Consider Making t3f_initialize() Enable Everything By Default

[NewCreature]

We would just make the T3F_DEFAULT setting enable everything. The user could then disable individual features by doing 'T3F_DEFAULT & ~(T3F_USE_SOUND | T3F_USE_MOUSE)'. Most of the time you wouldn't want to disable features and you could use the flags returned by t3f_initialize() to determine if a needed feature failed to initialize. You could also enable each feature you want as before. The idea is to make it simple to start using, with few hurdles to accessing all of the functionality of the framework and Allegro.
