   8             <code class="function">glGenTextures</code> returns <em class="parameter"><code>n</code></em> texture names in <em class="parameter"><code>textures</code></em>.
   9             There is no guarantee that the names form a contiguous set of integers;
  10             however, it is guaranteed that none of the returned names was in use
  11             immediately before the call to <code class="function">glGenTextures</code>.
  12         </p><p>
  13             The generated textures have no dimensionality; they assume the dimensionality
  14             of the texture target to which they are first bound
  15             (see <a class="citerefentry" href="glBindTexture.xml"><span class="citerefentry"><span class="refentrytitle">glBindTexture</span></span></a>).
  16         </p><p>
  17             Texture names returned by a call to <code class="function">glGenTextures</code> are not returned by
  18             subsequent calls, unless they are first deleted with
