Here, I am trying out both suggestions:  removing the checkbox from the GUI
and replacing Create+Get with var_InheritInteger.  However, I have a
problem.  Using var_InheritBool instead of Create+Get actually causes the
frequency bands to change when stopping a file and playing it back again
after changing the value in the Preferences window.  This approach proved
very difficult, since I could not find a way to update the frequency labels
in the GUI when VLC enters the "playing" state.  (I tried to implement
several different callbacks in the extended_panels.cpp file with no
success.)  Using the older approach of obtaining the variables (Create+Get)
works, since it requires the user to restart the application, making the
implementation in the GUI easier.  At this point, I am stuck, since it is
undesirable to have incorrect frequency bands in the GUI and it is also
undesirable to use Create+Get.
