Hi Diego,

Thanks!
Here's some comments:

Can't you just copy all utf/locale to the blenfont module? It goes  
there later anyway I guess.

Not to nitpick, this looks very intuitive and usable... :) but given  
the naming conventions for WM/UI code (first subject, then  
verb/operation), you could also simplify it:

BLF_font()		/* sets font */
BLF_draw()		/* draws string (what else :) */
BLF_position()
BLF_scale()
BLF_boundbox()

/* the optional getters */
BLF_position_get()
BLF_scale_get()
BLF_boundbox_get()

And add a:

BLF_rotation(float degrees) :)

... now this makes me wonder how to cope with all the weird 2d view  
matrices in Blender. We had to solve it with giving "aspect" to the  
font code, so it knows how big a stride is. Is 'scale' and 'boundbox'  
then in what view space? You might consider to do it all automatic for  
us dumb Blender coders, with a:

BLF_windowmatrix() /* sets 4x4 2d matrix transform to use for drawing */

All drawing (positions, scale, boundbox, etc) then gets wrapped using  
this matrix.
