The mode is selectable with:

	cairo_font_options_set_antialias (font_options,
					  CAIRO_ANTIALIAS_SUBPIXEL);

But poppler really shouldn't need to be calling this
explicitly. Instead, cairo should be setting the font options
automatically so that when cairo renders to an X surface, the subpixel
settings are enabled by default if the user has configured his system
to do so, (such as with GNOME or KDE font-rendering preferences).

Tobias, what kind of surface are you rendering to? And do you have
your system font settings set to do sub-pixel rendering?
