Subject: GLAutoDrawable* refinement of abstraction / generalization - API
 Change!

- GLAutoDrawable (compat change - recompile):
  - 'void invoke(boolean wait, GLRunnable glRunnable)' -> 'boolean invoke(boolean wait, GLRunnable glRunnable)'
    Allows notifying caller whether the task has been executed or at least enqueued.

- GLAutoDrawable add 'GLEventListener removeGLEventListener(int index)'
  - This allow one to remove a specific GLEventListener and reusing it (return value).

- GLDrawableImpl remove 'destroy()' to favor 'setRealized(false)'
  - Using more common code of GLAutoDrawableBase, i.e. GLPbufferImpl can use defaultDestroyOp().
  - Removes redundancy of methods

- GLAutoDrawableBase/Delegate
  - better 'default' names to emphasize it's purpose, adding API doc

  - includes more generic functionality
    - defaultWindowDestroyNotify()
    - defaultDestroyOp()

  - TestGLAutoDrawableDelegateNEWT demonstrates a simple example w/ all window events handled.

- Fix TestParenting01cSwingAWT's threading use (gl disturbance thread)

From e85e3ec2a73ac35aaf911f0b1e34b234be1622da Mon Sep 17 00:00:00 2001
From: Sven Gothel <sgothel@jausoft.com>
Date: Fri, 6 Jul 2012 01:20:48 +0200
Subject: Enhance Bootsrapping of JOGL around 37% - 40% (1st start in new JVM)
 - GLProfile and GLContext*

GLProfile: Enhance bootsrapping performance of loading GL*Impl class
  - Offthread classloading of all GL*Impl via reflection at startup
    reduces startup time here around 12% (800ms down to 700ms).

GLContext*: Enhance bootsrapping performance of querying available GL profiles
  - Add PROFILE_ALIASING mode, defaults to true - can be disabled w/ property 'jogl.debug.GLContext.NoProfileAliasing'
  - PROFILE_ALIASING:
      If true (default), bootstrapping the available GL profiles
      will use the highest compatible GL context for each profile,
      hence skipping querying lower profiles if a compatible higher one is found.
        Linux x86_64 - Nvidia: 28%,  700ms down to 500ms
        Linux x86_64 - AMD   : 40%, 1500ms down to 900ms

- GL*Impl:
  - make fields final: glProfile, _context, buffer*Tracker and glStateTracker
  - allow null _context/glProfile in initialization (bootstrapping)

- JoglVersion.getDefaultOpenGLInfo(..)
  - add arg: 'boolean withCapabilitiesInfo', allowing to suppres the list of caps

Subject: Bug 599 - FBObject / Offscreen Support - Part 1

- New FBObject implementation handling FBO and it's attachments  *** API CHANGE: Util -> Core ***
  while it's size and sample-count can be reconfigured on the fly.
    - com.jogamp.opengl.util.FBObject -> com.jogamp.opengl.FBObject
    - agnostic to texture unit
    - separate attachments using OO hierarchy reflecting FBO
    - handling MSAA and blitting
    - no FBO destruction for reconfig (attach/detach)

- New GLFBODrawableImpl impl. an FBObject based GLDrawable
   - Instantiated by a dummy native surface (onscreen and invisible)
     hooked up to a dummy GLDrawable, which is the delegation for context creation.

   - Utilizies ProxySurface.UpstreamSurfaceHook for dummy surface
     avoiding specialization for native platforms.

   - TODO: Allow to utilize common surface interface as a
     dummy-surface to supporting API seperation of
     windowing/GL. The latter allows impl. of createGLDrawable(NativeSurface)
     with FBO.

- New OffscreenAutoDrawable (extends GLAutoDrawableDelegate)
  for all offscreen drawables. Shall replace GLPbuffer.

- New GLCapabilities*.isFBO() / setFBO(boolean) to request FBO offscreen,
  similar to isPBuffer(). Rule: if both are requested, FBO shall be favored.

- GLContext adds raw FBO availability query (min. FBO avail),
  FBObject contains fine grained queries (TODO: Move parts to GLContext for efficiency).

- Add framebuffer tracking, allowing fast querying:
  - GLBase/GLContext:
      public int getBoundFramebuffer(int target);
      public int getDefaultDrawFramebuffer();
      public int getDefaultReadFramebuffer();

  - GLContextImpl
      public final void setBoundFramebuffer(int target, int framebufferName)
      .. called by GL impl bind framebuffer

- GL: getDefaultDrawFramebuffer(), getDefaultReadFramebuffer()
  Adding default framebuffer queries being issued by
  GL.glBindFramebuffer(target, 0) w/ a default framebuffer, o.e. zero.
  This allows a transparent use of a custom FBO even in case the applications
  attempts to reset FBO to zero.
    Value flow: GL <- GLContext <- GLDrawable,

- GLCapabilities handle fbo/pbuffer seperate, don't disable the other

- GLContext/GL track read/write framebuffer to be queried by FBObject
  to determine whether to bind/unbind  a framebuffer

- Test cases for multiple FBO w/ and w/o MSAA

Other Features:

- New interface ProxySurface.UpstreamSurfaceHook,
  allowing to hook an upstream surface of unknown type
  providing lifecycle and information (size, ..) callbacks.
  Used for all new dummy NativeSurface impl and SWT GLCanvas.

  - GLContext -> GLDrawable propagation context/drawable lifecycle
    via ProxySurface.UpstreamSurfaceHook allowing dynamic resources
    to react (create, init, ..)
    - contextRealized()
    - contextMadeCurrent()

- SurfaceChangeable -> MutableSurface
  currently only contains setting the surface handle.

  TODO: May need to move ProxySurface.UpstreamSurfaceHook -> MutableSurface.UpstreamSurfaceHook,
        allowing other impl. classes (NEWT OffscreenWindow) to utilize the new
        upstream hookup mechanism - will allow FBO/Dummy window to work.

- SWT GLCanvas using ProxySurface.UpstreamSurfaceHook for proper size
  propagation.

- New GLAutoDrawable::getUpstreamWidget(), allowing GLEventListener
  to fetch the owning Java side UI element (NEWT, SWT, AWT, ..).

- GLDrawableFactory: Removed createOffscreenSurface() - unused and not GL related

- EGLDrawableFactory handles device/profile avail. mapping
  while actually creating context/drawable.
  This allows us to learn whether the ES context is software/hardware as well as FBO avail.

- EGLDrawable: Removed secret buckets of EGL configs :)
  Employ native surface (X11, WGL, ..) to EGL 'mapping' in
  EGLDrawableFactory utilizing new EGLUpstreamSurfaceHook (implements ProxySurface.UpstreamSurfaceHook).

Other Bugs:

- Add CTX_OPTION_DEBUG to ctx/extension cache key since only a debug ctx
  may expose the ARB debug capability.
  This bug caused lack of ARB/AMD debug functionality.

- Fix GLProfile deadlock (debug mode, w/ EGL/ES, no X11),
  dump availability information _after_ lock.

- ImmModeSink draw(): Use GL's glDrawElements(..), don't cast for GL2ES1.
  Fixes use for GL2ES2.

- Fix KeyEvent.getKeyChar() comment (-> only stable for keyTyped(..))

Misc:

- Refined alot of API doc

- New GLExtensions holds commonly used GL extension strings,
  allows better referencing and usage lookup.

- Move GL (interface) decl. to GLBase

- GLBuffers: Cleanup API doc (format, types)

- TextureIO: Add PAM and PPM static suffix identifier

- GLCapabilities getNumSamples() returns 0 if sampleBuffers is disabled, this seems to be more natural.

- finalized a lot

 WIP:
 
+- GLPbuffer -> GLOffscreenAutoDrawable
+    - GLPbuffer GLDrawableFactory.createPbuffer() ->
+      GLOffscreenAutoDrawable GLDrawableFactory.createOffsceenAutoDrawable()
+    - Mark both deprecated!
+
 Random, somewhat old to-do list:
 
 - Non-const array types must be properly released with JNI_COMMIT in
   order to see side effects if the array was copied.
 
-- figure out how to deal with WGL entry points:
-    WINGDIAPI HGLRC WINAPI wglCreateLayerContext(HDC, int);
-    WINGDIAPI BOOL  WINAPI wglUseFontBitmapsA(HDC, DWORD, DWORD, DWORD);
-    WINGDIAPI BOOL  WINAPI wglUseFontBitmapsW(HDC, DWORD, DWORD, DWORD);
-  see commented-out section in make/stub_includes/win32/wingdi.h
-
 - Need a disciplined mechanism for converting char* argument types. For
   example, many C functions accept a "char*" argument with the semantic that
   output data will be written into the buffer pointed to by the

Subject: Fix Bug 606 - New AWT threading implementation breaks .. ; Fix
 GLAutoDrawable multi-threading w/ proper pattern (hope so)

Considering code changes and remarks:
  3ed491213f8f7f05d7b9866b50d764370d8ff5f6
  1a91ec5c8b6fd9d9db7bc115569c369fe7b38e9b
  3334a924309a9361a448d69bc707d4cce416b430
  4f27bcecf7484dc041551f52a5c49e2884cb3867

It seems necessary to have

- recursive locking employed for all semantic actions which changes drawable & context (and the Window resource)

- to avoid deadlock, we have to ensure the locked code segment will not spawn
  off to another thread, or a thread holds the lock, spawns of an action requiring the lock. .. sure

- other read-only methods (flags, ..) shall at least utilize a safe local copy of a volatile field
  if further use to produce the result is necessary.

