    Small const correctness fix
    
    clang complains that initializing 'FcPattern *' (aka 'struct _FcPattern *')
    with an expression of type 'const FcPattern *' (aka 'const struct _FcPattern *')
    discards qualifiers [-Wincompatible-pointer-types-discards-qualifiers]
          FcPattern *pattern = pango_fc_font_key_get_pattern (key);
