Description
The afont OpenGL code has some minor coordinate issues and issues printing against transparency, as well as requiring the fonts be converted by an external utility. Jared Minch, the original writer of afont, is out of contact, and NeHe? has a great tutorial about using freetype2 (very famous/good font loading library) with SDL/OpenGL.

Got in contact with Jared and received an updated version of afont that nullifies these concerns.

I won't be able to do any UI work or use Epiar in general without an option besides afont. My graphics card doesn't handle the way afont renders text.

Adapted Maoserr's FreeType? work to add optional freetype support with a configure flag "--enable-freetype". This is off by default so systems without freetype will use AFont (for now).
I wasn't able to use Maoserr's FreeType? implementation because (1) it removed afont and (2) it required warping all the screen coordinates to get the text to draw rightside-up. I fixed the mirrored text by doing an opengl translation (pushmatrix/flip/popmatrix) as a wrapper for each text Render.
FreeType? does not support the .af format (AFONT specific?), so all fonts are rendered with FreeSans?.ttf until we find replacements for the opther fonts.
This solves my problems (Full game speed even with text on the screen), and should not affect other developers or users.
