Cufon font SwitzerlandCondensed: bold is shifted up compared to normal

[sgervais71]

I am not quite sure I am at the right place to mention this bug.
But if you look at this page you should see what I am talking about.

As you will see the strong text is shifted up of about 1 pixel.
I mentioned it to the theme author, but they assure me that it is not their fault this bug is the the cufon itself.
