wb-scene 1.0: a synthetic game (no game data) drawn by the kit's scene module on the kit's clock: the window's clean picture, the map for the margins, objects with an identity (one of them blinking), a hardware sprite, HUD rows; arrows move the camera, ?soft=1 soft clamp, ?smooth=1 vertical smoothing, ?pair=2 pairing with older frames, ?gl=0 the 2D path (the CPU reference), ?s=N device pixels per game pixel.
