This initialization would prevent changing the 'selectbox' type automatically when changing the FLTK scheme. It would also require to set the FLTK scheme *before* the constructor of Fl_Tree_Prefs (i.e. Fl_Tree) is executed which is unexpected and error prone for user code. It is up to the user program to set another boxtype after the constructor if needed.
