+/**
+ * Adds capabilities to set a shared {@link GLContext} directly or via an {@link GLAutoDrawable}.
+ * <p>
+ * Sharing of server-side OpenGL objects such as buffer objects, e.g. VBOs,
+ * and textures among OpenGL contexts is supported with this interface.
+ * </p>
+ * <p>
+ * A <i>master</i> {@link GLContext} is the {@link GLContext} which is created first.
+ * Subsequent shared {@link GLContext} w/ the <i>master</i> are referred as <i>slave</i> {@link GLContext}.
+ * </p>
+ * <p>
+ * Implementations of this interface control the <i>slave's</i> {@link GLContext} and {@link GLAutoDrawable} realization,
+ * i.e. the <i>slave</i> {@link GLAutoDrawable} will not be realized before their associated <i>master</i>.
+ * </p>
+ * <p>
+ * Using the nearest or same {@link GLCapabilitiesImmutable#getVisualID(javax.media.nativewindow.VisualIDHolder.VIDType) visual ID}
+ * or {@link GLCapabilitiesImmutable caps} across the shared {@link GLDrawable}s will yield best compatibility.
+ * </p>
+ * <h5><a name="lifecycle">Lifecycle Considerations</a></h5>
+ * <p>
+ * After shared objects are created on the <i>master</i>, the OpenGL pipeline
+ * might need to be synchronized w/ the <i>slaves</i>, e.g. via {@link GL#glFinish()}.
+ * At least this has been experienced w/ OSX 10.9.
+ * </p>
+ * <p>
+ * In general, destroying a <i>master</i> {@link GLContext} before their shared <i>slaves</i>
+ * shall be permissible, i.e. the OpenGL driver needs to handle pending destruction of shared resources.
+ * This is confirmed to work properly on most platform/driver combinations,
+ * see unit test <code>com.jogamp.opengl.test.junit.jogl.acore.TestSharedContextVBOES2NEWT3</code> and similar.
+ * </p>
+ * <p>
+ * However, to avoid scenarios with buggy drivers, users <i>may not</i> destroy the
+ * <i>master</i> {@link GLContext} before its shared <i>slave</i> {@link GLContext} instances
+ * <i>as long as they are using them</i>.<br>
+ * Otherwise the OpenGL driver may crash w/ SIGSEGV, due to using already destroyed shared resources,
+ * if not handling the pending destruction of the latter!<br>
+ * Either proper lifecycle synchronization is implemented, e.g. by notifying the <i>slaves</i> about the loss of the shared resources,
+ * <i>or</i> the <i>slaves</i> validate whether the resources are still valid.
+ * </p>
+ * <p>
+ * To simplify above lifecycle issues, one may use a {@link GLDrawableFactory#createDummyDrawable(javax.media.nativewindow.AbstractGraphicsDevice, boolean, GLCapabilitiesImmutable, GLCapabilitiesChooser) dummy}
+ * {@link GLDrawable} and it's {@link GLContext} as the <i>master</i> of all shared <i>slave</i> {@link GLContext}.
+ * Since this <i>dummy instance</i> does not depend on any native windowing system, it can be controlled easily w/o being <i>in sight</i>.<br>
+ * Below code creates a {@link GLAutoDrawable} based on a <i>dummy GLDrawable</i>:
+ * <pre>
+        // GLProfile and GLCapabilities should be equal across all shared GL drawable/context.
+        final GLCapabilitiesImmutable caps = ... ;
+        final GLProfile glp = caps.getGLProfile();
+        ..
+        final boolean createNewDevice = true; // use 'own' display device!
+        final GLAutoDrawable sharedDrawable = GLDrawableFactory.getFactory(glp).createDummyAutoDrawable(null, createNewDevice, caps, null);
+        sharedDrawable.display(); // triggers GLContext object creation and native realization.
+        ...
+        // Later a shared 'slave' can be created e.g.:
+        GLWindow glad = GLWindow.create(caps); // or any other GLAutoDrawable supporting GLSharedContextSetter
+        glad.setSharedAutoDrawable(sharedDrawable);
+        glad.addGLEventListener(..);
+        glad.setVisible(true); // GLWindow creation ..
+ * </pre>
+ * </p>
+ * <h5><a name="synchronization">GL Object Synchronization</a></h5>
+ * <p>
+ * Usually synchronization of shared GL objects should not be required, if the shared GL objects
+ * are created and immutable before concurrent usage.
+ * </p>
+ * <p>
+ * However, using drivers exposing {@link GLRendererQuirks#NeedSharedObjectSync} always
+ * require the user to synchronize access of shared GL objects.
+ * </p>
+ * <p>
+ * Synchronization can be avoided if accessing the shared GL objects
+ * exclusively via a queue or {@link com.jogamp.common.util.Ringbuffer Ringbuffer}, see GLMediaPlayerImpl as an example.
+ * </p>
+ * </p>

