Thank's for the help.  Before you posted this, however, I spent most of
my time today trying to figure this thing out.  I got it to work,
eventually, but I set both the .ofs to zero and it worked, even though
that is not the top left corner of the area.  But it works.

After I got it to work, I wanted to try using chrome mapping with it.
The only problem I'm having now is texturing an object for chrome
mapping.  Do you know how the texturing in the SCEE chrome demo was
done?
