Ion bindings for SDL_ttf functions
Copy the 'sdl_ttf' folder to your $IONHOME/system_packages
directory or add it to your $IONPATH
Then in your .ion file:
import sdl_ttf { ... };
...
font := TTF_OpenFont(font_path, font_size);
These bindings have a dependency on the sdl
package, which is currently in Ion's system_packages dir by default.
