[ft] Rendering text centered vertically

[Alexander Cohen]

Hi,

I've gotten to a point where i have no problems rendering text on a  
chosen baseline. I think i have a good understanding of how freetype2  
works. I can't seem to get my head around how i could render text  
centered in a bounding box.

I can get the bounding box of a string text i need to render. It  
seems to me like i'd need to get the number of pixels between the  
bbox.yMax and the baseline of the complete string i need to render in  
order to render the text centered in a bbox that is not the bbox of  
the text i want to render.

Any help is appreciated.

thanks

Alex
