<h4>Test purpose</h4>
<p>The main purpose of this demo is to check that we can create cells, groups and entitys on the fly, grab an image of their display and then remove them; then create a Picture entity to display the captured image, and a Tween object that will animate the entity and destroy itself and the entity when it completes. As part of its destruction, the Tween will generate a new smoke ring.</p>
<ul>
<li>Check that additional Cells and Groups are created and destroyed - if the smoke ring shows, but no additional Cells/Groups are listed, then things are working.</li>
<li>Check that assets, entitys and tweens are listed only while active, and are removed from the library when the associated Tween completes its cycle.</li>
<li>Check also that the generated <img> elements are removed from the DOM.</li>
<li>Check that the animation halts whenever the browser page loses focus (for whatever reason), and restarts whenever it regains focus.</li>
</ul>
