options callbacks.
They don't take any argument for the moment, but this will change when
I'm finished with my other vlc changes. There is a little problem: the
Gtk+ interface keeps calling Put***Variable each time we click on "Apply"
or "Save". I think it should only call it once. Is there a way to fix
this? Gildas? lool? :-)