- flags like sendReshape require to be volatile to guarantee it's being processed

Patch impacts: AWT/SWT GLCanvas, GLAutoDrawableBase [and it's specializations]
and hopefully closes any loopholes of missing a cache hit, etc.

If you review this and find optimizations, i.e. removing a lock due to semantics etc,
don't hold back and discuss it, please.

Subject: Fix GraphicsConfigurationFactory: Map factory to device-type _and_
 capabilities-type; Add a pre-set nativeVisualID to
 chooseGraphicsConfiguration(..)

Map factory to device-type _and_ capabilities-type:
  - Allows using different GraphicsConfigurationFactory implementations for different capabilities-types.
    Previous impl. failed to use an OpenGL agnostic CapabilitiesImmutable for 'chooseGraphicsConfiguration(..)'
    since only the GL aware factory was mapped. The latter failed since it expected a GLCapabilitiesImmutable.

  - The passed capabilities-type as well as device-type given at getFactory(..)
    is traversed top-to-down to find a most suitable factory:
        For-All devT := getTopDownDeviceTypes(deviceType)
            For-All capsT := getTopDownCapabilitiesTypes(capabilitiesType)
               f = factory.get(devT, capsT);
               if(f) { return f; }
            end
        end

Add a pre-set nativeVisualID to chooseGraphicsConfiguration(..)
  - In situations where a native visualID is already chosen [by external means for example],
    but we still need to query a matching GraphicsConfiguration - we require to pass
    a non VisualIDHolder.VID_UNDEFINED nativeVisualID.

    We had a hack implemented before within some implementations and their static calls,
    however an agnostic mechanism is required to implement new NativeSurface/Window's
    platform agnostic.

  - X11GLXGraphicsConfigurationFactory: respect a pre-set xvisualID

  - X11GLXDrawableFactory.createProxySurfaceImpl(..) queries the given windowHandle's
    visualID and 'chooses' the configuration accordingly. If the visualID is undefined
    an exception is thrown, since window is invalid.
    These mechanics are implicit for Windows and OSX.

Fix X11GLXGraphicsConfiguration.updateGraphicsConfiguration():
  - Skip any action if a valid X11GLCapabilities is already chosen, i.e. w/ visualID.
    Otherwise choose a suitable configuration incl. visualID.
    The latter is quite impossible and invalid, since visualID must be defined at window creation time
    and the update method is issued with a valid window.

X11 - Misc:
  - Added 'int jogamp.nativewindow.x11.X11Lib.GetVisualIDFromWindow(..)'

  - All returned visualID's are of type 'int'

Subject: Fix GLCanvas's JAWTWindow reference ; Add ES2 test in TestAWT01GLn ;
 Ubuntu 12.04/Pandaboard(Omap4, PowerVR SGX 540) 103/108 tests passed (before
 freeze) of 124 total

Fix GLCanvas's JAWTWindow reference
  - drawable.getNativeSurface() may not be a JAWTWindow
    due to our EGL WrappedSurface. Hence store the created JAWTWindow reference locally.

Add ES2 test in TestAWT01GLn
  - test EGL/ES2 w/ AWT GLCanvas

Ubuntu 12.04/Pandaboard(Omap4, PowerVR SGX 540): 103/108 tests passed (before freeze) of 124 total
  - machine freezes around test 108 ..
  - new passed unit test high for ES2 incl. AWT tests

Subject: Seamless Integration of an FBObject based GLFBODrawable as
 GLOffscreenAutoDrawable.FBO and as an OffscreenLayerSurface's drawable (OSX)
 - Fix Bugs 569 and 599

Summary:
=========
The new FBObject based GLFBODrawable implementation allows the seamless utilization of
FBO offscreen rendering in single buffer, double buffer and MSAA mode.

The GLFBODrawable uses a parent drawable based on a
dummy surface to allow a GLOffscreenAutoDrawable.FBO creation
or a mutable surface supporting an existing offscreen layer surface (OSX CALayer).

Offscreen GLDrawable's and GLOffscreenAutoDrawable's can be selected via the
GLCapabilities. If simply !onscreen is selected in the caps instance w/o enabling FBO, PBuffer or Bitmap,
the factory will automatically choose regarding availability:
   FBO > PBuffer > Bitmap

Double buffering is supported in MSAA more (intrinsic) and explicit in non MSAA.
It is preferred when delivering resources (texture id's or framebuffer names)
to a shared GLContext.
This is demonstrated in (emulates our OSX CALayer implementation):
  TestFBOOffThreadSharedContextMix2DemosES2NEWT,
  TestFBOOnThreadSharedContext1DemoES2NEWT
and with the OSX JAWT OffscreenLayerSurface itself. FBO is the preferred choice.

+++

Offscreen drawables can be resized while maintaining a bound GLContext (e.g. w/ GLAutoDrawable).
Previously both, drawable and context, needed to be destroyed and recreated at offscreen resize.
Common implementation in GLDrawableHelper is used in the implementations
(NEWT's GLWindow, AWT GLCanvas, SWT GLCanvas).

+++

Tested:
=======

Manually run all unit tests on:
  - Linux x86_64 NVidia/AMD/Mesa3d(ES)
  - OSX x86_64 NVidia
  - Windows x86_64 NVidia
  - Android arm Mali-400/Tegra-2

No regressions.

Disclaimer:
===========
This feature is committed almost in one patch.

Both previous commits were introducing / fixing the capabilities behavior:
 90d45928186f2be99999461cfe45f76a783cc961
 9036376b7806a5fc61590bf49404eb71830de92f

I have to appologize for the huge size and impact (files and platforms) of this commit
however, I could not find a better way to inject this feature in one sane piece.

NativeWindow Details:
=====================

Complete decoupling of platform impl. detail of surfaces
implementing ProxySurface. Used to generalize dummy surfaces and EGL surfaces
on top of a native platform surface.
  - ProxySurface.UpstreamSurfaceHook -> UpstreamSurfaceHook
  - abstract class ProxySurface -> interface ProxySurface + ProxySurfaceImpl
  - Misc. implementations

JOGL Details:
=====================

FBOObject: API Change / Simplification & Usability
  - Removed reference counter to remove complexity, allow user to choose.
  - Add 'dispose' flag for detachColorbuffer(..), allowing to keep attachment alive
  - Fix equals operation of Attachment
  - Check pre-exising GL errors
  - Interface Colobuffer gets lifecycle methods
  - Add static factory methods to create Attachments w/o FBObject instance
  - Reset:
    - Clip min size to 1
    - Keep alive samplingSink, i.e. don't issue resetMSAATexture2DSink(..).
      It gets called at syncFramebuffer()/use(..) later on before actual usage.
      This allows the consumer to utilize the GL_FRONT buffer until (e.g.) swap.
  - misc bugfixes

GLOffscreenAutoDrawable: API Change
  - Reloc and interfacing
  - class com.jogamp.opengl.OffscreenAutoDrawable -> javax.media.opengl.*
    interfaces GLOffscreenAutoDrawable extends GLAutoDrawable
               GLOffscreenAutoDrawable.FBO extends GLOffscreenAutoDrawable, GLFBODrawable
  - Added general implementation and FBO specialization
  - Replacing GLPBuffer (deprecated) .. usable for any offscreen GLDrawable via factory

GLAutoDrawable:
  - Add 'GLDrawable getDelegatedDrawable()'
  - Refine documentation of setContext(..), remove disclaimer and fixme tags

GLDrawableFactory:
  - Refine API doc and it's selection mechanism for offscreen.
  - Add createOffscreenDrawable(..)
  - Add createOffscreenAutoDrawable(..)
  - Add canCreateFBO(..)
  - Mark createGLPbuffer(..) deprectated

Mark GLPBuffer deprecated

New: GLFBODrawable extends GLDrawable

GLCanvas (AWT and SWT): Add offscreen resize support w/o GLContext recreation

GLAutoDrawableBase .. GLWindow:
  - Add offscreen resize support w/o GLContext recreation
  - Remove double swapBuffer call
  -

GLBase/GLContext:
  - Add:
    - boolean hasBasicFBOSupport()
    - boolean hasFullFBOSupport()
    - int getMaxRenderbufferSamples()
    - boolean isTextureFormatBGRA8888Available()

GLContext: Fix version detection and hasGLSL()
  - Version detection in setGLFunctionAvailability(..)
    - Query GL_VERSION ASAP and parse it and compare w/ given major/minor
    - Use parsed version if valid and lower than given _or_ given is invalid.
    - Use validated version for caching (procaddr, ..), version number, etc.

