+/** A higher-level abstraction than {@link GLDrawable} which supplies
+    an event based mechanism ({@link GLEventListener}) for performing
+    OpenGL rendering. A GLAutoDrawable automatically creates a primary
+    rendering context which is associated with the GLAutoDrawable for
+    the lifetime of the object. This context has the {@link
+    GLContext#setSynchronized synchronized} property enabled so that
+    calls to {@link GLContext#makeCurrent makeCurrent} will block if
+    the context is current on another thread. This allows the internal
+    GLContext for the GLAutoDrawable to be used both by the event
+    based rendering mechanism as well by end users directly. */
