I think the easiest way to do this is to use Ghostview to "convert to
EPS", and have it recalculate the bounding box as it does so.  Since
it's working with a Postscript interpreter, it does the bounding box
calculation very accurately; playing around with margins is likely to
lead to inconsistencies depending on labels, etc.
