Doing that causes some ugly artifacts, especially when there is a flickering light right next to an opaque cell:</p>
<p>frame 1, origin at the centre of 'f'<br />
.....<br />
.....<br />
....<br />
...f#<br />
....#<br />
....#<br />
...#</p>
<p>frame 2, origin one tile north of 'f'<br />
.....<br />
.......<br />
.......<br />
.......<br />
...f###<br />
....#<br />
...#</p>
<p>When the animation flicks quickly between these two frames (and the effect is even more noticeable with a larger radius), a rather jarring effect is produced.</p>
<p>If you could specify the origin of the light with sub-tile granularity, this problem could be avoided.</p></div>
