Thanks José, I am been able to enter native text on Mac and I really  
appreciate it. So now I see that it at least usable on Mac. And that  
really makes changes...

Now I'm expiriencing minor (?) bug with it. It complies when entering  
text.randomly somewhere in GrafPort#copyBitsColor... and  
FreeTypeFont#displayLineGlyphOn: with "primitive has failed". May be  
problem with FreeType. Did you meet a similar problem?

So if it works I don't know why it's not yet the part of squeak. Is it  
a quick fix?
