[Magic-dev] Font Gone Haywire

[Dean Lewis]

I haven't checked the actual terms of the license as I am funded under the
same research program that funded 3DMagic's development. However, I know
it is free for non-commercial use. The code is available here, though you
have to request a password, and they're not all the prompt responding :/

Thanks for the pointers to the various functions. I'll check them out.
txInput.c though, not txOutput.c? I know I had to hack up txOutput.c
pretty bad to get it working with stdarg instead of varargs, so I wouldn't
be surprised if that was the problem.
