camera windows (and maybe mac) at open preferences, combo does not mark current
Seems it is a difference of:
combo has the fullnames: UtilGtk.ComboUpdate(combo_camera, wd_list.GetFullnames());
but active is the current: combo_camera.Active = UtilGtk.ComboMakeActive(combo_camera, current);
and current is a preferences.videoDevice
so check if we need to convert code to fullname or viceversa
