Tip: Measuring string widths is fairly expensive. (It's basically like drawing the string, minus the actual rendering of the pixels.) If you can, cache the result instead of calling it frequently.

Also, keep in mind that character shapes may stick out of either edge by a few pixels, especially with italics or script fonts. It's usually safest to pad your bounding box by some fraction of the point-size.
