First off I just wanted to say how awesome Allegro 5 is. I know it's been out for a while, but I've only now had a chance to check it out and it's really great!
I was just wondering, I noticed that there was a _al_create_memory_bitmap function in bitmap.c, but it currently is private. Is there any specific reason why this method isn't exposed? It seems like it would be a convenient method to have every once in a while. In my case, it was exactly what I was looking for (I only wanted to create one memory bitmap so it seemed silly to change the flags.) Of course, it was easy for me to expose the method, but I'm guessing that if I wanted it it's likely that other people would as well.
Anyways, just wanted to mention it.
