+/**
+ * An interface used to wrap a GL interface.
+ * <p>Typically
+ * used for implementing debugging and tracing on top of the default
+ * GL interface. You would typically use this by creating your own class
+ * that implemented all the GL methods by delegating to another GL instance.
+ * Then you could add your own behavior before or after calling the
+ * delegate. All the GLWrapper would do was instantiate and return the
+ * wrapper GL instance:
+ * <pre class="prettyprint">
+ * class MyGLWrapper implements GLWrapper {
+ *     GL wrap(GL gl) {
+ *         return new MyGLImplementation(gl);
+ *     }
+ *     static class MyGLImplementation implements GL,GL10,GL11,... {
+ *         ...
+ *     }
+ * }
+ * </pre>
