<h4>Test purpose</h4>
<ul>
<li>Setup a conic gradient, and a block entity which uses the gradient for its fillStyle value</li>
<li>Check that we can successfully manipulate the gradient's start and end coordinates, and its start angle</li>
<li>Check that we can successfully manipulate the palettes's start and end cursors</li>
<li>Check that we can dynamically add and remove color stops</li>
</ul>
<p><b>Known issue</b> - For browsers that do not support conic gradients in the canvas this gradient will return a solid, transparent color for fill and stroke styles using it.</p>
<p><b>Touch test:</b> not required</p>
