<p>I&rsquo;d like to emphasize that algorithmically and conceptually, there is <i>no</i> difference between scanning out a polygon top to bottom and scanning it out left to right; it is only in conjunction with the hardware organization of Mode X that the scanning direction matters in the least.</p>

<p>Actually, we also advanced the source pointer by the Y integer amount back when we added BP to SI; all that&rsquo;s left is to detect whether our addition to the Y fractional current coordinate produced a carry. That&rsquo;s easily done by testing bit 15 of EDX; if it&rsquo;s zero, there was no carry and we&rsquo;re done; otherwise, Y carried, so we have to reset bit 15 and advance the source pointer by one scanline. The resulting program flow is shown in Figure 58.7. Note that unlike the X fractional addition, we can&rsquo;t get away with just adding in the carry from the Y fractional addition, because when the Y fraction carries, it indicates a move not from one pixel to the next on a scanline (a single byte), but rather from one scanline to the next (a full scanline width).</p>
