Hi Alfredo,

Well, your patch gives pretty good results already. :)
Even when this is a bit unfinished, that's what CVS is open for now  

As Tom M. proposed, a drop down menu for preferred normal map format  
would be easy to add.

I've also posted in blenderartists.org, invited that developer to come  
over to review the code and suggest further improvements.
