<p>Gets a string for WebGL enum</p>
<p>Note: Several enums are the same. Without more<br>context (which function) it's impossible to always<br>give the correct enum. As it is, for matching values<br>it gives all enums. Checking the WebGL2RenderingContext<br>that means</p>
<pre class="prettyprint source"><code> 0 = ZERO | POINT | NONE | NO_ERROR
1 = ONE | LINES | SYNC_FLUSH_COMMANDS_BIT
32777 = BLEND_EQUATION_RGB | BLEND_EQUATION_RGB
36662 = COPY_READ_BUFFER | COPY_READ_BUFFER_BINDING
36663 = COPY_WRITE_BUFFER | COPY_WRITE_BUFFER_BINDING
36006 = FRAMEBUFFER_BINDING | DRAW_FRAMEBUFFER_BINDING</code></pre><p>It's also not useful for bits really unless you pass in individual bits.<br>In other words</p>
<pre class="prettyprint source"><code>const bits = gl.COLOR_BUFFER_BIT | gl.DEPTH_BUFFER_BIT;
twgl.glEnumToString(gl, bits); // not going to work</code></pre><p>Note that some enums only exist on extensions. If you<br>want them to show up you need to pass the extension at least<br>once. For example</p>
<pre class="prettyprint source"><code>const ext = gl.getExtension('WEBGL_compressed_texture_s3tc`);
if (ext) {
twgl.glEnumToString(ext, 0); // just prime the function
..later..
const internalFormat = ext.COMPRESSED_RGB_S3TC_DXT1_EXT;
console.log(twgl.glEnumToString(gl, internalFormat));</code></pre><p>Notice I didn't have to pass the extension the second time. This means<br>you can have place that generically gets an enum for texture formats for example.<br>and as long as you primed the function with the extensions</p>
<p>If you're using <code>twgl.addExtensionsToContext</code> to enable your extensions<br>then twgl will automatically get the extension's enums.</p>

<p>Note that if you want to know if the extension exists you should<br>probably call <code>gl.getExtension</code> for each extension. Alternatively<br>you can check for the existance of the functions or constants that<br>are expected to be added. For example</p>