-    Note that because this component attempts to use pbuffers for
-    rendering, and because pbuffers can not be resized, somewhat
-    surprising behavior may occur during resize operations; the {@link
-    GLEventListener#init} method may be called multiple times as the
-    pbuffer is resized to be able to cover the size of the GLJPanel.
-    This behavior is correct, as the textures and display lists for
-    the GLJPanel will have been lost during the resize operation. The
-    application should attempt to make its GLEventListener.init()
-    methods as side-effect-free as possible. </P>

+ * Tracking of {@link GLBufferStorage} instances via GL API callbacks.
+ * <p>
+ * See {@link GLBufferStorage} for generic details.

+ * <p>
+ * Buffer storage is created via
+ * <ul>
+ *   <li><code>glBufferStorage</code> - storage creation with target via {@link #createBufferStorage(GLBufferStateTracker, GL, int, long, Buffer, int, int, CreateStorageDispatch, long)}</li>
+ *   <li>{@link GL#glBufferData(int, long, java.nio.Buffer, int)} - storage recreation with target via {@link #createBufferStorage(GLBufferStateTracker, GL, int, long, Buffer, int, int, CreateStorageDispatch, long)}</li>
+ *   <li>{@link GL2#glNamedBufferDataEXT(int, long, java.nio.Buffer, int)} - storage recreation, direct, via {@link #createBufferStorage(GL, int, long, Buffer, int, CreateStorageDispatch, long)}</li>
+ * </ul>
+ * Note that storage <i>recreation</i> as mentioned above also invalidate a previous storage instance,
+ * i.e. disposed the buffer's current storage if exist and attaches a new storage instance.
+ * </p>
+ * <p>
+ * Buffers storage is disposed via
+ * <ul>
+ *   <li>{@link GL#glDeleteBuffers(int, IntBuffer)} - explicit, direct, via {@link #notifyBuffersDeleted(int, IntBuffer)} or {@link #notifyBuffersDeleted(int, int[], int)}</li>
+ *   <li>{@link GL#glBufferData(int, long, java.nio.Buffer, int)} - storage recreation via target</li>
+ *   <li>{@link GL2#glNamedBufferDataEXT(int, long, java.nio.Buffer, int)} - storage recreation, direct</li>
+ * </ul>
+ * </p>
+ *
+ * <p>
+ * Implementation throws a {@link GLException} in all <i>construction</i> methods as listed below,
+ * if GL-function constraints are not met. <code>createBufferStorage</code> also throws an exception
+ * if the native GL-function fails.
+ * <ul>
+ *   <li>{@link #createBufferStorage(GLBufferStateTracker, GL, int, long, Buffer, int, int, CreateStorageDispatch, long)}, etc ..</li>
+ *   <li>{@link #mapBuffer(GLBufferStateTracker, GL, int, int, MapBufferAllDispatch, long)}, etc ..</li>
+ * </ul>
+ * In <i>destruction</i> and informal methods, i.e. all others, implementation only issues a WARNING debug message, if enabled.
+ * </p>
+ *
+ * <p>
+ * Buffer mapping methods like {@link GL#mapBuffer(int, int)} ...,
+ * require knowledge of the buffer's storage size as determined via it's creation with
+ * {@link GL#glBufferData(int, long, java.nio.Buffer, int)} ....
+ * </p>
+ * <p>
+ * Hence we track the OpenGL buffer's {@link GLBufferStorage} to be able to
+ * access the buffer's storage size. The tracked {@link GLBufferStorage} instances
+ * also allow users to conveniently access details of their created and maybe mapped buffer storage.
+ * </p>
+ * <p>
+ * The {@link GLBufferObjectTracker} and it's tracked {@link GLBufferStorage} instances
+ * maybe shared across multiple OpenGL context, hence this class is thread safe and employs synchronization.
+ * </p>
+ * <p>
+ * Implementation requires and utilizes a local {@link GLBufferStateTracker}
+ * to resolve the actual buffer-name bound to the given target.
+ * </p>
+ * <p>
+ * Note: This tracker requires to be notified about all OpenGL buffer storage operations,
+ * as well as the local {@link GLBufferStateTracker} to be notified about all
+ * OpenGL buffer binding operations.
+ * Hence buffer storage cannot be accessed properly if managed via native code.

