Yes, just did. In the memory case, it uses
allegro_gl_screen_blit_from_memory, and then blits using glDrawPixels,
in the video case, it uses allegro_gl_screen_blit_to_self, and then
blits using glBegin(GL_QUADS);

Which looks right to me..

But something actually is fishy, because it doesn't blit to (0/0), but
somewhere in the middle of the screen - and a white rectangle appears
during the second test. Maybe the example misses
allegro_set_projection() or something?