  - Fix hasGLSL()
    Since 'isGL2ES2()' is true if 'isGL2()'
    and the latter simply alows GL 1.*, we confine the result to a GL >= 2.0
    on desktops. FIXME: May consider GL 1.5 w/ extensions.
    -  return isGL2ES2();
    +      return isGLES2() ||
    +             isGL3() ||
    +             isGL2() && ctxMajorVersion>1 ;

GLDrawableImpl:
  - Add 'associateContext(GLContext, boolean)' allowing impl.
    to have a (weak) reference list of bound context.
    This is was pulled up from the OSX specific drawable impl.
  - swapBuffersImpl() -> swapBuffersImpl(boolean doubleBuffered)
    and call it regardless of single buffering.
    This is required to propagate this event to impl. properly,
    i.e. FBODrawable requires a swap notification.
  - Clarify 'contextMadeCurrent(..)' protocol

GLDrawableHelper:
  - Add resize and recreate offscreen drawable util method
  - Simplify required init/reshape calls for GLEventListener
  -

GLGraphicsConfigurationUtil:
  - fixWinAttribBitsAndHwAccel: Reflect sharede context hw-accel bits
  - OSX has no offscreen bitmap, use pbuffer
  - use proper offscreen auto selection if offscreen and no modes are set

EGL Context/Drawable/DrawableFactory: Abstract native platform code out of base classes
  - Use EGLWrappedSurface w/ UpstreamSurfaceHook to handle upstream (X11, WGL, ..)
    lifecycle - in case the EGL resource is hooked up on it.

Invisible dummy surfaces: All platforms
  - size is now reduced to 64x64 and decoupled of actual generic mutable size
  - fix device  lifecycle, no more leaks

+++

OSX
====

Enable support for GLFBODrawableImpl in offscreen CALayer mode
  - NSOpenGLImpl: hooks to calayer native code
  - calayer code:
    - allows pbuffer and texures (FBO)
    - decouple size and draw calls avoiding flickering
    - enable auto resize of calayer tree

MacOSXCGLContext:
  - NSOpenGLImpl:
  - Fix false pbuffer 'usage', validate the pointer
  - If !pbuffer, copy other window mode bits of caps
  -

MacOSXCGLGraphicsConfiguration:
  - Only assume pbuffer if !onscreen
  - Remove reference of native pixelformat pointer

Native code:
  - use 'respondsToSelector:' query before calling 'new' methods
    avoiding an error message where unsuported (prev. OSX versions)
  - if monitor refresh-rate is queried 0, set to default 60hz
  - add missing NSAutoreleasePool decoration

+++

Android / NEWT:
===============

Issue setVisible(..) w/o wait, i.e. queue on EDT,
@Android surfaceChanged() callback. Otherwise we could deadlock:
   setVisible(..) -> EDT -> setVisibleImpl(..) -> 'GL-display'.
the latter may may cause havoc while Android-EDT is blocked [until it's return].

Subject: Fix Bug 572 (2nd time): GLCanvas.validateGLDrawable() @ display() and
 reshape() ; GLCanvas.reshape() only if drawble valid ;
 GLCanvas.validateGLDrawable() also test isDisplayable() ; Fix size validation
 ; resizeOffscreenDrawable(..) don't validate 'safe' size 1x1

- GLCanvas.validateGLDrawable() @ display() and reshape()
  To help users using GLCanvas w/ having a realized GLCanvas/Drawable,
  validateGLDrawable() is also called at reshape().
  This shall ensure a valid drawable after even a non AWT-EDT issued first setVisible().

- GLCanvas.reshape() only if drawble valid
  Otherwise offscreen reshape attempts would happen even on unrealized drawable,
  which is not necessary.

- GLCanvas.validateGLDrawable() also test isDisplayable()
  To make sure the native peer is valid, also test isDisplayable()

- Fix size validation
  Since we have experienced odd size like 0 x -41
  test each component, i.e. 0 < width && 0 < height.
  This is done through all JOGL/NEWT components.

- resizeOffscreenDrawable(..) don't validate 'safe' size 1x1
  In case method is called w/ odd size, i.e. 0 x -41,
  the safe size 1x1 is used. However, we cannot validate this size.
  Dump WARNING if odd size is detected.

Subject: Refine a3cb6bb14f410f67fccf5ccd4cd7ecc66f448389, fix deadlock
 (regression)

The lock being claimed at validateGLDrawable() is 'offthread', i.e. may fight w/ AWT / Animator
at reshape/display.

Locking is moved 'down' to AWT runnable 'setRealizedOnEDTAction', which also double checks
the drawable [again].

Subject: GLAutoDrawable: Fix GLEventListener lifecycle and expose more user
 control (API Change) ; Added GLDrawableUtil

A GLEventListener resides in two states, initialized and uninitialized.
When added to a GLAutoDrawable, it is uninitialized.
A first 'display()' will issue GLEventListener's 'init(..)' which renders it initialized.
This is usually accompanied by 'reshape(..)' propagating the drawable's dimension.

Destruction of the GLAutoDrawable will issue GLEventListener's 'dispose(..)' which renders it uninitialized.

It turns our these means of GLEventListener controls are not sufficient in case
the user requires to remove and add them during the lifecycle and rendering of their GLAutoDrawable host.
GLAutoDrawable 'removeGLEventListener(..)' merely removes the GLEventListener from the list,
but does not complete it's lifecycle, i.e. issues 'dispose(..)' if initialized to realease GL related resources.

Hence the following essential API changes are made to complete the lifecycle:

+  public GLEventListener disposeGLEventListener(GLEventListener listener, boolean remove);

   disposing a single GLEventListener, allowing it's removal from the list being optional

This is demonstrated via GLDrawableUtil.swapGLContextAndAllGLEventListener(GLAutoDrawable a, GLAutoDrawable b), see below.

++++++++

Further more the following API changes were made to expose complete control of
GLEventListener to the user:

-  public void removeGLEventListener(GLEventListener listener);
+  public GLEventListener removeGLEventListener(GLEventListener listener);

   The return value allows simple pipelining, and also delivers information whether
   the passed listener was actually removed.

-  public GLEventListener removeGLEventListener(int index) throws IndexOutOfBoundsException;
+  public int getGLEventListenerCount();
+  public GLEventListener getGLEventListener(int index) throws IndexOutOfBoundsException;

   Dropping the redundant removal by index, while adding count and get methods.

+  public boolean getGLEventListenerInitState(GLEventListener listener);
+  public void setGLEventListenerInitState(GLEventListener listener, boolean initialized);

   Allows retrieving and setting of listener states.

All in all these API changes allows a user to experience all freedoms in dealing w/
GLEventListeners hosted by GLAutoDrawable impl. and shall be future proof.

Note that we have avoided the Iterator pattern due to it's overhead of temporal objects creation.
The simple indexed access allows us to implement each method as an atomic operation.

+++++++++++

Further more a simple enqueue(..) method has been added, allowing to just enqueue a GLRunnable
w/o provoking it's execution - as invoke(..) does.
This method pleases a use case where GLRunnables are batched and shall be executed later on..

   public boolean invoke(boolean wait, GLRunnable glRunnable);
+  public void enqueue(GLRunnable glRunnable);

+++++++++++

Added GLDrawableUtil, exposes utility function to rearrange GLEventListener, modifiy GLAutoDrawable, etc.

GLDrawableUtil.swapGLContextAndAllGLEventListener(GLAutoDrawable a, GLAutoDrawable b)
is tested and demonstrated w/ TestGLContextDrawableSwitchNEWT.

Manually tested on X11, OSX and Windows.

Subject: GLAutoDrawable: Refine API change of commit
 c002e04f848116922a1ed7bd96ead54961649bbd

As suggested by Julien Gouesse, align 'enqueue(..)' method w/ 'invoke(..)':

-  public void enqueue(GLRunnable glRunnable);

+  public boolean invoke(boolean wait, List<GLRunnable> glRunnables);

Subject: Fix GLAutoDrawable.dispose(): Dispose drawable even w/o context;
 JAWTWindow.lockSurface(): Check AWT component's native peer

- Fix GLAutoDrawable.dispose(): Dispose drawable even w/o context
  - It is possible to have the GLContext not being created (not made current),
    so drawable shall be disposed independent.

  - Merge Runnable 'postDisposeOnEDTAction' to dispose Runnable for clarity

  - GLDrawableHelper: Split disposeGL from invokeGLImpl for clarity

- JAWTWindow.lockSurface(): Check AWT component's native peer
  - W/o a native peer (!isDisplayable()), JAWT locking cannot succeed.

