Thanks for the updated link.
From there, if I located the correct bit of code, I found:
CGAffineTransformMake(1, 0, -tanf(SYNTHETIC_OBLIQUE_ANGLE * acosf(0) / 90),
1, 0, 0));
where SYNTHETIC_OBLIQUE_ANGLE = 14.
My matrix math is a bit rusty...how would I turn that into a series of method
calls to NSAffineTransform?

I agree. I would much rather use a real italic, but, as you pointed out, I need
to be certain that the font does exist. Of course, I could put in a lot of code
to take all of the different failure cases into account...an option.
