* composite.h (enum composition_method): Delete
COMPOSITION_WITH_GLYPH_STRING. (COMPOSITION_METHOD): Dont' check COMPOSITION_WITH_GLYPH_STRING. (Vcomposition_function_table): Extern it. (LGSTRING_XXX, LGLYPH_XXX): Macros moved from font.h. (composition_gstring_put_cache, composition_gstring_from_id) (composition_gstring_p, composition_gstring_width) (composition_compute_stop_pos, composition_reseat_it) (composition_update_it, composition_adjust_point): Extern them. (Fcomposition_get_gstring): EXFUN it.