  - On OSX OpenJDK 1.7, attempting to JAWT lock a peer-less component crashes the VM

  - MacOSXJAWTWindow.lockSurfaceImpl(): Remove redundant null checks

Subject: Cleanup GLContext special entries:
 getOffscreenContextPixelDataType(), getOffscreenContextReadBuffer(), .. ; Add
 GLFBODrawable API entries for multi buffering (no impl. yet); GLJPanel 1st
 simplification using offscreen drawable

- Cleanup GLContext special entries: getOffscreenContextPixelDataType(), getOffscreenContextReadBuffer(), .. ;
  - add: getDefaultReadBuffer() (-> exposed via GLBase as well)
  - add: isGLOrientationFlippedVertical()
  - add: getDefaultPixelDataType()
  - removed impl: getOffscreenContextPixelDataType()
  - removed impl: getOffscreenContextReadBuffer()
  - removed impl: offscreenImageNeedsVerticalFlip()

- Add GLFBODrawable API entries for multi buffering (no impl. yet);
  - TODO: Add implementation code in GLFBODrawableImpl

- GLJPanel 1st simplification using FBO
  - Use above new GL/GLContext entries
  - Fix: getNativeSurface() and getHandle()
  - TODO:
    - Remove distinction of 'pbuffer' and 'software',
    - Use GLDrawableFactory.createOffscreenDrawable(..)
    - Use GL for FBO swapping

Subject: GLJPanel: Impl. is GLProfile agnostic; Use
 GLDrawableFactory.createOffscreenDrawable(..) for common OffscreenBackend
 (dropping pbuffer/software); Flip FBO w/ GLSL texture renderer.

- Implementation is GLProfile agnostic
  - Shall work on ES2, GL2, .. etc

- Use GLDrawableFactory.createOffscreenDrawable(..) for common OffscreenBackend (dropping pbuffer/software)
  - Leave offscreen selection to common factory code, favoring FBO

- Flip FBO w/ GLSL texture renderer
  - Faster on low CPU machines
  - Enabled if GL2ES2 and FBO offscreen

Subject: Fix Bug 642 TestJSplitPaneMixHwLw01AWT (AWT-GLCanvas); Robustness
 GLContext/GLDrawable

- Fix Bug 642 TestJSplitPaneMixHwLw01AWT
  On Windows platform when mixing hw/lw JSplitPanel,
  the GLCanvas is removed and added when splitter is moved.
  The lack of robustness (see below) lead to an exception.

  Note: Only w/ GLJPanel (no hw/lw mixing) the splitter can be moved
  in both direction. Only here it is guaranteed that the GL component
  will survive the action.

- Fix AWT-GLCanvas EDT Runnable: swapBuffer().. / display(..)
  - Check drawable.isRealized() within the lock on the performing thread.
    This is not possible before issuing the EDT Runnable action
    since we cannot hold the lock beforehand.

- Robustness GLDrawableImpl
  - boolean realized -> volatile boolean realized
  - remove 'synchronized' on isRealized() and setRealized(..)
  - Use dbl-checked locking on 'realized' test for swapBuffers() and setRealized(..)

- Robustness GLContextImpl
  - Catch createImpl(..) exception and properly return CONTEXT_NOT_CURRENT

Subject: Bug 642 / Refine 1ae0737f34143a5ed655bd9c4d5fe9b0437c7774:
 GLCanvas.displayOnEDT: Also check null!=drawable

As for 1ae0737f34143a5ed655bd9c4d5fe9b0437c7774, an animator may inject a display Runnable on the EDT
before AWT destruction. In case this Runnable is executed after destruction on the EDT - it would fail.

Subject: AWT GLCanvas: More strict GLDrawable realization [on AWT-EDT], skip
 if creation is not possible on AWT-EDT.

The Intel HD3000 OpenGL driver on Windows will deadlock @ SwapBuffers in case the drawable is created
on a thread other than the window owner thread.

We are aware of such possibilities, nevertheless the AWTEDTExecutor.singleton.invoke(..)
allowed to execute the runnable in case it cannot be invoked on AWT-EDT.
The latter is the case if the current thread is not the AWT-EDT _and_ is holding the AWT tree-lock.

With GlueGen commit 0b43b43f889ad7fc220942b0076e2001ca3cf13f, the invoke method now consumes
an argument allowing to restrict the execution to AWT-EDT only.

In such case, the drawable will be realized at a later time from the AWT-EDT.

Such a situation could be triggered if a Frame's setVisible(true)
is not issued from the AWT-EDT, as it should be!
However, to relax such use cases - we better recognize such possible dealock and avoid it.

Subject: GLAutoDrawable/AnimatorBase: Add ExclusiveContextThread (ECT)
 feature; AnimatorBase: Add setModeBits/MODE_EXPECT_AWT_RENDERING_THREAD;
 FPSAnimator: Make transactions deterministic.

ExclusiveContextThread (ECT) allows user to dedicate a GLContext to a given thread.
Only the ECT will be allowed to claim the GLContext, hence releasing must be done on the ECT itself.

The core feature is accessible via GLAutoDrawable, while it can be conveniently enabled and disabled
via an AnimatorBase implementation. The latter ensures it's being released on the ECT and waits for the result.

Note that ECT cannot be guaranteed to work correctly w/ native (heavyweight) AWT components
due to resource locking and AWT-EDT access. This is disabled in all new tests per default and
noted on the API doc.

Note: 'Animator transaction' == start(), stop(), pause(), resume().

- Add ExclusiveContextThread (ECT) feature
  - GLAutoDrawable NEW:
    - Thread setExclusiveContextThread(Thread t)
    - Thread getExclusiveContextThread()

  - AnimatorBase NEW:
    - Thread setExclusiveContext(Thread t)
    - boolean setExclusiveContext(boolean enable)
    - boolean isExclusiveContextEnabled()
    - Thread getExclusiveContextThread()

- AnimatorBase: Add setModeBits/MODE_EXPECT_AWT_RENDERING_THREAD
  Allows user to pre-determine whether AWT rendering is expected before starting the animator.
  If AWT is excluded, a more simple and transaction correct impl. will be used.

- FPSAnimator: Make transactions deterministic.
  FPSAnimator previously did not ensure whether a transaction was completed.
  A deterministic transaction is required to utilize ECT.
  FPSAnimator now uses same mechanism like Animator to ensure completeness,
  i.e. Condition and 'finishLifecycleAction(..)'. Both are moved to AnimatorBase.

Tested manually on Linux/NV, Linux/AMD, Windows/NV and OSX/NV.
  - All new tests validated correctness.

Subject: Java2D OGLPipeline(GLJPanel+Threading): More fine grained control
 about OGL threading and resource usage

- Still excluse OSX
- Respect sun.java2d.opengl property
- [Prepare] Allowing OGLPipeline thread usage w/o it's OGL resource usage

Subject: Fix Bug 675: NPE w/ Beans.setDesignTime(true) ; Fix
 GLCanvas.destroy(): Don't issue removeNotify(), delete drawable and context
 only!

- Fix Bug 675: NPE w/ Beans.setDesignTime(true)
  - Carefully consider Beans.isDesginTime() fixes NPE - added unit test

- Fix GLCanvas.destroy(): Don't issue removeNotify(), delete drawable and context only!
  - AWT removeNotify() shall only be issued via AWT itself, not manually
  - Add 'destroyImpl(boolean destroyJAWTWindowAndAWTDevice)' to be called by
    - GLCanvas.destroy(): destroyImpl( false );
    - GLCanvas.removeNotify(): destroyImpl( true );
  - Ensures JAWTWindow and AWTDevice are created and destroyed via the AWT callbacks
    addNotify() and removeNotify() only.

From 14b278536e6f8de2ee6254796b89bd27d5419b72 Mon Sep 17 00:00:00 2001
From: Sven Gothel <sgothel@jausoft.com>
Date: Wed, 20 Feb 2013 21:51:40 +0100
Subject: OSX/Java7/CALayer + JAWT: Partially Fix AWT/NEWT CALayer 'out of
 sight' bug, where our CALayer is moved out of the visible area

- same erroneous behavior for GLCanvas and NewtCanvasAWT

- sized-frame: Set framesize and validate() it

- sized-component: Set component preferred size and call frame.pack()

- added workaround 'OffscreenLayerSurface.layoutSurfaceLayer()' to fix CALayer size, which snaps for:

  - OK initial size before setVisible: sized-frame and sized-component

  - OK resize w/ sized-frame

  - OK manual frame resize

  - Invisible: w/ sized-component after setVisible()

++

- CALayer-Sublayer (GL) has additional retain/release when added/removed
  to be on safe side.

From: Sven Gothel <sgothel@jausoft.com>

Subject: Fix NEWT/AWT WindowClosing Unit Tests ; Review/Cleanup NEWT
 WindowClosing mechanism

Due to a NEWT WindowClosing event regression cause by NewtCanvasAWT changes
a review of our WindowClosing event mechanism was required.

Important cleanups are marked w/ '(*)' below.

