If the bounding box is "wrong" in the file, the connection gets messed
up anyway the first time someone clicks on the UML Cass.

Agreed. But really: I don't think there is a reliable way of computing
text extends without depending on the actual resolution. There is a lot
of effort in fonts to accomodate different resolutions. And as far as I
know, fonts are always bound to specific resolutions and can change
their extents quite unexpectedly when switching to the next
bigger/smaller font size. Hopefully I'm a bit pessimistic here...

Maybe we could simply ask the Pango people about that? They should be
very competent in font issues.
