<h3>How to place several instances of the editor on a single webpage</h3>

<p>You can place several editors on a signle webpage. In that case each <a href="placing.htm#DrawCanvas">DrawCanvas</a>
must have the parameter <i>instance</i>. The parameter's value can be any string, but it must be UNIQUE for each canvas
on the page.</p>

For example:
<pre>
 for one canvas
    &lt;param name="instance" value="A"&gt;
 for another canvas
    &lt;param name="instance" value="B"&gt;
</pre>

<p>Each control panel (such as <a href="placing.htm#Tool">ToolPanel</a>, <a href="placing.htm#Color">ColorPanel</a>, etc..)
must also have the parameter <i>instance</i>, and it's value must be the same that the canvas instance the panel serves for.
</p>