-/**
- * 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.)

+/**
+ * Reads a PNG image, line by line.
+ * <p>
+ * The reading sequence is as follows: <br>
+ * 1. At construction time, the header and IHDR chunk are read (basic image
+ * info) <br>
+ * 2. Afterwards you can set some additional global options. Eg.
+ * {@link #setUnpackedMode(boolean)}, {@link #setCrcCheckDisabled()}.<br>
+ * 3. Optional: If you call getMetadata() or getChunksLisk() before start
+ * reading the rows, all the chunks before IDAT are automatically loaded and
+ * available <br>
+ * 4a. The rows are read onen by one of the <tt>readRowXXX</tt> methods:
+ * {@link #readRowInt(int)}, {@link PngReader#readRowByte(int)}, etc, in order,
+ * from 0 to nrows-1 (you can skip or repeat rows, but not go backwards)<br>
+ * 4b. Alternatively, you can read all rows, or a subset, in a single call:
+ * {@link #readRowsInt()}, {@link #readRowsByte()} ,etc. In general this
+ * consumes more memory, but for interlaced images this is equally efficient,
+ * and more so if reading a small subset of rows.<br>
+ * 5. Read of the last row auyomatically loads the trailing chunks, and ends the
+ * reader.<br>
+ * 6. end() forcibly finishes/aborts the reading and closes the stream

+   * Bug 1036: NVidia Windows Driver 'Threaded optimization' workaround.
+   * <p>
+   * https://jogamp.org/bugzilla/show_bug.cgi?id=1036
+   * </p>
+   * <p>
+   * Since NV driver 260.99 from 2010-12-11 a 'Threaded optimization' feature has been introduced.
+   * The driver spawns off a dedicated thread to off-load certain OpenGL tasks from the calling thread
+   * to perform them async and off-thread.
+   * </p>
+   * <p>
+   * If 'Threaded optimization' is manually enabled 'on', the driver may crash with JOGL's consistent
+   * multi-threaded usage - this is a driver bug.
+   * </p>
+   * <p>
+   * If 'Threaded optimization' is manually disabled 'off', the driver always works correctly.
+   * </p>
+   * <p>
+   * 'Threaded optimization' default setting is 'auto' and the driver may crash without this workaround.
+   * </p>
+   * <p>
+   * If setting the process affinity to '1' (1st CPU) while initialization and launching
+   * the  {@link SharedResourceRunner}, the driver does not crash anymore in 'auto' mode.
+   * This might be either because the driver does not enable 'Threaded optimization'
+   * or because the driver's worker thread is bound to the same CPU.
+   * </p>
+   * <p>
+   * Property integer value <code>jogl.windows.cpu_affinity_mode</code>:
+   * <ul>
+   *   <li>0 - none (no affinity, may cause driver crash with 'Threaded optimization' = ['auto', 'on'])</li>
+   *   <li>1 - process affinity (default, workaround for driver crash for 'Threaded optimization' = 'auto', still crashes if set to 'on')</li>
+   * </ul>
+   * </p>
+   * <p>
+   * Test case reproducing the crash reliable is: com.jogamp.opengl.test.junit.jogl.caps.TestTranslucencyNEWT<br>
+   * (don't ask why ..)

-    NVidia RANDR RefreshRate Bug
-        If NVidia's 'DynamicTwinView' is enabled, all refresh rates are
-        unique, ie consequent numbers starting with the default refresh, ie 50, 51, ..
-        The only way to workaround it is to disable 'DynamicTwinView'.
-        Read: http://us.download.nvidia.com/XFree86/Linux-x86/260.19.12/README/configtwinview.html
-
-        Check to see if 'DynamicTwinView' is enable:
-            nvidia-settings -q :0/DynamicTwinview
-
-        To disable it (workaround), add the following option to your xorg.conf device section:

