I agree that #1 and #3 are good. I see some usefullness in #2 too but
I'd like to propose a different approach

In the original suggestion you'd have to load the source bitmaps
first, then put them into the atlas which destroys the source to make
it a subbitmap right?

I suggest you make a function that loads from file directly into an
atlas bitmap and returns subbitmap.
Perhaps it should return NULL if there's not enough space left in atlas?
BITMAP* al_load_bitmap_into_atlas(BITMAP* atlas);

As for the al_create_atlas function, I think that's unneccesary since
it's just an al_create_bitmap with one parameter instead of two.
