[Freetype] Same font face, many sizes - how to ?

[Alexey Kryshen on mail.ru]

Hi, freetype.

    I need render many strings with same font face but different
character sizes. What to do better:

1) Have one FT_Face and use many FT_Size (FT_Activate_Size)
or
2) Have many (per size) FT_Face each with own size ?

I prefer have many FT_Face objects with different sizes rather than
have deal with FT_Activate_Size(). But I can't find in docs how cheap to
have many FT_Face objects with same face but different sizes ?

So my question: can I have per-size FT_Face objects without any
significant memory usage issues ?

More detailed: about 6th sizes per face and about 5 faces at same
time I use in my application. Totally about 30th FT_Face objects.
