2006-02-02 Behdad Esfahbod <behdad@gnome.org>
Finish the 'glyph 0' work of this morning:
PANGO_GLYPH_NULL that I introduced is renamed to
PANGO_GLYPH_EMPTY. It means, no rendering should
be performed. The backends however, still return
0 if a glyph is not found. The modules then are
free to replace this 0 glyph with an unknown
character.
* modules/arabic/arabic-fc.c, modules/basic/basic-atsui.c,
modules/basic/basic-fc.c, modules/basic/basic-win32.c,
modules/basic/basic-x.c, modules/hangul/hangul-fc.c,
modules/hebrew/hebrew-fc.c, modules/indic/indic-fc.c,
modules/khmer/khmer-fc.c, modules/syriac/syriac-fc.c,
modules/thai/thai-fc.c, modules/tibetan/tibetan-fc.c,
pango/pangox.c, pango/pangowin32.c:
Adapt to above change. Backends return 0 if glyph not
found.
* pango/fonts.c (pango_font_get_glyph_extents): If font
is not usable (!PANGO_IS_FONT (font)), return the generic
UNKNOWN_GLYPH metrics. This is used when your backends
are misconfigured and you don't find *any* font at all.
* pango/pango-engince.c: Add unknown glyphs in fallback
shaper, instead of empty glyphs.
* pango/shape.c: Call the fall-back shaper if shaper
fails, instead of generating a dummy glyph string ourselves.
* pango/pango-layout.c (imposed_shape, shape_tab): Use
PANGO_GLYPH_EMPTY instead of glyph 0.
* pango/pango-renderer.c (pango_renderer_draw_glyph): No-op on
PANGO_GLYPH_EMPTY instead of glyph 0.
* pango/pangocairo-atsuifont.c, pango/pangocairo-win32font.c,
pango/pangocairo-fcfont.c, pango/pangocairo-font.c,
pango/pangocairo-private.h: install_font returns a boolean now.
* pango/pangocairo-render.c, pango/pangoxft-render.c: Handle font
and hex-box failures more gracefully by drawing a generic
unknown-box glyph.
* pango/pangoft2.c, pango/pangoft2-render.c: Draw the generic
unknown-box glyph here too. For unknown glyphs though, if
the font is TTF (FT_IS_SFNT), use the zero-indexed glyph,
otherwise, draw a box of proper size.
