21 Generate an centred extender. Should make a Extender_spanner that
22 typesets a nice centred extender of varying length depending on the
23 gap between syllables.
25 We remember the last Text_item that come across. When we get a
26 request, we create the spanner, and attach the left point to the
27 last lyrics, and the right point to any lyrics we receive by
29 class Extender_engraver : public Engraver
