+ * Tracks as closely as possible the sizes of allocated OpenGL buffer
+ * objects. When glMapBuffer or glMapBufferARB is called, in order to
+ * turn the resulting base address into a java.nio.ByteBuffer, we need
+ * to know the size in bytes of the allocated OpenGL buffer object.
+ * Previously we would compute this size by using
+ * glGetBufferParameterivARB with a pname of GL_BUFFER_SIZE, but
+ * it appears doing so each time glMapBuffer is called is too costly
+ * on at least Apple's new multithreaded OpenGL implementation. <P>
+ *
+ * Instead we now try to track the sizes of allocated buffer objects.
+ * We watch calls to glBindBuffer to see which buffer is bound to
+ * which target and to glBufferData to see how large the buffer's
+ * allocated size is. When glMapBuffer is called, we consult our table
+ * of buffer sizes to see if we can return an answer without a glGet
+ * call. <P>
+ *
+ * We share the GLBufferSizeTracker objects among all GLContexts for
+ * which sharing is enabled, because the namespace for buffer objects
+ * is the same for these contexts. <P>
+ *
+ * Tracking the state of which buffer objects are bound is done in the
+ * GLBufferStateTracker and is not completely trivial. In the face of
+ * calls to glPushClientAttrib / glPopClientAttrib we currently punt
+ * and re-fetch the bound buffer object for the state in question;
+ * see, for example, glVertexPointer and the calls down to
+ * GLBufferStateTracker.getBoundBufferObject(). Note that we currently
+ * ignore new binding targets such as GL_TRANSFORM_FEEDBACK_BUFFER_NV;
+ * the fact that new binding targets may be added in the future makes
+ * it impossible to cache state for these new targets. <P>
+ *
+ * Ignoring new binding targets, the primary situation in which we may
+ * not be able to return a cached answer is in the case of an error,
+ * where glBindBuffer may not have been called before trying to call
+ * glBufferData. Also, if external native code modifies a buffer
+ * object, we may return an incorrect answer. (FIXME: this case
+ * requires more thought, and perhaps stochastic and
+ * exponential-fallback checking. However, note that it can only occur
+ * in the face of external native code which requires that the
+ * application be signed anyway, so there is no security risk in this
+ * area.)

+ * Tracks as closely as possible which OpenGL buffer object is bound

+ * GLBufferStateTracker objects are allocated on a per-OpenGL-context basis.
+ * This class is used to verify that e.g. the vertex
+ * buffer object extension is in use when the glVertexPointer variant
+ * taking a long as argument is called. <P>
+ *
+ * Note that because the enumerated value used for the binding of a
+ * buffer object (e.g. GL_ARRAY_BUFFER) is different than that used to
+ * query the binding using glGetIntegerv (e.g.
+ * GL_ARRAY_BUFFER_BINDING), then in the face of new binding targets
+ * being added to the GL (e.g. GL_TRANSFORM_FEEDBACK_BUFFER_NV) it is
+ * impossible to set up a query of the buffer object currently bound
+ * to a particular state. It turns out that for some uses, such as
+ * finding the size of the currently bound buffer, this doesn't
+ * matter, though of course without knowing the buffer object we can't
+ * re-associate the queried size with the buffer object ID. <P>
+ *
+ * Because the namespace of buffer objects is the unsigned integers
+ * with 0 reserved by the GL, and because we have to be able to return
+ * both 0 and other integers as valid answers from
+ * getBoundBufferObject(), we need a second query, which is to ask
+ * whether we know the state of the binding for a given target. For
+ * "unknown" targets such as GL_TRANSFORM_FEEDBACK_BUFFER_NV we return
+ * false from this, but we also clear the valid bit and later refresh
+ * the binding state if glPushClientAttrib / glPopClientAttrib are
+ * called, since we don't want the complexity of tracking stacks of

+ * 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

+ * to keep them separated (the combined region would not be monotone).
+ * - in any case, we must leave some record of vEvent in the dictionary,

+ *
+ * Tessellation consists of adding interior edges (actually pairs of

+ * The basic idea is explained in Preparata and Shamos (which I don''t
+ * have handy right now), although their implementation is more
+ * complicated than this one. The are two edge chains, an upper chain
+ * and a lower chain. We process all vertices from both chains in order,
+ * from right to left.
+ *
+ * The algorithm ensures that the following invariant holds after each
+ * vertex is processed: the untessellated region consists of two
+ * chains, where one chain (say the upper) is a single edge, and
+ * the other chain is concave. The left vertex of the single edge
+ * is always to the left of all vertices in the concave chain.
+ *
+ * Each step consists of adding the rightmost unprocessed vertex to one
+ * of the two chains, and forming a fan of triangles from the rightmost
+ * of two chain endpoints. Determining whether we can add each triangle
+ * to the fan is a simple orientation test. By making the fan as large

+ // to represent the contexts for e.g. the Java2D back buffer. When
+ // the Java2D/JOGL bridge is active, this means that if we want to
+ // be able to share textures and display lists with the Java2D
+ // contexts, we need to use the CGL APIs rather than the NSOpenGL
+ // APIs on the JOGL side. For example, if we create a pbuffer using
+ // the NSOpenGL APIs and want to share textures and display lists
+ // between it and the Java2D back buffer, there is no way to do so,
+ // because the Java2D context is actually a CGLContextObj and the
+ // NSOpenGLContext's initWithFormat:shareContext: only accepts an
+ // NSOpenGLContext as its second argument. Of course there is no way
+ // to wrap an NSOpenGLContext around an arbitrary CGLContextObj.
+ //
+ // The situation we care most about is allowing a GLPbuffer to share
+ // textures, etc. with a GLJPanel when the Java2D/JOGL bridge is
+ // active; several of the demos rely on this functionality. We aim
+ // to get there by allowing a GLPBuffer to switch its implementation
+ // between using an NSOpenGLPixelBuffer and a CGLPBufferObj. In
+ // order to track whether this has been done we need to have the
+ // notion of a "mode" of both the MacOSXCGLDrawable and the
+ // MacOSXGLContext. Initially the mode is "unspecified", meaning it
+ // leans toward the default (NSOpenGL). If sharing is requested
+ // between either a GLJPanel and a GLPbuffer or a GLCanvas and a
+ // GLPbuffer, the GLPbuffer will be switched into the appropriate
+ // mode: CGL mode for a GLJPanel and NSOpenGL mode for a GLCanvas.
+ // To avoid thrashing we support exactly one such switch during the
+ // lifetime of a given GLPbuffer. This is not a fully general
+ // solution (for example, you can't share textures among a
+ // GLPbuffer, a GLJPanel and a GLCanvas simultaneously) but should
