        <p>Generic attribute locations may be specified in the shader source
    text using a <code class="function">location</code> layout qualifier. In this case,
    the location of the attribute specified in the shader's source takes precedence
    and may be queried by calling <a class="citerefentry" href="glGetAttribLocation"><span class="citerefentry"><span class="refentrytitle">glGetAttribLocation</span></span></a>.
