Re: [ft] putting text in a box

[Dave Calkins]

Thanks a ton for the help!  Sure enough, my code was considering the 
overall size from the bbox (upper right - lower left) but I hadn't 
considered the fact that a negative lower left point was exactly the 
information I needed :)  Live and learn!

I'm able to now subtract the lower left x and y from my pen position and 
the result is the text itself is "flush" against the desired position.
