FT_OUTLINE_EVEN_ODD_FILL is never set by freeetype. So actually
FreeType always uses non-zero winding rule even for TrueType. More so,
the outer outline is always filled on the inside regardless of the
direction (ftgrays.c:1285). FreeType is less sophisticated and resort
to what works the best even for broken fonts.
