ps backend, when usetex=True, uses latex with psfrag package to
generate the output (with some extra steps).
It seems that the bounding box information is not correctly recovered
during this process.
I first thought that it would be quite difficult to get this correct,
however the attached (relatively simple) patch seems to work fine.
Ken, can you try the patch and see if it works?
