This is not true.  stringwidth returns the change in current
point after a show of the specified string.  For Roman
typefaces, only the x component is non-zero.  The y component
is zero because the baseline doesn't change (as it might in a
Japanese font).  Actually, the resulting width is NOT the
bounding box; it must be adjusted by the side bearings of the
first and last characters. This is only a problem, however, if
you need a pretty close fit around the string.
 
If metric info is not available in the font dictionary, you can
use "charpath flattenpath pathbbox", but I think the resulting
bounding box is relative to device coordinates, so you want to
do the pathbbox in a coordinate system that is aligned to
device space (ie. not rotated or skewed).
