Change PANGO_GLYPH_EMPTY to 0x0FFFFFFF, to not overlap with

2006-02-04  Behdad Esfahbod  <behdad@gnome.org>

        * pango/pango-types.h: Change PANGO_GLYPH_EMPTY to 0x0FFFFFFF, to
        not overlap with PANGO_GLYPH_UNKNOWN_FLAG (0x10000000).
        Define PANGO_GET_UNKNOWN_GLYPH(wc) that simply returns
        wc|PANGO_GLYPH_UNKNOWN_FLAG.

        * docs/pango-sections.txt, docs/tmpl/glyphs.sgml: Document new
        symbols.

        * modules/*/*.c: Use PANGO_GET_UNKNOWN_GLYPH instead of various
        backend-specific functions.

        * pango/pangofc-font.c, pango/pangoft.c, pango/pangoxft-font.c,
        * pango/pangowin32.c, pango/pangox.c: Suggest using
        PANGO_GET_UNKNOWN_GLYPH in docs.
