 * Class SCH_BASE_FRAME
 * is a shim class between EDA_DRAW_FRAME and several derived classes:
 * LIB_EDIT_FRAME, LIB_VIEW_FRAME, and SCH_EDIT_FRAME, and it brings in a
 * common way of handling the provided virtual functions for the derived classes.
 * <p>
 * The motivation here is to switch onto GetScreen() for the underlying data model.
