I have fixed it. Or, I have a better handle on what the stupid thing is
doing. LOL.
The problem was a couple of things.
1. Michael was right. There was no file named Helvetica.ttf installed
on my machine.
2. The path were I thought MPL was looking for files wasn't the right
path. I thought it was looking in the mpl-data/fonts/ttf directory...
Which it does. But it ALSO looks in system's font directories. So I was
finding fonts that weren't in the mpl-data directory. This was very
confusing.
3. I was generally angry at it.
Now, if you want to change the font, just look in the system's font
directory, pick the one you want, and then change the font.family name.
It will change everything else. Easy as pie.
