            <code class="function">glValidateProgramPipeline</code> instructs the implementation to validate the
            shader executables contained in <em class="parameter"><code>pipeline</code></em> against the current GL state.
            The implementation may use this as an opportunity to perform any internal shader modifications
            that may be required to ensure correct operation of the installed shaders given the
            current GL state.
        </p><p>
            After a program pipeline has been validated, its validation status is set to <code class="constant">GL_TRUE</code>.
            The validation status of a program pipeline object may be queried by calling
            <a href="glGetProgramPipeline.xml"><span class="citerefentry"><span class="refentrytitle">glGetProgramPipeline</span></span></a> with
            parameter <code class="constant">GL_VALIDATE_STATUS</code>.
        </p><p>
            If <em class="parameter"><code>pipeline</code></em> is a name previously returned from a call to
            <a href="glGenProgramPipelines.xml"><span class="citerefentry"><span class="refentrytitle">glGenProgramPipelines</span></span></a> but
            that has not yet been bound by a call to <a href="glBindProgramPipeline.xml"><span class="citerefentry"><span class="refentrytitle">glBindProgramPipeline</span></span></a>,
            a new program pipeline object is created with name <em class="parameter"><code>pipeline</code></em> and
            the default state vector.