I would have preferred to change the 'WindowListener.windowDestroyNotify(WindowEvent)'
method to pass a WindowCloseEvent object exposing more information like
toolkit or programmatic destruction and passing whether a 'closing' or 'nop' action
will be performed based on the WindowClosingMode.
For now I postponed this idea .. since it would change the API again,
but may reconsider it after merging the Android 'closing' patch.

- InputEvent.consumedTag -> NEWTEvent.consumedTag

- Window
  - (*) Promote setWindowDestroyNotifyAction(Runnable) to public,
        former WindowImpl.setHandleDestroyNotify(boolean).
    Using a Runnable action for WindowImpl.windowDestroyNotify(boolean)
    allows a setting defined alternative for destroy() and gets rid
    of [ab]using WindowListener.windowDestroyNotify(WindowEvent) for
    lifecycle actions. Used in:
      - GLWindow
      - GLAutoDrawableDelegate impl.

- WindowImpl
  - Respect NEWTEvent.consumedTag for WindowEvents as well

  - (*) Impl. setHandleDestroyNotify(boolean) (see above)

  - (*) destroy() simply sends out pre- and post- destruction Window events,
    where windowDestroyNotify(boolean) sends out the pre-destruction event if NOP.

  - (*) windowDestroyNotify(boolean) is public now, allowing other impl. details
    to follow proper destruction using handleDestroyNotify Runnable (-> NewtCanvasAWT).

- AWTWindowClosingProtocol:
  - addClosingListenerOneShot() -> addClosingListener()
    - calling addClosingListener() at addNotify()
    - calling removeClosingListener() at removeNotify()

  - AWTWindowClosingProtocol ctor taking NOP runnable,
    allowing to send WindowEvent.EVENT_WINDOW_DESTROY_NOTIFY at WindowClosingMode.DO_NOTHING_ON_CLOSE

  - add/remove listener on AWT-EDT

- AWTWindowAdapter
  - Add 'removeWindowClosingFrom(..)',
    allowing to remove window closing event fwd.

  - Also fwd windowClosed in window closing fwd'ing.

- NewtCanvasAWT
  - (*) Utilize AWTWindowClosingProtocol NOP runnable (see above)
    to fwd closing-NOP event to NEWT

  - (*) Unify remove/destroy code in destroyImpl(..)
    - !removeNotify -> destroy NEWT child programatic or as toolkit event
    - removeNotify || windowClosing -> destroy jawtWindow

  - (*) Remove AWTWindowAdapter/AWTParentWindowAdapter's windowClosingListener,
    since we utilize AWTWindowClosingProtocol

- DisplayImpl
  - Adding 'final void dispatchMessage(final NEWTEvent event)'
    allowing to remove the NEWTEventTask wrapping for no reason
    in enqueueEvent(..) if on EDT and waiting.

Subject: GLJPanel: Add DEBUG_VIEWPORT flag, Add USE_GLSL_TEXTURE_RASTERIZER
 flag, DEBUG reshape trace.

- Add DEBUG_VIEWPORT flag
  Via explicit property 'jogl.debug.GLJPanel.Viewport' (not via jogl.debug=all)
  Traces the current GL Viewport in OffscreenBackend.postGL(..)

- Add USE_GLSL_TEXTURE_RASTERIZER flag
  Via explicit property 'jogl.gljpanel.noglsl'.
  Disables use of GLSL FBO flipping.

DEBUG reshape trace

Subject: Bug 665: Allow re-association of GLContext/GLEventListener to a
 GLDrawable (Part 4)

Note:

  - GLEventListenerState preservs the GLAutoDrawable state,
    i.e. GLContext, all GLEventListener and the GLAnimatorControl association.

  - GLEventListenerState may be utilized to move the state from a dying GLAutoDrawable,
    to be moved to a new created GLAutoDrawable at a later time.

  - GLEventListenerState will be made public soon.

+++

Exessive unit tests cover the new feature, tested manually on GNU/Linux/X11 and OSX(Java6/Java7).

+++

- GLAutoDrawable
  - Change 'setContext(..)' to allow the destruction of the unbound old context:
      'setContext(GLContext newCtx)' -> 'setContext(GLContext newCtx, boolean destroyPrevCtx)'

  - Implementations: Properly implement 'setRealized(..)' incl. obeying threading constraints if exists.
    Method is being utilized at least for GLEventListenerState.moveTo(..)
    to unrealize and realize the drawable resources.

+++

Fix propagation of GLContext/GLDrawable association change (Bottom -> Top):

  GLDrawableImpl.associateContext
      GLContextImpl.associateDrawable
          GLContextImpl.makeCurrent
          GLContextImpl.destroy
          GLContext.setGLDrawable
              ...
              GLDrawableHelper.switchContext
                  GLAutoDrawble.setContext

associateDrawable(..)/associateContext(..) unifies and hence:
    - GLContextImpl.contextRealized() (removed)
    - GLDrawableImpl.contextRealized() (removed)
    - GLDrawableImpl.associateContext(..) (merged)
    - MacOSXCGLContext.drawableChangedNotify(..) (removed)

+++

- EGLUpstreamSurfaceHook.evalUpstreamSurface() validates the surface's device for reusage,
  which is valid in case of GLEventListenerState.moveTo(..)

- MacOSXCGLContext.NSOpenGLImpl: pixelFormat replaces NSOpenGLLayerPfmt and has simplified lifecycle [create..destroy],
  while native NSOpenGLLayer code only holds the reference until released.

Subject: OSX/CALayer: Simplify FixCALayerLayout()/layoutSurfaceLayer() call,
 no more need for explicit call

- OffscreenLayerSurface.layoutSurfaceLayer() removed, no more required

- JAWTWindow adds a ComponentListener, which issues FixCALayerLayout() at resized, moved and shown.

- MyNSOpenGLLayer no more requires fix*Size() methods

- MyNSOpenGLLayer::setDedicatedSize() need no explicit CATransaction, performed by caller.

Subject: Remodel OSX/CALayer Threading (commit
 896e8b021b39e9415040a57a1d540d7d24b02db1): Run on main-thread w/o blocking ;
 Misc Changes

Commit 896e8b021b39e9415040a57a1d540d7d24b02db1 moved all native CALayer calls to the current thread
to avoid deadlocks.

Even though this seemed to be fine at least resource GC (release/dealloc calls) were issued
very late in time, probably due to multithreading synchronization of JAWT and/or OSX API.

Example: Our 'TestAddRemove01GLCanvasSwingAWT' test didn't freed CALayer resources incl. GL ctx
         when destroying the objects (AWT Frame, GLCanvas, ..), leading to resource starvation .. eventually.

Remedy is a compromise of behavior before commit 896e8b021b39e9415040a57a1d540d7d24b02db1
and that commit, i.e. to run CALayer lifecycle methods on main-thread, but do not block!

The careful part within MacOSXCGLContext.associateDrawable(..) performs the following block on main-thread:
  - lock the context
  - create NSOpenGLLayer (incl. it's own shared GL context and the DisplayLink)
  - attach NSOpenGLLayer to root CALayer
  - unlock the context

Due to the GL ctx locking, this async offthread operation is safe within our course of operations.

Details:
  - NSOpenGLContext
    - Context and CVDisplayLink creation at init
    - Call [ctx update] if texture/frame size changed
    - 'waitUntilRenderSignal' uses default TO value if given TO is 0 to avoid deadlocks

+++

Misc Changes:
  - Fix object type detection: isMemberOfClass -> isKindOfClass
    - OSXUtil_isNSView0
      OSXUtil_isNSWindow0,
      CGL_isNSOpenGLPixelBuffer

  - MacOSXCGLDrawable/MacOSXPbufferCGLDrawable: remove getNSViewHandle() method.
    MacOSXCGLContext uses common code to detect nature of the drawable handle.

  - MacOSXCGLContext/CALayer: Use safe screenVSyncTimeout values, never 0 to avoid deadlock!

  - JAWTWindow.invalidate: Call detachSurfaceLayer() if not done yet

Subject: Fix Bug 720: Unify all platform specific GLContextImpl
 specializations; Fix Bug 719 - Windows BITMAP Offscreen Orientation is not
 propagated through API

Fix Bug 719 - Windows BITMAP Offscreen Orientation is not propagated through API
  Depends on Bug 720, since cleaning up GLContextImpl* is required to move
  property 'GLContext.isGLOrientationFlippedVertical()'
  to 'GLDrawable.isGLOriented()' where it belongs!

  Windows BITMAP GLDrawable impl. isGLOriented() shall return false,
  while we keep the BITMAPINFOHEADER's height field negative
  to remove the need for vertical flip when used w/ AWT or Windows, ..

  Then property 'GLDrawable.isGLOriented()' has to be recognized throughout the
  utility functions, i.e. TextureData's mustFlipVertically and hence TextureIO writer.

