Is there a way to measure the length of a character string as
text() or mtext() would display it? Not in characters, but in
inches or user coordinates.

I'm displaying a hierarchical list in the left margin. I'd like
to determine the length of the labels so that I can resize the
plot so the labels don't spill over into the plot area.

Like this:
+------------------
Earth |
| |
+-Africa |
| | |
| +-Nigeria |
| |
+-Europe |
| |
+-France |
