I trimmed my program to a 200x32 video bitmap that gets drawn via the
al_draw* primitives. It is then blitted to 600x400 video bitmap. That
bitmap is drawn to the backbuffer (640x480). Repeat, as fast as it can
go.

Out of desperation, I tried setting ALLEGRO_NO_PRESERVE_TEXTURE.
Manual: "This can lead to speed improvements in your program."
