I decided to make some changes to my api, including the name change. It's more
in step with other libs, here is the main header.
My biggest beef against the current implementation is that suppose I added
XFont support. As it is now the user would have to have both freetype and Xlib
installed for things to compile. It would be better to modularize the main
library like I had originally. What do you think?