Fix Bug 720: Unify all platform specific GLContextImpl specializations
  GLContextImpl shall have only _one_ unique platform derivative
  to allow proper swapping of GLDrawables of any type via:
    - 'GLAutoDrawable.setContext(GLContext newCtx, boolean destroyPrevCtx)', which calls
    - 'GLContext.setGLDrawable(GLDrawable readWrite, boolean setWriteOnly)'

  Exception: External context may be specialized.

  All drawable specific property handling shall be provided
  and implemented (if possible) via GLDrawable specializations.

- GLContext.isGLOrientationFlippedVertical() -> GLDrawable.isGLOriented()
  - PNGImage.createFromData() takes 'isGLOriented' to properly handle vertical flipping simply by line ordering
  - TextureIO's PNG writer passes TextureData's getMustFlipVertically() as isGLOriented to PNGImage.createFromData()
  - GLReadBufferUtil respects GLDrawable's isGLOriented() when creating TextureData instance.
  - Screenshot respects GLDrawable's isGLOriented()

- Screenshot is deprecated, use GLReadBufferUtil.

- Removed all PBuffer attributes, i.e. floatingPoint, RenderToTexture and RenderToTextureRectangle.
   - Allows removal of special pbuffer handling in GLContext* implementations.
   - Removed also from GLCapabilities*
   - Removed from deprecated GLPbuffer

  Impact:
    - Low, users who desire to render into a texture shall use our FBO GLOffscreenDrawable.
    - Only use case was the deprecated GLPbuffer
    - floating point framebuffer technology is still patented anyways :)

- Removed Java2DGLContext, which was only used for OSX's GLJPanel Java2D bridge,
  which is no more supported anyways.

From 0a7bf77b8c0765f8a53dc72a8edab8e0496938ff Mon Sep 17 00:00:00 2001
From: Sven Gothel <sgothel@jausoft.com>
Date: Wed, 8 May 2013 22:57:17 +0200
Subject: Refactor: TextureData's PixelAttributes/PixelBufferProvider ->
 GLPixelBuffer/.. and enhance usage; GLJPanel: Use GLPixelBuffer* API and
 SingleAWTGLPixelBufferProvider if possible.

Refactor: TextureData's PixelAttributes/PixelBufferProvider -> GLPixelBuffer/.. and enhance usage
  - GLPixelBuffer, GLPixelAttributes and GLPixelBufferProvider have potential for wider audience,
    hence extract them to package 'com.jogamp.opengl.util'.

  - Using GLPixelBuffer, shall attempt to use pack/unpack row-stride, i.e.
    GL2GL3.GL_PACK_ROW_LENGTH, or GL2GL3.GL_UNPACK_ROW_LENGTH.
    See GLReadBufferUtil and GLJPanel

  - AWTGLPixelBuffer*: Attribute 'row-stride' allows reusing a bigger buffer than requested.

GLJPanel: Use GLPixelBuffer* API and SingleAWTGLPixelBufferProvider if possible.
  - Use GLPixelBuffer API to remove redundancies

  - Attempts to use SingleAWTGLPixelBufferProvider to save JVM/CPU heap space
    for BuffereImage and IntBbuffer (readBack)

Added unit new test demonstrating multiple overlapping GLJPanels reusing (or not)
a singlton SingleAWTGLPixelBufferProvider.

Subject: GLJPanel: Add remark about FBO / GLSL texture-unit usage in API doc;
 Add API entry to set/get texture unit (default 0).

Allowing a user to set a specific texture-unit and to query the used texture-unit,
allows one to avoid a collision w/ own texture programming .. i.e. removes the burden to setup all params etc.

Subject: Remedy for Bug 782: Issue Debug.initSingleton() or Debug.debug(..)
 before calling 'PropertyAccess.isPropertyDefined(propName, default)' through
 Debug class.

Calling 'Debug.isPropertyDefined(propName, default)' may be 'optimized' to
'PropertyAccess.isPropertyDefined(propName, default)', which would skip the modules Debug's class initialization.

Iff that happens, an AccessControlException may happen, due to requesting an insecure property,
since modules own Debug class has not been added it's trusted prefixes from within it's init block yet.

This seems to be a bug of the JVM .. to me, however .. the above description is the only
able to explain the issue at hand.

+++

Fix calls Debug class own static methods, either Debug.initSingleton() or Debug.debug(),
before calling 'isPropertyDefined(propName, default)'.

+++

Also mark Debug class static methods final!

Subject: GLPixelBuffer*: Add componentCount==1 (ALPHA/RED), 'allowRowStride'
 utilization AWTGLPixelBuffer* -> GLPixelBuffer*

GLPixelBufferProvider:
  - Default*.getAttributes(): Add componentCount==1 (ALPHA/RED), validate values, throw exception if n/a or not supported
  - Add 'allowRowStride' (as for AWTGLPixelBufferProvider)
    - Add default for true and false

GLPixelBuffer:
  - Add 'allowRowStride' (as for AWTGLPixelBuffer)
  - Fix requiresNewBuffer(..):
    - aquire minByteSize if passed one is <= 0
    - validate minByteSize w/ currentByteSize according to allowRowStride.

AWTGLPixelBuffer: 'allowRowStride' impl. moved to GLPixelBuffer.

Subject: TileRenderer*: Enhance API Doc; Cleanup OO; Remove PMVMatrixCallback,
 use GLEventListener reshape(..) or manual reshape after beginTile(..) method.

GLEventListener reshape(..) method should be aware of TileRenderer usage
and get the missing tile position and image size from it (-> see Gears example).

TestRandomTiledRendering3GL2AWT demos AWT GLCanvas onscreen
being used for random tile rendering to produce a PNG file.

TestTiledRendering1GL2 is now GLAutoDrawable/GLEventListener agnostic,
hence demos plain GLDrawable tile rendering usage.

Subject: GLCanvas Printing WIP: Swap to offscreen at setupPrint(); Use
 TileRenderer @ print(..); Test: Add auto-print w/o UI 72dpi and 300dpi

NOTE: Tile raster is added at print plus lots of debug output - WIP!

- Swap to offscreen at setupPrint()
  - Swap GLEventListener (GLEL) and GLContext to fixed size offscreen GLAutoDrawable (GLAD)
  - Destroy onscreen drawable/context
  - Setup TileRenderer w/ offscreen GLAD
  - @ releasePrint() restore onscreen ..

  This shall ensure we don't hog the GPU resources when
  resizing the AWT component (upscaling).

- Use TileRenderer @ print(..)

  The clip-rect will be used as the TileRenderer's image-size
  and we perform a whole tile-rendering loop.

  This helps to limit resources, see above.

- Test: Add auto-print w/o UI 72dpi and 300dpi

From 76048cd784ea6df32f19e97bb228e4ead880ea07 Mon Sep 17 00:00:00 2001
From: Sven Gothel <sgothel@jausoft.com>

Subject: Test: Don't resize frame, tweek print-matrix; AWTPrintLifecycle: Add
 scale and convenient AWT container traversal context; GLCanvas/GLJPanel
 properly handle existing MSAA and req. AA;

- Test: Don't resize frame, tweek print-matrix
  - Use scaleComp72 to scale the frame to fit on page,
    i.e. global print matrix

  - Use scaleGLMatXY = 72.0 / glDPI
    to locally scale on the GL drawable as being passed to AWTPrintLifecycle.setup(..)

  - Hence frame stays untouched/stable, no need for 'offscreen' print test,
    which is removed.

- AWTPrintLifecycle: Add scale and convenient AWT container traversal context
  Use a simple decoration for all AWTPrintLifecycle impl. components within a container:

    final AWTPrintLifecycle.Context ctx = AWTPrintLifecycle.Context.setupPrint(frame, g2d, scaleGLMatXY, scaleGLMatXY);
    try {
    } finally {
       ctx.releasePrint();
    }

- GLCanvas/GLJPanel properly handle existing MSAA and req. AA;
  - GLCanvas: Workaround bug where onscreen MSAA cannot switch to offscreen FBO,
              i.e. stay 'onscreen'
  - GLJPanel: Use new offscreen FBO if MSAA is requested and not yet used.

- GLJPanel.Offscreen.postGL(): always swapBufer(), was missing for !GLSL swapping

Results GLCanvas / GLJPanel:
  - Good scaling
  - Stable behavior / visibility
  - High DPI mode works

Subject: Fix AWT printing issues w/ overlapping and/or non-opaque contents ;
 Change AWTPrintLifecycle's lifecycle

- AWTPrintLifecycle:
  - Should decorate:
       PrinterJob.print(..),
    instead of within Printable.print(..) { .. container.printAll(..); .. }

    This is due to AWT print implementation, i.e.
    AWT will issue Printable.print(..) multiple times for 'overlapping'
    or non-opaque elements!

  - Move from javax.media.opengl.awt -> com.jogamp.nativewindow.awt
  - Make _interface_ AWT agnostic, i.e. remove Graphics2D from 'setup(..)'
  - Add 'int numSamples' to 'setup(..)' to determine the number of samples

- AWTTilePrinter:
  - Use double precision when scaling image-size and clip-rect,
    then round them to integer values.
    Otherwise AWT will use the bounding box for the clipping-rectangular.

