<p class="description">
Destroys the WebGL resources held by this object. Destroying an object allows for deterministic
release of WebGL resources, instead of relying on the garbage collector to destroy this object.
<br /><br />
Once an object is destroyed, it should not be used; calling any function other than
<code>isDestroyed</code> will result in a <a href="DeveloperError.html">DeveloperError</a> exception. Therefore,
assign the return value (<code>undefined</code>) to the object as done in the example.

<h5>Throws:</h5>
<div class="param-desc">
<span class="param-type"><a href="DeveloperError.html">DeveloperError</a></span>
