Class structure for #GtkEntry. All virtual functions have a default
implementation. Derived classes may set the virtual function pointers for the
signal handlers to %NULL, but must keep @get_text_area_size and
@get_frame_size non-%NULL; either use the default implementation, or provide
a custom one.
