-/** Singleton thread upon which all OpenGL work is performed by
-    default. Unfortunately many vendors' OpenGL drivers are not really
-    thread-safe and stability is much improved by performing OpenGL
-    work on at most one thread. This is the default behavior of the
-    GLAutoDrawable implementations according to the {@link
-    javax.media.opengl.Threading Threading} class. The GLWorkerThread
-    replaces the original AWT event queue thread-based mechanism for
-    two reasons: first, more than one AWT event queue thread may be
-    spawned, for example if a dialog is being shown; second, it avoids
-    blocking the AWT event queue thread during OpenGL rendering. */