+/**
+ * 2 pointer scroll/rotate gesture handler processing {@link MouseEvent}s
+ * while producing {@link MouseEvent#EVENT_MOUSE_WHEEL_MOVED} events if gesture is completed.
+ * <p>
+ * Criteria related to parameters:
+ * <pre>
+ *    - doubleTapSlop (scaled in pixels):
+ *       - Max 2 finger distance to start 'scroll' mode
+ *       - Max. distance diff of current 2-pointer middle and initiated 2-pointer middle.
+ *
+ *    - touchSlop (scaled in pixels):
+ *       - Min. movement w/ 2 pointer within ScaledDoubleTapSlop starting 'scroll' mode
+ *
+ *    - Avoid computation if not within gesture, especially for MOVE/DRAG
+ *
+ *    - Only allow gesture to start with PRESS
+ *
+ *    - Leave gesture completely with RELEASE of both/all fingers, or dist-diff exceeds doubleTapSlop
+ *
+ *    - Tolerate temporary lift 1 of 2 pointer
+ *
+ *     - Always validate pointer-id
+ * </pre>
+ * </p>
+ * Implementation uses a n-state to get detect gesture:
+ * <p>
+ * <table border="1">
+ *   <tr><th>from</th>      <th>to</th>   <th>action</th></tr>
+ *   <tr><td>NONE</td>      <td>1PRESS</td>    <td>1-pointer-pressed</td></tr>
+ *   <tr><td>1PRESS</td>    <td>2PRESS_T</td>  <td>2-pointer-pressed within doubleTapSlope</td></tr>
+ *   <tr><td>2PRESS_T</td>  <td>SCROLL</td>    <td>2-pointer dragged, dist-diff within doubleTapSlop and scrollLen >= scrollSlop</td></tr>
+ *   <tr><td>2PRESS_C</td>  <td>SCROLL</td>    <td>2-pointer dragged, dist-diff within doubleTapSlop</td></tr>
+ *   <tr><td>SCROLL</td>    <td>SCROLL</td>    <td>2-pointer dragged, dist-diff within doubleTapSlop</td></tr>
+ * </table>
+ * State ST_2PRESS_C merely exist to pick up gesture after one pointer has been lost temporarily.
+ * </p>
+ * <p>
+ * {@link #isWithinGesture()} returns gestureState >= 2PRESS_C
+ * </p>

+ * If representing a single-pointer {@link PointerType#Mouse} event, {@link #getPointerId(int) pointer-ID} is <code>0</code>

+/**
+ * Difference to orig. Bug735Inv0AppletAWT:
+ * <pre>
+ *   - Use GLEventListener
+ *   - Add GLEventListener to GLAutoDrawable
+ *   - Use GLAutoDrawable.display() instead of GLAutoDrawable.invoke(true, GLRunnable { init / render })
+ *   - Removed MANUAL_FRAME_HANDLING, obsolete due to GLAutoDrawable/GLEventListener
+ *   - Use Animator
+ *   - Remove component sizes, use frame based size via validate
+ *   - Run frame validation/visibility on AWT-EDT
+ *   - Add Wait-For-Key after init (perf-test)
+ *   - Remove intermediate applet!
+ * </pre>
+ * OSX Results:
+ * <pre>
+ *   - Visible content
+ *   - Fluent animation
+ * </pre>

+ * Sample program that relies on JOGL's mechanism to handle the OpenGL context
+ * and rendering loop when using an AWT canvas attached to an Applet.
+ * <p>
+ * BUG on OSX/CALayer w/ Java6:
+ * If frame.setTitle() is issued right after initialization the call hangs in
+ * <pre>
+ * at apple.awt.CWindow._setTitle(Native Method)
+ *  at apple.awt.CWindow.setTitle(CWindow.java:765) [1.6.0_37, build 1.6.0_37-b06-434-11M3909]
+ * </pre>
+ * </p>
+ * <p>
+ * OSX/CALayer is forced by using an Applet component in this unit test.
+ * </p>
+ * <p>
+ * Similar deadlock has been experienced w/ other mutable operation on an AWT Container owning a GLCanvas child,
+ * e.g. setResizable*().
+ * </p>
+ * <p>
+ * Users shall make sure all mutable AWT calls are performed on the EDT, even before 1st setVisible(true) !

+ * This test uses the DDSImage class to read a dds image from file, extract the data,
+ * and use the class to create a new DDSImage from the extracted data
+ * <br></br>
+ * Bug Reference: https://jogamp.org/bugzilla/show_bug.cgi?id=362
+ * <br></br>
+ * The bug pertains to incorrect size calculation for checking validity of data. Compressed DXT1 has min of 8 bytes, DXT5 has min of 16 bytes.
+ * It exists in {@link DDSImage#createFromData(int, int, int, ByteBuffer[])}
+ * where an {@link IllegalArgumentException} is thrown for Mipmap level size mismatch.
+ * <br></br>
+ * <ul>The following cases are tested:
+ * <li>Uncompressed 64x32 RGB DDS Image with all mipmap levels (64x32 --> 1x1)</li>
+ * <li>DXT1 compressed 64x32 RGB DDS Image with all mipmap levels (64x32 --> 1x1)</li>
+ * <li>DXT5 compressed 64x32 RGB DDS Image with all mipmap levels (64x32 --> 1x1)</li>
