That's essentially what you need to do but I think in a slightly different
order.

using:
http://www.php.net/manual/en/function.imagettfbbox.php

you could write a small loop to keep adjusting the break in the text until
the bounding box is just small enough to fit inside the image.

By the way, that font looks great at 7.9 -- real sharp and easy to read.
