Fixes #322174:

2005-11-22  Federico Mena Quintero  <federico@ximian.com>

        Fixes #322174:

        * pango/pangofc-font.h (struct _PangoFcFont): Replace the
        "gpointer context_key" field with "gpointer priv".  This way we
        can access the private data quickly, instead of using
        g_type_instance_get_private().

        * pango/pangofc-private.h: Added prototypes for
        _pango_fc_font_{get,set}_context_key().

        * pango/pangofc-font.c (struct _PangoFcFontPrivate): Moved the
        "context_key" field to here.
        (PANGO_FC_FONT_GET_PRIVATE): Use the "priv" field instead of GType
        private data.
        (pango_fc_font_class_init): Don't register GType private data.
        (pango_fc_font_init): Initialize the private data here.
        (pango_fc_font_finalize): Free the private data.
        (_pango_fc_font_get_context_key): Implement.
        (_pango_fc_font_set_context_key): Implement.
        (pango_fc_font_get_glyph): Remove the g_return_val_if_fail(); it
        was appearing quite high in the profile.

        * pango/pangofc-fontmap.c (pango_fc_font_map_add): Call
        _pango_fc_font_set_context_key() instead of setting the
        fcfont->context_key directly.
        (_pango_fc_font_map_remove): Likewise; also use
        _pango_fc_font_get_context_key() instead of accessing the field
        directly.
