I mean that a line that is half the width of the screen takes longer, because it has 1) more pixels, and 2) each pixel has more bits. If we are looking at vectors, then the time for a constant speed processor to draw them goes up as the square root of the frame buffer size. (Of course, the time to fill an area goes up directly with frame buffer size.) -michael Music synthesis for 8-bit Apple II's!
