/** 
 * Tracks the creation of server-side OpenGL objects which can be
 * shared between contexts. Ordinarily, when an OpenGL context is
 * deleted and no other contexts are sharing server-side objects with
 * it, all of the server-side objects are automatically deleted by the
 * OpenGL implementation. It is not necessary for the end user to
 * explicitly delete these objects. However, when the Java2D/OpenGL
 * pipeline is active and frame buffer objects are being used for
 * rendering, it is necessary for all OpenGL contexts created by JOGL
 * to share server-side objects with the Java2D OpenGL context. This
 * means that these objects "leak" into the namespace used by Java2D.
 * In order to prevent memory leaks and to present the same
 * programming model to the end user, it is necessary to track the
 * creation and destruction of all of these server-side OpenGL objects
 * and to explicitly release them when all of the JOGL-created
 * contexts which can see them have been released. <P>
 *
 * The {@link #ref ref} and {@link #unref unref} methods should be
 * used during the creation and destruction of OpenGL contexts by JOGL
 * in order to update the liveness of the objects being tracked. The
 * various other methods should be called by the OpenGL binding in the
 * various named methods.
