branch: master
commit cb9e7b7aacab1da319b1224cee4844ab11d1c26f

    [truetype] Avoid some memory zeroing in variations.
    
    * src/truetype/ttgxvar.c (ft_var_readpackeddeltas, ft_var_load_avar,
    ft_var_load_item_variation_store, ft_var_load_gvar): Use FT_QNEW_ARRAY
    if memory immediately initialized or discarded otherwise.
