Also, a very graphics intensive FPS (If one were ever made with Allegro, and I don't rule that possibility out) might run slow at native resolution, for example.

Wouldn't it work if you essentially do this when toggling the fullscreen
flag under Windows:

al_destroy_display(display)
display = al_create_display(new_width, new_height)

With the (existing?) code to re-upload all bitmaps of course. Things
like user-created FBOs and VBOs and shaders would need to be destroyed
first and then re-created by the user.
