   6             <code class="function">glCallList</code> causes the named display list to be executed.
   7             The commands saved in the display list are executed in order,
   8             just as if they were called without using a display list.
   9             If <em class="parameter"><code>list</code></em> has not been defined as a display list,
  10             <code class="function">glCallList</code> is ignored.
  11         </p><p>
  12             <code class="function">glCallList</code> can appear inside a display list.
  13             To avoid the possibility of infinite recursion resulting from display lists
  14             calling one another,
  15             a limit is placed on the nesting level of display
  16             lists during display-list execution.
  17             This limit is at least 64, and it depends on the implementation.
  18         </p><p>
  19             GL state is not saved and restored across a call to <code class="function">glCallList</code>.
  20             Thus,
  21             changes made to GL state during the execution of a display list
  22             remain after execution of the display list is completed.
