<p>The point coordinates sent to the emitters are the transformed version of the original coordinates (this is important for high accuracy during scan-conversion). The transformation is simple:</p>
<pre class="colored">
  x' = (x &lt;&lt; shift) - delta                                        
  y' = (x &lt;&lt; shift) - delta
