gEDA-user: where is gschem font width measure function?

[Dave N6NZ <n6nz@xxxxxxxx>]

I'm working on a gschem symbol generator(*).  I'd like to measure text 
width the same way that gschem does when calculating symbol width.  For 
a long time, I've been using a personal derivative of djboxsym -- DJ's 
code simply takes strlen() * 110 and uses that.  It's a good estimate, 
but can be fooled.

Anyway, after digging into the code for a while, I'm having a hard time 
seeing where the font information comes from and how to extract the 
width.  Pointers appreciated.

* Why? The goal is ANSI compliance.  Not *any* arbitrary ANSI symbol, 
but any symbol it produces should be ANSI compliant.
