I think both sound good, but at least the second would make things a lot 
better already. I'd start with the second one.

Yeah, I kind of like the display option idea. I suggest that it 
overrides al_set_new_display_adapter. If possible, it'd be nice to move 
it, but if not, I think just being able to select it for the next full 
screen transition would be good.
