	<code class="function">glReleaseShaderCompiler</code>
	frees resources allocated by the shader compiler.  This is a hint from the application
        that additional shader compilations are unlikely to occur, at least for some period of time,
        and that the resources consumed by the shader compiler may be released and put to better use
        elsewhere.</p><p>However, if a call to <a class="citerefentry" href="glCompileShader.xml"><span class="citerefentry"><span class="refentrytitle">glCompileShader</span></span></a>
	is made after a call to <code class="function">glReleaseShaderCompiler</code>, the shader compiler must be restored
	to service the compilation request as if <code class="function">glReleaseShaderCompiler</code> had never been called.</p></div><div class="refsect1"><a id="notes"></a><h2>Notes</h2><p>Shader compiler support is optional, and thus must be queried
