ding! ding!   The final piece falls into place, and I now "see".  :)
I can even imagine what all the user font stuff is probably doing
behind the scenes (eg: start font; custom path hook; end font),
and thus why it exists.

Behdad, my deepest thanks for all your patient help (Even when you
weren't sure where I was going)!  I think I've got many/most of the
pieces I need to implement most/all of our text features.  If you're
ever in eastern Canada, I owe you a drink!

Thanks also to the all the Cairo developers, for their great product!
Ian
