This helper remembers a DialControl for entering a rotation angle, and a
check box for stacked text, that enables/disables other controls dependent
on its state.
It is possible to register more controls that have to be enabled/disabled
together with this helper object (optionally dependent on the stacked text
check box), using the function AddDependentWindow(). All registered windows
are handled on a call of Enable(), or Show(), or on changing the state of
the "Stacked text" check box.
Note: The member function SetStackedState() should be used instead of
direct modifications of the "Stacked text" check box. Otherwise the update
mechanism of registered controls will not work.