  - Clip negative portion of clip-rect,
    this removes redundant overpaints, as well as increasing the tile count
    due to the increased clipping-size.

  - Clip the image-size in the tile-renderer according to the clip-rect.

  - DEBUG_TILES: Dump tiles to file

  - Use sub-image of final BuffereImage instead
    of adding another clipping region. This might increase performance
    if no clip-rect has been set.

TODO:
  TestTiledPrintingGearsSwingAWT overlapping tests exposes
  a 'off by one' bug of the first layer's background!
  Note: The GL content seems to be correct though - maybe it's simply an AWT rounding error ..

Subject: AWTTilePainter.setupGraphics2DAndClipBounds(): Use 'Shape getClip()';
 Use double precicion clip bounds 'all the way'; Explicitly scale image and
 clip w/ current scaled transform.

- Use 'Shape getClip()'
  Don't assume Rectangle2D, but use Shape's getBounds2D()

- Use double precicion clip bounds 'all the way'
  Remove rounding error on clip bounds w/ start value, which was _not_ using doubles.

- Explicitly scale image and clip w/ current scaled transform.
  Instead of abusing Graphics2D's clip shape to scale image size and clip-area,
  explicitly use transform both bounding boxes into transformed space,
  scale space and transform out (inversion).
  A possible NoninvertibleTransformException will be thrown while Graphics2D has not been modified.

Subject: Fix Bug 826: GLJPanel: Fully restore TextureState and Viewport

In FBO mode save TextureState of current texture-unit,
as well as for the fbo texture-unit if the latter is a different.

In glslTextureRaster mode for verical flip (using FBO),
set the viewport to drawable size if before flipping and restore afterward - if equired.

TestGLJPanelTextureStateAWT fully tests use cases:
  - Keep texture bound w/ same or other texture-unit
  - Use 2 viewports within one drawable and keep it

From 4ef53cf2ae509a625795bfa3a8982ce75e24e83a Mon Sep 17 00:00:00 2001
From: Sven Gothel <sgothel@jausoft.com>
Date: Fri, 27 Sep 2013 07:13:24 +0200
Subject: TileRenderer*: TileRendererNotify -> TileRendererListener w/
 clarifying functionality (reshapeTile(..), ..); Only process GLEventListener
 impl. TileRendererListener; attachToAutoDrawable -> attachAutoDrawable, etc.

-TileRendererNotify -> TileRendererListener
  - Added methods:
    - void reshapeTile(TileRendererBase tr,int tileX, int tileY, int tileWidth, int tileHeight, int imageWidth, int imageHeight);
    - void startTileRendering(TileRendererBase tr);
    - void endTileRendering(TileRendererBase tr);

  allowing to clarify user code and API specification,
  i.e. TR only processes GLEventListener which impl. TileRendererListener.

  This also allows simplifying the API doc, while having a more descriptive
  reshape method focusing solely on tile rendering.

  Further more, the start/end TR methods allow certain GL related actions
  while the context is current before and after iterating through the tiles.
  This is even used for RandomTileRenderer (one tile only), to allow
  to reuse same TileRendererListener for diff TRs.

- Fix language, attach and detach usage was vice versa. We do attach an GLAutoDrawable to a TR
  - attachToAutoDrawable -> attachAutoDrawable
  - detachFromAutoDrawable -> detachAutoDrawable

- Adapted unit tests.

Subject: Fix AWT Printing: Use delegated GLDrawable's size for tile-size
 instead of AWT-GLAD's size, since the latter uses AWT's component size.

.. the AWT component size could have been modified after setupPrinting(..).

The AWT-GLAD getWidth() and getHeight() is implemented by AWT's component
and hence may not reflect the actual GLDrawable size while printing.

Subject: GLJPanel/AWTGLPixelBuffer: Reused BufferedImage didn't account for
 row-stride (regression of b33bdf41cf53f37203643a8551bf5d94b42a8fab)

SingleAWTGLPixelBufferProvider w/ allowing row-stride reuses the AWTGLPixelBuffer and it's BufferedImage
even w/ different width.

This leads to distortion if using the BufferedImage unhandled.

GLJPanel also set GL_PACK_ROW_LENGTH to pixelBuffer.width, which leads to an 'out-of-bounds'
exception if ReadPixels is used w/ panelwidth and panelHeight.

++

Introduce AWTGLPixelBuffer.getAlignedImage(width, height) which returns an aligned
BufferedImage while reusing the DataBuffer.

GLJPanel fetches a new alignedImage if required.

This allows a more efficient single buffer usage as intended, w/o the need of copying data.

Subject: AWTPrintLifecycle.setupPrint(..): Fix regression of commit
 a05b87a369441d9ef38f97929f866b3d4ced0e57: NULL printGLAD of GLCanvas and
 NewtCanvasAWT

We have to pre-init printGLAD w/ current GLAD (similiar w/ GLJPanel).

Also properly define reqNewGLAD:
   reqNewGLAD = !caps.getSampleBuffers() && ( reqNewGLADOnscrn || reqNewGLADSamples || reqNewGLADSize );

where '!caps.getSampleBuffers() && ( .. )' is due to Bug 830,
swapGLContextAndAllGLEventListener and onscreen MSAA w/ NV/GLX does not work.

From 7f7a23dd0ddf106e6f0c69fc2a05ff92ac56200e Mon Sep 17 00:00:00 2001
From: Sven Gothel <sgothel@jausoft.com>
Date: Sun, 27 Oct 2013 17:51:08 +0100
Subject: Bug 776 GLContext Sharing: Refine API for relaxed and lazy GLContext
 sharing ; Fix GLContext memory contract (volatile)

(Unit test remarks see below)

- Add shared GLContext queries
  - Refined GLContextShareSet:
    - Use IdentityHashMap since GLContext's can only be identical w/ same reference (footprint, performance)
    - Add API doc for clarification
    - Add methods:
       - ArrayList<GLContext> getCreatedShares(final GLContext context)
       - ArrayList<GLContext> getDestroyedShares(final GLContext context)
    - Use 'final' where possible

  - Add GLContext methods:
      - boolean isShared()
      - List<GLContext> getCreatedShares()
      - List<GLContext> getDestroyedShares()

- Add GLSharedContextSetter interface defining setting a shared GLContext
  directly (GLContext) or via a GLAutoDrawable:
  - setSharedContext(GLContext)
  - setSharedAutoDrawable(GLAutoDrawable)

  Both cause initialization/creation of GLAutoDrawable's drawable/context to be postponed,
  if the shared GLContext is not yet created natively or
  the shared GLAutoDrawable's GLContext does not yet exist.

  Most of impl. resides in GLDrawableHelper

  Implemented in:
    - GLAutoDrawableBase, GLOffscreenAutoDrawable
    - GLWindow
    - AWT GLCanvas

  TODO:
    - GLJPanel
    - SWT GLCanvas

- GLDrawableFactory:
   - Add 'GLOffscreenAutoDrawable createOffscreenAutoDrawable(..)' variant w/o passing the
     optional shared GLContext _and_ specifying lazy GLContext
     creation. This allows to benefit from GLSharedContextSetter contract.
     Lazy GLContext creation is performed at 2st display() call at the latest.

     All JOGL code and unit tests use this new method now.

  - Mark 'createOffscreenAutoDrawable(..)' w/ shared GLContext argument
    and immediate GLContext creation deprecated - shall be removed in 2.2.0

- Make reference to GLContext and it's native handle volatile
  Since we rely on the query 'GLContext.isCreated()' to properly allow GLAutoDrawable's to query whether
  a shared GLContext is natively created (already), the handle must be volatile
  since such query and the actual creation may operate on different threads.

+++++

- Add/Refine shared GLContext unit tests demonstrating diff. sharing methods.

  All variants of using shared GLContext:
      com.jogamp.opengl.test.junit.jogl.acore.TestSharedContextVBO*

  Most convenient way to share via setSharedAutoDrawable(GLAutoDrawable):
      com.jogamp.opengl.test.junit.jogl.acore.TestSharedContextVBOES2[NEWT|AWT]3

  AWT use w/ JTabbedPane using setSharedAutoDrawable(GLAutoDrawable):
      com.jogamp.opengl.test.junit.jogl.acore.TestSharedContextWithJTabbedPaneAWT

Subject: Bug 776 GLContext Sharing: Add note about driver stability
 (destruction order) ; Fix unit tests (Shared Gears, wait for created context
 and destruction order)

- Add note about driver stability (destruction order)
  - See GLSharedContextSetter: Don't destroy master context before slaves!

- Fix spec-overview.html#SHARED links, add link to GLSharedContextSetter in SHARED subsection.

- Fix unit tests (Shared Gears, wait for created context and destruction order)
  - The GearsObject sharing was completly bogus!
    It simply used the _same_ GLArrayDataServer instance for sharing,
    but it should use a _copy_ of the shared GLArrayDataServer while
    only preserving the VBO object!
    Fixed, while adding required methods to GLArrayDataServer.

