreOverrideCursor() or another setOverrideCursor() is

    Application cursors are stored on an internal stack.
    setOverrideCursor() pushes the cursor onto the stack, and

    corresponding restoreOverrideCursor(), otherwise the stack will
    never be emptied.

    If \a replace is TRUE, the new cursor will replace the last
    override cursor (the stack keeps its depth). If \a replace is
    FALSE, the new stack is pushed onto the top of the stack.

    Example:
    \code
      QApplication::setOverrideCursor( QCursor(Qt::WaitCursor) );
      calculateHugeMandelbrot();              // lunch time...
