I see you have put the whole updating mechanism into a black box. I
understand the rationale (and it would probably make the life easier for the
Windows port for example), but isn't that a little too high-level ? Why not
simply query the number of video pages with al_create_display() and expose
them through a display->page[] array ?

Nice idea. I'm strongly for giving as much power as possible to the user, by
exposing as many low-level interfaces as possible.

Yes. I have a direct DirectX (!) windowed driver somewhere on my hard drive
for about one year, but it can't currently be merged into Allegro.
