Rendering uses the Splash backend. Cairo is not built, so pdftocairo is
an alias of pdftoppm, as it was in slicc 6: -png/-jpeg work, but
-svg, -pdf, -ps and -eps do not; it says so and exits 99 (use
pdftops for PostScript).
There is no fontconfig. The 14 standard PDF fonts (Helvetica, Times,
Courier, Symbol, ZapfDingbats) are the URW Type1 fonts from
gsfonts (GPL with a font
exception, see share/fonts/COPYING), found through POPPLER_FONTSDIR.
Embedded fonts render as they are, and other non-embedded fonts fall back
to the closest standard font. CJK text needs poppler-data, which is not
included.
