+/**
+ * This is meant as an base class writing
+ * easy render functions. A clean usage of multi-threading compatible
+ * with JAVA2 is implemented in GLAnimJPanel !
+ *
+ * <p>
+ *
+ * If you are interessting in further Documentation and/or
+ * the history of GL4Java follow the following link.
+ *
+ * <pre>
+ <a href="../../GL4Java.html">The GL4Java Documentation</a>
+ * </pre>
+ * <p>
+ *
+ * There are two ways of using a GLJPanel: the {@link
+ * gl4java.GLEventListener} model or the subclassing model. Earlier
+ * versions of the system only supported the subclassing model. The
+ * default implementations of {@link #init}, {@link #display},
+ * {@link #reshape} and {@link #doCleanup}
+ * now send events to GLEventListeners; they can
+ * still be overridden as before to support the subclassing model.
+ *
+ * <p>
+ * If using the subclassing model, you should override the following
+ * methods for your needs:
+ * <pre>
+ <a href="GLJPanel.html#init()">preInit - initialisation before creating GLContext</a>
+ <a href="GLJPanel.html#init()">init - 1st initialisation after creating GLContext</a>
+ <a href="GLJPanel.html#doCleanup()">doCleanup - OGL cleanup prior to context deletion</a>
+ <a href="GLJPanel.html#display()">display - render your frame</a>
+ <a href="GLJPanel.html#reshape(int, int)">reshape - to reshape (window resize), gljResize() is allready invoked !</a>
+ * </pre>
+ *
+ * To check if you can use the GLContext and GL and GLU methods,
+ * use the function
+ * <pre>
+ <a href="GLJPanel.html#cvsIsInit()">cvsIsInit</a>
+ * </pre>
+ * <p>
+ * IF you remove/release a GLJPanel,
+ * e.g. you want to close/dispose it�s Window (which contains this GLJPanel),
+ * you HAVE TO call:
+ *
+ * <pre>
+ <a href="GLJPanel.html#cvsDispose()">cvsDispose</a>
+ * </pre>
+ * You should call this before releasing/dispose this Window !
+ * Also you can overwrite this class,
+ * to dispose your own elements, e.g. a Frame etc. -
+ * but be shure that you call
+ * cvsDispose implementation call this one !
+ *
+ * <p>
+ * We do override the following Canvas methods.
+ *
+ * <pre>
+ <a href="GLJPanel.html#update(java.awt.Graphics)">update</a>
+ <a href="GLJPanel.html#paint(java.awt.Graphics)">paint</a>
