<h4>Test purpose</h4>
<ul>
<li>Create a Bezier entity along which the Emitter can generate particles, together with user-controlled Wheel entitys to shape the curve.</li>
<li>Create a particle world object, a Star entity, and a particle Emitter entity using them.</li>
<li>Check that the Emitter entity generates particles along the entire length of the Bezier curve.</li>
<li>Create additional, non-user-interactive shape-based entitys (Line, Oval); clone the Emitter entity (and its artefact), assigning each to the new entitys.</li>
<li>Check that the cloned Emitter entity generate particles along the entire length of the Line and Oval paths.</li>
</ul>
<p><b>Touch test:</b> should work as expected. Known issue: moving the pins is inconsistent (because pins are too small on device screens?)</p>