  - Waiting for the created GLContext of a GLAutoDrawable required us
    to pass the latter _and_ check whether it's GLContext exists and is natively created.

  - Accomodated the destruction order - see above!

Subject: Bug 888 / Bug 891- Enhance GLCapabilities-Query: Add perf. test case

Even though the test case itself cannot show the proper initialization time,
it can be used w/ an attached profiler i.e.

    Test w/ 50 X11GLXGraphicsConfigurationFactory.chooseGraphicsConfigurationFBConfig() invocations:
      - pre change:  1.708 ms
      - post change:   650 ms  (613e33ee8ffc1f2b9c5db1e1b5bb5253a159ed6d)

Subject: Bug 904 - GLJPanel: Add property to skip isGLOriented() based
 vertical flip by default (2/2)

Property 'jogl.gljpanel.noverticalflip' will set the skipGLOrientationVerticalFlip default to true - intended for perf. testing of existing applications

Subject: Bug 906 - JAWTWindow Component- and HierarchyListener must be
 detached at JAWTWindow.destroy() - GLCanvas Recreation Case

In case a JAWTWindow owner recreates itself, destroying JAWTWindow must detach the
Component- and HierarchyListener from the AWT component!

Test TestBug816GLCanvasFrameHoppingB849B889AWT
shows properly detaching listener at jawtWindow destruction.

Subject: Bug 909 - Reccreate GLJPanel's BufferedImage is no more sourced by
 singleton AWTGLPixelBuffer

GLJPanel must validate whether it's local BufferedImage's DataBuffer is sourced
by the current singleton AWTGLPixelBuffer.

Case:
GLJPanel-B has created a new singleton AWTGLPixelBuffer w/ increased size.
Previous created GLJPanel-A's local BufferedImage's DataBuffer is no more sourced
by the singleton AWTGLPixelBuffer and hence must be re-created.

Subject: GLJPanel.initializeBackend(offthread=true): Enable on Windows, thanks
 to Bug 907 impl. DummyDispatchThread (DDT)

Bug 907 implemented DDT used to create and destroy offscreen surface's dummy drawable on Windows.
This enables offscreen initialization on Windows running from a short lived arbitrary thread.

Subject: Bug 937 - JAWTWindow: Unsatisfying Visibility Computation

Simplify JAWTComponentListener's HierarchyListener:
  - Don't interfere w/ Component's visibility anymore!
    This shall reduce sideeffects.
    Utilize 'isShowing' in each Component specialization, i.e. GLCanvas.

  - On SHOWING_CHANGED if a parent caused a change
    of the tracked components showing state,
    propagate it to the offscreen-layer!

  - Remove all other complicated states!

GLCanvas, GLJPanel:
  - Instead of 'isVisible()' use 'showing state',
    since only the 'showing state' reflects 'true' visibility
    throughout the hierarchy.

  - Add HierarchyListener and track volatile showing state
    to be used instead of 'isVisible'.
    Using a cached showing state is more efficient
    than quering 'isShowing()' all the time!

NewtCanvasAWT:
  - Use 'isShowing()' instead of 'isVisible(), see above

Subject: Better shared GLAutoDrawable synchronization: Block slave instances
 to also block until all master's GLEventListener.init(..) methods have been
 called

Better shared GLAutoDrawable synchronization.
Block slave instances to also block until all master's GLEventListener.init(..) methods have been called

- GLSharedContextSetter: Add areAllGLEventListenerInitialized()
  - GLCanvas (SWT, AWT)
  - GLJPanel
  - GLAutoDrawableBase (GLWindow, ..)

- GLDrawableHelper's isSharedGLContextPending(..)
  takes 'areAllGLEventListenerInitialized()' into consideration
  allowing to block the slave creation until master is completed.

This solves teh use case, where the master creates resources in it's
GLEventListener initialization (buffers), which are shared with
it's slaves.

Subject: Bug 975 - GLJPanel's OffscreenDrawable shall not double swap (custom
 swap by GLEventListener using [AWT]GLReadBufferUtil)

When utilizing [AWT]GLReadBufferUtil it is usually desired to read from the front-buffer
instead the back-buffer. The latter may not be defined, e.g. when using MSAA.

A GLEventListener utilizing [AWT]GLReadBufferUtil,
must perform the drawable.swapBuffers() to be able to read from the front-buffer.

Usually GLAutoDrawable.setAutoSwapBuffer(false) should be called here,
to avoid a double swap - however GLJPanel does not support toggling auto-swap
since it requires to control swap for it's own read-pixels.

Remedy for GLJPanel:
  - GLJPanel issues helper.setAutoSwapBufferMode(false) - immutable

  - Enable GLJPanel.swapBuffer() if initializes
    This was previously disabled.

  - GLJPanel's OffscreenBackend listens to  surfaceUpdated,
    to be notified whether postGL needs to swap buffer
    or the drawable.swapBuffer() was already called between preGL and postGL.

See unit tests adding/removing a snapshot GLEventListener
performing swapBuffers() and setting auto-swap accordingly.

Subject: Bug 975 - GLJPanel's OffscreenDrawable shall not double swap - Use
 default auto-swap mechanims

Refines commit 908ebd99d1eb57ce773a1fdd67c76886da86b9e6

Note that the test case decide whether to auto-swap (after read-pixels)
or not auto-swap (manual swap before read-pixels).

See UITestCase.swapBuffersBeforeRead(GLCapabilitiesImmutable chosenCaps):
   Determines whether the chosen GLCapabilitiesImmutable requires a swap-buffers before reading pixels.

   Usually one uses the default-read-buffer, i.e. GL.GL_FRONT for single-buffer
   and GL.GL_BACK for double-buffer GLDrawables
   and GL.GL_COLOR_ATTACHMENT0 for offscreen framebuffer objects.
   Here swap-buffers shall happen after calling reading pixels, the default.

   However, multisampling offscreen GLFBODrawables utilize swap-buffers to downsample
   the multisamples into the readable sampling sink.
   In this case, we require a swap-buffers before reading pixels.

   Returns:  chosenCaps.isFBO() && chosenCaps.getSampleBuffers()

+++

- GLJPanel:
  - Remove SurfaceUpdatedListener mechanism in favor of
    default auto-swap-buffer via GLDrawableHelper.
    This removes complexity.

  - postGL does not need to perform explicit swapBuffer operation,
    but rely on GLDrawableHelper and the default mechanism.
    This is also compatible w/ J2D backend.

  - Use GLDrawableHelper for setAutoSwapBufferMode(..) and getAutoSwapBufferMode()

+++

UnitTests:

- UITestCase:
  - Add 'boolean swapBuffersBeforeRead(GLCapabilitiesImmutable chosenCaps)'
    to determine whether swapBuffers() must occure before read-pixels. See above.

- GLReadBuffer00Base*
  - remove explicit addSnapshotGLEL/removeSnapshotGLEL

  - add TextRendererGLEL, to display frame-count and -dimension

  - SnapshotGLEL*
    - simply toggle auto-swap in their init(..) and dispose(..) method!

    - clear back-buffer if 'swapBuffersBeforeRead'
      to test whether the right buffer is being used for read-pixels.

Subject: Bug 975 - GLJPanel's OffscreenDrawable shall not double swap - Fix
 auto-swap mechanism ; Refined API doc getDefaultReadBuffer() ; Add
 GLDrawableUtil.swapBuffersBeforeRead(..)

Commit 82f679b064784213591b460fc5eaa1f5f196fbd1 which introduces the default swap-buffers
mechanism is erroneous:

The OffscreenBack backend requires the following operation order:

Order-1:
  [1] - GL display
  [2] - GL swapBuffers (always due to single-buffer non-MSAA or MSAA offscreen drawable)
  [3] - readPixels

+++

Commit 82f679b064784213591b460fc5eaa1f5f196fbd1 however introduced:

Order-2:
  [a] - GL display
  [b] - readPixels
  [c] - GL swapBuffers (always due to single-buffer non-MSAA or MSAA offscreen drawable)

since [a] and [b] happened in Updater's display method, and [c] followed the same
triggered by GLAutoDrawableHelper.

+++

The proof, commit d46d9ad8f998a7128d9f023294d5f489673d6d8a, is faulty,
since it always included the 'snapshot' GL event listener
which turned-off auto-swap and swapped before read-pixels.
TL;DR it enforced proper Order-1.

+++

This fix allows the Backend to intercept disable GLDrawableHelper's setAutoSwapBufferMode(..)
and perform the auto-swap mode itself in the proper Order-1.

The unit test has been refined to optionally disable the snapshot
to validate auto-swap mode.

+++

Refined GLBase and GLContext's API doc for 'getDefaultReadBuffer()'

+++

Add GLDrawableUtil.swapBuffersBeforeRead(..)
and reuse it for TileRendererBase (original impl.).
