The bitmap font is embedded in your the PDF. The reason you can't see it
is that the bitmap glyphs have a y coordinate of -78338. I have
reproduced this problem using the mixed.pango from
http://lists.freedesktop.org/archives/cairo/2007-February/009476.html
when I don't have any Chinese TrueType fonts installed. I have confirmed
that Pango is passing in the invalid y coordinate to cairo_show_glyphs()
when using the PDF or PS surface.
